Frequency doubling in the Cerenkov regime utilising an abnormal reflecting mirror structure

摘要

Abnormal reflecting mirror (ARM) structures, consisting of a corrugated optical waveguiding structure, can serve as a narrow band reflection filter in which strong field enhancement may occur by excitation of the guided mode. The latter is quite interest for SHG. We report experimental results of a first prototype, which exhibits CSHG in the ARM structure.
