Description

technical field

[0001] The invention relates to optical communication technology, in particular to a narrow-band thermo-optic tuned Fabry-Perot filter with flat top and steep band-edge response. Background technique

[0002] In optical communication networks, tunable filters are used to form various demultiplexers to separate the multiplexed light; applying this tunable filtering technology to lasers and detectors can realize dense wavelength division multiplexing It is an important tunable light source and receiver in multiplexing (DWDM); the key device of the new generation of all-optical network, the optical add-drop-demultiplexer (OADM), can also be composed of this filter. It can be seen that the tunable filter has become an indispensable and important device in the all-optical network and DWDM system. The application of the filter in the optical network includes the differential detection of channel light. In addition to the narrow band and tunable filter, it is also ...
