ABSTRACT:
A periodic optical filter for interleaving a plurality of optical signals to provide a multiplexed signal for transmission over an optical fiber is disclosed. The periodic optical filter includes a first optical filter constructed to receive at least two optical signals through an input port to provide at least one filtered optical signal. The periodic optical filter also includes a second optical filter, in communication with the first optical filter, constructed to receive the filtered optical signal from the first optical filter through an intermediate port to provide a multiplexed signal for transmission through an output port. At least one of the optical filters includes an infinite-impulse response filter and at least one of the optical filters includes a finite-impulse response filter. Methods of fabrication and methods of use including the periodic optical filter are disclosed.
