OPTICAL FUNCTION DEVICE WITH PHOTONIC BAND GAP AND/OR FILTERING CHARACTERISTICS

摘要

A stacked material free from a degraded quality of crystal, formed with a precise periodicity, and fabricated without relying on the vapor phase growth method is provided. An optical function device using the stacked material is also provided. A starting stacked material composed of two alternate layers (A), (B) having different refractive indexes is stacked over two periods or more by a substrate bonding method to provide a multi-periodic stacked structure.
