ABSTRACT:
A wide passband optical interleaver includes a first optical splitter, having a first output terminal and a second output terminal. A first optical route is coupled to the first output terminal. A second optical route is coupled to the second output terminal. A delay is coupled on the second optical route. A second optical splitter having two input terminals is receiving the first optical route and the second optical route. A plurality of optical filter respectively having transmission coefficients ρiis coupled to the first optical route and the second optical route. The transmission coefficients ρiare determined by satisfying a desired quantity of effective group delay ratio T, defined asT=∑i⁢Si⁢1-ρi1+ρi,where⁢⁢Si⁢⁢is+1⁢⁢or-1.where Siis +1 or −1.
