Abstract:
An interleaver comprising: a beam splitter to split an input optical beam into a first sub-beam and a second sub-beam; an etalon coupled to receive the first sub-beam, the etalon having a reflective surface and an air gap, the reflective surface to reflect signals passed through the air gap; and a non-linear phase shifter coupled to receive the second sub-beam, the phase shifter modifying a phase of the second sub-beam, the modified phase of the second sub-beam causing constructive and destructive optical interference between the reflected first sub-beam and the reflected second sub-beam to cause a first subset of signals from the input optical beam to be directed to a first port and the second subset of signals from the input optical beam to be directed to a second port.
