Abstract
In this paper, MEMs solution of the biosensor based on optical feedback interferometry is presented. Optical feedback occurs when part of the emitted laser light is coupled back into the laser cavity. The light interacts with the original laser light producing an interference signal which is detected using a photodetector placed on the opposite side of the laser cavity
