PROJECT UNDERTAKEN

Integrated Long period waveguide as tunable filter (Fabrication &Designing)”under the Guidance of DR. Suchandan Pal, Scientist in CEERI, Pilani in Opto-Electronics Devices Group.

 The aim of the project was to Design & fabricate a Long Period integrated waveguide to work as a filter for the wavelength of 1.55µm using the Silicon on Sapphire technology. The Designing of the waveguide was done using Professional Software Opti-Grating. After Designing, all the IC Fabrication steps like lithography, Oxidation, Metallization etc; were used for the fabrication. 

 Purpose of Project:

The project was sponsored by Department of Science & Technology, Govt. of India, for the application in Communication System so that only single Wavelength could reach the desired destination.
