A novel, low-drive-voltage, and compact modulator using serially-coupled ring resonators in a Mach-Zehnder interferometer (MZI) linearly reduces the modulator’s energy consumption as the number of rings in the chain increases. Such an MZI with three serially-coupled rings is invested for typical silicon photonics platforms.

We propose a broadband and compact polarization splitter-rotator based on subwavelength-grating-slot-assisted adiabatic coupler for the silicon-on-insulator platform. Simulated crosstalk below -18.6 dB and insertion loss below 0.49 dB over a 100 nm bandwidth is achieved with a sub-100-µm device length.

A laser sintering fabrication process to deposit 3 µm thick GeSn films on silicon substrates has been demonstrated. A 2% tin was incorporated in germanium to increase p-type mobility. High hole mobility of 166.2 cm2/v.s was achieved for laser-sintered polycrystalline GeSn films.

We propose an approach to actively mitigate spectral distortions induced by nonlinear phenomena in microring resonator silicon photonic filters. The benefit of this scheme has been evaluated through transmission assessments, performed for 200 Gbit/s DP 16-QAM signals, up to 20 dBm.

Optical photodetectors are at the forefront of integrated photonics research as fundamental building blocks for optoelectronic systems and communication links. However, chip-integrated photodetectors with improved performances constitute on-going challenges for such applications. We present recent progress in high-speed silicon-germanium photodetectors fabricated on silicon-foundry-compatible platforms.

The Crosstalk Elimination via Perturbative Reshaping (CEPR) design method is introduced to ensure low modal crosstalk in adiabatic devices. It is applied to design a 2x2 coupler that experimentally achieves 50±1% split ratio and <0.1 dB loss over a 100 nm span in the O-band.

We modelled thermal effects in InP-on-Si nanocavity lasers with various pumping strategies. The highest temperature under uniform pumping increases linearly with diameter while it shows a maximum under Gaussian distributed pumping. Transient results show both pulse width and period play important role in thermal effects.

We present an integrated electro-optical modulator based on a Schottky diode embedded in a graded-index SiGe waveguide, operating in a wide mid-IR range from 6.4 to 10.7 µm wavelength. A 1.3 dB absorption variation is reported, which is already compatible with onchip synchronous detection experiments.
