Abstract

DWDM thin film filter phase properties including phase shift and group delay are analyzed in this paper. According to the dispersion control requirement, a method of group delay ripple compensation on transmission is forwarded. A high reflective film system is overlapped before the transmission light from the filter; the total group delay ripple is decrease with the counteraction ofhigh reflective films on contrast to the DWDM filter.
