17 October 2001Design of optical interference filter for DWDM
The specification of DWDM filter becomes higher with the development of WDM technology. The filter must have sharp slope, low insertion loss, qualified pass band width, stop band width and temperature stability. Suitable substrate and coating material should be selected firstly. And multi- cavity F-P filter was adopted to design the narrow band pass filter.
