Non-Orthogonal Modes in Passive Photonic Crystals

摘要

There has been significant interest in the non-orthogonal modes in resonator systems in the context of the excess noisefactor in laser cavities. Conventional non-orthogonal modes are created by the gain of the laser cavity during a round tripsince gain makes the propagation of light non-unitary. Here, we theoretically demonstrate that these non-orthogonalmodes can also be generated in passive photonic crystal systems. We further show that it can have a broader implicationin optical resonator systems. In particular, we probe the characteristics of non-orthogonal modes in a resonator system bylooking at the transport properties.
