High speed quantum-well lasers and carrier transport effects
Carrier transport can significantly affect the high-speed properties of quantum-well lasers. The authors have developed a model and derived analytical expressions for the modulation response,
All-optical label swapping networks and technologies
All-optical label swapping is a promising approach to ultra-high packet-rate routing and forwarding directly in the optical layer. In this paper, we review results of the DARPA Next Generation

Monolithic germanium/silicon avalanche photodiodes with 340 GHz gain-bandwidth product
Significant progress has been made recently in demonstrating that silicon photonics is a promising technology for low-cost optical detectors, modulators and light sources1,2,3,4,5,6,7,8,9,10,11,12.
Electrically pumped hybrid AlGaInAs-silicon evanescent laser.
An electrically pumped AlGaInAs-silicon evanescent laser architecture where the laser cavity is defined solely by the silicon waveguide and needs no critical alignment to the III-V active material during fabrication via wafer bonding is reported.
Ultrawide-band long-wavelength p-i-n photodetectors
We compare different designs for very high-speed (millimeter-wave) long-wavelength photodetectors, different materials for such detectors, and different ways of characterizing the speed of these
Recent progress in lasers on silicon

Novel concept for ultracompact polarization splitter-rotator based on silicon nanowires.
A novel concept for an ultracompact polarization splitter-rotator is proposed by utilizing a structure combining an adiabatic taper and an asymmetrical directional coupler, which is compatible with the standard fabrication for the regular photonic integrated circuits based on SOI nanowires.

This work addresses narrow-linewidth tunable lasers as one of key components of low phase noise photonic microwave signal generators and shows the possibility of achieving sub-kHz linewidths by utilizing on-chip high-Q ring resonators.
Ultra-low-loss high-aspect-ratio Si3N4 waveguides.
An approach to make ultra-low-loss waveguides using stable and reproducible stoichiometric Si3N4 deposited with low-pressure chemical vapor deposition is characterized, projecting that 0.1 dB/m total propagation loss is achievable at a 7 mm bend radius with this approach.
