A M Zheng, J S Seeley, R Hunneman, G J Hawkins

Infrared Physics, Vol 31, Issue 3, Pages 237-244 (1991)


A method of designing multi-cavity narrowband filters is presented, which is based on a Tschebysheff optical prototype bandpass filter, the equivalent index concept and the variation of phases through the filter structure. Some design results are given.
