Hybrid silicon evanescent approach to optical interconnects
We discuss the recently developed hybrid silicon evanescent platform (HSEP), and its application as a promising candidate for optical interconnects in silicon. A number of key discrete components and a wafer-scale integration process are reviewed. The motivation behind this work is to realize silicon-based photonic integrated circuits possessing unique advantages of III–V materials and silicon-...
متن کاملHybrid silicon evanescent devices
The indirect bandgap of Si has been a key hurdle in the achievement of optical gain elements. Raman lasers and amplifiers1-3 have been demonstrated, and optical gain in nanopatterned Si4 has also been observed, but an electrically pumped all-Si gain element has yet to be realized. An alternative to creating an electrically pumped all-Si gain mechanism is to take prefabricated lasers and couple ...

The structure and design of a hybrid silicon evanescent amplifier, incorporating III-V offset quantum wells bonded on a silicon waveguide, is proposed and discussed.
متن کاملElectrically pumped hybrid AlGaInAs-silicon evanescent laser.
An electrically pumped light source on silicon is a key element needed for photonic integrated circuits on silicon. Here we report 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. This laser runs continuous-wave...
متن کاملA hybrid AlGaInAs-silicon evanescent waveguide photodetector.
We report a waveguide photodetector utilizing a hybrid waveguide structure consisting of AlGaInAs quantum wells bonded to a silicon waveguide. The light in the hybrid waveguide is absorbed by the AlGaInAs quantum wells under reverse bias. The photodetector has a fiber coupled responsivity of 0.31 A/W with an internal quantum efficiency of 90 % over the 1.5 mum wavelength range. This photodetect...
