Integrated Optical Gas Sensors on Silicon-on-Insulator Platform

We demonstrate highly sensitive micro-optical hydrogen and ethanol sensors on SOI microring resonators (MRR) using chemical coatings sensitive to the corresponding gases. Hydrogen concentrations below the lower explosion limit and ethanol vapor concentration below 100ppm are detected. ©2010 Optical Society of America OCIS codes: (000.0000) General; (000.0000)

A compact and low loss 90° optical hybrid on a silicon-on-insulator platform

We present a compact and low loss 90° optical hybrid on a silicon-on-insulator (SOI) platform for coherent receiving systems. Our 90° optical hybrid uses a novel topology, comprising one Y-junction and three 2x2 multimode interference (MMI) couplers. The geometry of the 90° optical hybrid is fully optimized using particle swarm optimization (PSO). The fabricated 90° optical hybrid has a compact...

Monolithic optical link in silicon-on-insulator CMOS technology.

This work presents a monolithic laterally-coupled wide-spectrum (350 nm < λ < 1270 nm) optical link in a silicon-on-insulator CMOS technology. The link consists of a silicon (Si) light-emitting diode (LED) as the optical source and a Si photodiode (PD) as the detector; both realized by vertical abrupt n+p junctions, separated by a shallow trench isolation composed of silicon dioxide....

Pd-based integrated optical hydrogen sensor on a silicon-on-insulator platform.

We have experimentally demonstrated a compact, integrated optical hydrogen sensor on a silicon-on-insulator platform. The sensor consists of silicon waveguide coated with a thin palladium film. The sensitivity and response time of the sensor was tested for volumetric hydrogen concentrations ranging from 0% to 4%. The proposed hydrogen sensor shows great potential as a building block for an opti...
