Abstract

The sensitivity of current gravitational wave detectors is limited by a variety of noise sources. Further improvements require significant modifications in the interferometer structure and operation. Operating at cryogenic temperatures, increasing laser power, and changing the optics materials are some of the proposed modifications for future gravitational wave detectors. The excellent properties of silicon at cryogenic temperatures make it one of the most interesting materials for future test masses. However, using Si test masses has some challenges, such as birefringence. In this thesis, some of the main silicon properties for use in future gravitational wave detectors were discussed.
