Mechanical stabilisation and tuning method for photon crystal filter used in optical fibre communications
摘要
The method involves filling the hollow spaces in the filter, e.g. which is structured as a photon crystal, with optically transparent material of adjustable refractive index. The filled filter is subjected to an electrical field of variable field strength. The optical characteristics, e.g. the refractive index for transmitted and reflected light in the crystal's hollow chamber, fine tuning of the transmitter amplitude and fine tuning of the light phase shift are adjusted by varying the field strength of the electric field.
