Thickness monitoring of optical filters for DWDM applications.


A method for thickness monitoring and turning-point prediction during deposition of narrow band pass optical filters (NBPF) for dense-wavelength-division-multiplexing (DWDM) applications is proposed. The method is based on a recurrent approach, with relative transmittance .tting, and includes partial coherence and monochromator bandpass e.ects. We show that… (More)
