We present a silicon photonic beam steering device based upon an 8 x 8 grating coupler focal plane array fed by a MZI switching tree. Transmission of the light from the grating couplers is made through the back side of the chip using topside mirrors.

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.

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.

The spectral dependence of the linewidth enhancement factor of silicon based InAs/GaAs quantum dot lasers is investigated above the threshold by using a phase modulation method. Low values of linewidth enhancement factor measured at twice the threshold are reported. Such results confirm the high quality of the quantum dot material.

Reservoir computing (RC) replaces the backbone of deep neural networks with the dynamics of a complex physical system in which only the output synapses are trained. Optical phenomena form a natural substrate for these architectures, while integrated optics can be used to enhance the nonlinear effects. Here, we propose and experimentally validate an all optical RC scheme based on a silicon on insulator microresonator (MR) and time multiplexing. We give proof of concept demonstrations of RC by solving two nontrivial tasks: the delayed XOR and the classification of the Iris flowers dataset. The approach could be scaled up to realize large hybrid spatio-temporal reservoirs of increased computational speed and complexity.

We review membrane InP-based modulators and a laser, which are fabricated by combining wafer bonding and epitaxial regrowth of materials with different bandgaps on Si. We demonstrate a high-efficiency Mach-Zehnder modulator integrated with a distributed feedback laser and high-speed electro-absorption modulator on Si-waveguide circuits.
