Silicon Based Ir Filters, Prakash Mokashi

Theses

The design and fabrication of silicon based IR (Infrared) filters for high-speed optical communication systems are the topic of this thesis. Its novelty is in two aspects: 1) Use of silicon wafers as an optical guiding medium; 2) Use of wafer bonding technique to attach two optical elements together.

The structure consists of two optical waveguides, the bus waveguide and the drop channel waveguide. A ring on top of these waveguides couples them in such a way that only one narrow spectral line is removed from the bus waveguides which propagates in the dropchannel waveguide. The assembly is fabricated using …
