DISORDER-BASED MULTI-CHANNEL INDEPENDENTLY-ADJUSTABLE LOCAL OPTICAL FILTER AND DESIGN METHOD THEREFOR

摘要

A disorder-based multi-channel independently-adjustable local optical filter and a design method therefor. In the design of the local optical filter, the disorder of a reflector-cavity structure is regulated, and an intensity separation degree serves as a criterion for a disorder adjustment effect. By means of multiple optimization processes on the disorder of the reflector-cavity structure, all channel wavelengths and channel outer wavelengths finally reach a pre-set intensity separation degree, which is reflected as the transmittance, approximate to one, at the channel wavelength and the transmittance, approximate to zero, at the channel outer wavelength in the aspect of transmission performance.
