A 10 Gb/s transmitter composed of a sampled-grating DBR (SGDBR) laser and Mach-Zehnder modulator was fabricated on a dual-quantum-well integration platform. The device exhibited error free operation and negative chirp
The paper discusses on devices commonly used for optical information systems - computation or communication based. The list includes: semiconductor lasers and laser arrays; passive optical elements such as lenses, prisms, gratings and resonators; SLMs, optical interconnection elements, optical memory; spectral and polarization filters; wavelength multiplexers and demultiplexers; optical waveguides;...
A very shallow multilayer etched-grating is proposed as a wavelength demultiplexer. Two different configurations are compared for diffraction efficiency and resolution. Single-step-etch fabrication designs are presented and modeled for their grating efficiency and overall performance
We demonstrate our low-cost, silicon-based PLC platform for FTTH applications, which includes a novel reflective grating technology with extremely wide free-spectral range, and passive hybridization technique for on-chip lasers and photodetectors
The rejection level is improved from 17 to 45 dB and the back reflection suppressed from mu1 to mu13 dB in a PLC-type slanted-grating simply by increasing the waveguide width from 8 to 28 mum
