Title: Probing the inner workings of quantum photonic devices

Abstract: Scanning probe microscopy, including scanning spreading resistance microscopy, scanning capacitance microscopy and scanning voltage microscopy (SVM), is a novel and enabling tool to quantitatively probe internal dopant profile, voltage distribution and carrier distribution at nanometer scales. Scanning probe microscopy has been applied to a few representative photonic devices – buried heterostructure (BH) lasers, ridge waveguide lasers, terahertz (THz) quantum cascade lasers (QCL) and interband cascade lasers (ICL). The experimental results demonstrate that the unique SPM technique can reveal the inner workings, thus connect internal mechanism with external measures. The demonstration of resolving dynamic charge carrier density distribution and electric potential profile in an operating optoelectronic laser device is unprecedented and could open the door to many future applications in probing the underlying mechanisms for many puzzling issues such as sub-par performance and degradation in nanoelectronic devices, quantum devices and optoelectronic devices.

Title: High-performance hybrid silicon and lithium niobate optical modulators

Abstract: Optical modulators are at the heart of optical communication links. Ideally, they should feature low loss, low drive voltage, large bandwidth, high linearity, compact footprint and low manufacturing cost. Unfortunately, these criteria have been achieved only on separate occasions. Based on a silicon and lithium niobate hybrid integration platform, we demonstrate Mach–Zehnder modulators that simultaneously fulfil these criteria. The high-performance modulator is realized by seamless integration of a high-contrast waveguide based on lithium niobate—a popular modulator material—with compact, low-loss silicon circuitry. The hybrid platform demonstrated here allows for the combination of ‘best-in-breed’ active and passive components, opening up new avenues for future high-speed, energy-efficient and cost-effective optical communication networks.

Title: Tunable optoelectronic oscillator based on silicon micro-ring resonator

Abstract: A new silicon optoelectronic oscillator (OEO) system is proposed and experimentally demonstrated. The proposed OEO, generates the microwave signal by beating the un-modulated and amplitude-modulated versions of the same laser source. The drop port of a silicon micro-resonator is used to select one of the side band lobes generated by the amplitude modulation, thus serving as frequency selective element in the OEO. In this scheme, the microwave frequency generated is determined by the wavelength separation between the laser and the ring resonance. Thus, seamless microwave frequency tuning can be achieved just by sweeping the wavelength of the laser source. A proof-of-concept demonstration is implemented, experimentally showing microwave frequency generation in the range from 5.9 GHz to 18.2 GHz.

Title: Realizing Lorentzian, Fano and EIT resonance lineshapes in a microring resonator

Abstract: Microring resonators, as a fundamental building block of photonic integrated circuits, have been well developed into numerous functional devices, whose performances are strongly determined by microring's resonance lineshapes. In this talk, we propose two compact structures to reliably realize Lorentzian, Fano, and electromagnetically induced transparency (EIT) resonance lineshapes in a microring resonator. In the first structure, by simply inserting two air-holes in the side-coupled waveguide of a microring, a Fabry-Perot (FP) resonance is involved to couple with microring's resonant modes, showing Lorentzian, Fano, and EIT lineshapes over one free spectral range of the FP resonance. The quality factors, extinction ratios, and slope rates in different lineshapes are discussed. At microring's specific resonant wavelength, the lineshape could be tuned among these three types by controlling the FP cavity's length. Experiment results verify the theoretical analysis well and represent Fano lineshapes with extinction ratios of about 20 dB and slope rates over 280 dB/nm. In the second structure, a single air-hole is inserted into the bus-waveguide coupled with a microring, which functions as a phase shifter. Fano resonance lineshapes are obtained at each resonant wavelengths. The obtained slope rate and extinction ratio of the Fano resonant lineshapes are 22.2 dB and 557.33 dB/nm, respectively. The reliably and flexibly tunable lineshapes in the compact structure have potentials to improve microring-based devices and expand their application scopes.

