Abstract:
1. A wide passband optical interleaver, comprising: a first optical splitter, having a first output terminal and a second output terminal for just adapting two optical routes; a first optical route of the two optical routes, coupled to the first output terminal; a first optical filter having a transmission coefficient ρ a second optical route of the two optical routes, coupled to the second output terminal; a second optical filter having a transmission coefficient ρ a second optical splitter, having two input terminals for receiving the first optical route and the second optical routes, wherein the transmission coefficients ρ wherein the quantity T is in a range between 0.43 and 0.56 when an operation at 30 dB crosstalk or the quantity T is in a range between 0.32 and 0.7 when an operation at 20 dB crosstalk.
