PHOTONIC CRYSTAL INTERFEROMETER

摘要

A sensor apparatus comprising a photonic crystal structure optically coupled to a laser, the photonic crystal structure comprising a beam splitter, an interferometer (804) having a reference arm (808) and a sensor arm (806), a first output (832) configured to be optically coupled to a bright port photodetector, and a second output (834) configured to be optically coupled to a dark port photodetector.