Title: Infrared hyperbolic metasurface based on nanostructured van der Waals materials

Abstract: Hyperbolic metasurfaces with strongly anisotropic optical properties supports deep subwavelength-scale confined surface polaritons, which present a hyperbolic dispersion. They could extremely enhance light-matter interaction at mid-infrared and terahertz frequencies (corresponding to energies of molecular vibrations, and thermal emission and absorption) for photonic and thermal applications, such as heat management, chemical sensing and deep subwavelength imaging. However, hyperbolic metasurfaces working at these frequencies have not been developed yet due to the required challenging fabrication. In this work, we realize the first mid-infrared hyperbolic metasurface by nanostructuring a thin layer of hexagonal boron nitride —a prototypical van der Waals (vdW) polar material, which supports mid-infrared phonon polaritons with strong electromagnetic field confinement, ultraslow group velocities and long lifetimes. We used scattering-type scanning near-field optical microscopy to directly observe phonon polaritons emerging from the hot spot at the extremity of an infrared antenna and propagating through the metasurface with in-plane hyperbolic dispersion, which assembles the concave (anomalous) wavefronts of a diverging polariton beam. These results show that near-field microscopy can be applied to reveal the exotic wavefronts of polaritons in anisotropic materials, and demonstrate that nanostructured vdW materials can form a highly variable and compact platform for hyperbolic infrared metasurface devices and circuits.

Title: Design and fabrication of lateral metastructures for VCSELs

Abstract: Vertical-cavity surface-emitting lasers (VCSELs) have wide applications in data communication, sensing, and consumer electronics, because they have many advantages, such as circular beam, low power consumption, high modulation speed, low cost, high reliability, and 2D array configuration. In this talk, we will present two types of subwavelength gratings with a broadband high reflectivity for VCSELs. These subwavelength gratings are fabricated on GaAs/Ga0.51In0.49P layers with selective etching process and GaAs/Al0.9Ga0.1As layers with wet oxidation process. The measured reflectivity spectra are consistent well with the calculated result. These subwavelength gratings can serve as reflectors for VCSELs and tunable VCSELs.

Title: Multi-mechanism synergistic photodetectors based on low-dimensional materials

Abstract: Broadening the spectral range of photodetectors is an essential topic in photonics. Traditional photodetectors have been widely used, however, the realization of ultrabroad spectrum photodetectors remains a challenge. Here, a photodetector constructed by a hybrid quasi-freestanding structure of  ferroelectrics  with low-dimensional (LD) semiconductors is presented. The  LD materials with ultra thin structure brings a great benefit of heat dissipation for the thermal infrared detector. By coupling the mechanisms of pyroelectrics, photoconductor and phototransistor effect, an ultrabroad spectrum response ranging from ultraviolet to long-wavelength infrared  is achieved. This approach constitutes a reliable route towards realizing high-performance photodetectors with a remarkable ultrabroad spectrum response, high responsivity, low power consumption, and room-temperature operation.

Title: Spatiotemporal manipulation of optical fields with metasurfaces

Abstract: In this talk, I will explain how optical metasurfaces, planar arrays of subwavelength electromagnetic structures that collectively mimic the functionality of much thicker conventional optical elements, can be employed for shaping light in both spatial and temporal domains. I will first show that by patterning loss-less dielectric materials through a high-aspect-ratio nano-patterning Damascene process, high-performance transmission-type metasurfaces can be realized at visible and ultraviolet (UV) frequencies, which include TiO2-based devices operating in the visible and performing spin-controlled Airy beam generation, and HfO2-based devices operating at UV frequencies, including within the deep-UV range, and performing representative wavefront shaping functions such as lensing, beam bending, and hologram projection. Then, I will show that metasurfaces can be also leveraged to modulate the temporal profile of a near-infrared femtosecond pulse and achieve finely tailored pulse shaping operations such as splitting, compression, chirping, and higher-order distortion.
