We propose and investigate two-dimensional spatial coherent matched detection using high-speed photodiode array. Without optical spatial filtering/splitting, all mode-division multiplexed (MDM) channels are coherently demultiplexed and detected, ideally yielding 3-dB optical loss for any MDM signals.

We review our work on GaN high-speed LEDs. By optimizing MQWs structure in our device, record-high data rates (5.5 Gbit/sec) over POF among all visible LEDs can be achieved. Besides, a high-lumens, high-CRI (95), and high-speed white-light LED has been demonstrated for indoor VLC.

III-V semiconductor heterostructures grown on GaSb and InAs substrates are widely used to produce high performance optoelectronic devices operating in the technologically important mid-infrared spectral range. However, these substrates are expensive, only available in small sizes and have low thermal conductivity. Integration of III-Vs onto silicon substrates offers the opportunity to overcome these shortcomings and opens the possibility of new applications in lab-on-chip MIR photonic integrated circuits. However, the unusual III-V/Si interface and large lattice mismatch presents challenges to epitaxial growth. Here, we report on novel techniques employed to grow high quality Sb-based optoelectronic devices on silicon using molecular beam epitaxy.

We investigate how the lattice geometry affects the collective modes supported by nanoplasmonic arrays. Experimental measurements show that arrays with different geometries have different dispersions which are also dependent on the polarization. We further study the possibility of observing topologically nontrivial phenomenon in plasmonic system.

We report the first foundry-fabricated photonic integrated circuit (PIC) optical phase lock loop (OPLL) tuneable active optical filter for optical frequency comb line selection and amplification. The PIC containing DBR lasers and photodiodes is integrated with low frequency electronics to create an OPLL, which functions as a highly selective optical filter with sub-GHz bandwidth and 50dB out-of-band suppression. The OPLL output is a single tone coherent with the comb line, whose optical power is 6dB higher than the selected input line, and whose frequency can be offset from the input line by an agile and precisely defined frequency.

Topographically anisotropic photonics is used to demonstrate polarization-selective microring resonators and beam taps. Both fabricated devices exhibit strong polarization-selectivity. The beam tap is shown to be broadband, as it retains this selectivity over a bandwidth of over 80 nm.

The Raman effect causes higher-order solitons to break apart, leading to inter-symbol interference, even in the ideal case without propagation losses. The power threshold of this effect is 10 dBm for a two-eigenvalue QPSK system.

Electro-optically switchable photonic components based on zenithal bistable liquid-crystal gratings are designed and theoretically investigated. By properly selecting the material and geometrical parameters, we demonstrate that such gratings can operate as switchable beam splitters, beam steerers, quarter-wave plates, and narrowband guided-mode resonant filters. The switching dynamics of the proposed components are also investigated by employing a tensorial formulation for the liquid-crystal orientation problem, which is coupled with the lightwave propagation studies in a multiphysics environment based on the finite-element method.
