7 March 2014 Optomechanical cantilever device for displacement sensing and variable attenuator
Author Affiliations +
An optomechanical dual cantilever device has been fabricated with applications as a displacement sensor and variable attenuator. A novel fabrication approach using a precision dicing saw has benefits for fabrication time, cost and energy consumption. The displacement sensor sensitivity is 0.8 dB/micron and a suppression ratio of 25 dB is obtained when the device is used as an attenuator.
