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.

We report on an epitaxial Ge-on-Si dual-band photodetector grown on a Si p-n junction, to form two photodiodes connected in a back-to-back configuration. The device responsivity can be tuned, with an external bias, to cover wavelengths within the visible and near-infrared spectral regions.

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.
