摘要
An apparatus and a method by which polarization components may be processed separately, for example, to enable a polarization beam splitter (PBS) or a switch. In one embodiment, the apparatus includes: first and second Mach-Zehnder interferometers, each Mach-Zehnder interferometer having input and output optical couplers and two internal optical arms, each optical arm connecting one output of the input optical coupler to a corresponding input of the output optical coupler, the output optical coupler of the first Mach-Zehnder interferometer being the input optical coupler of the second Mach-Zehnder interferometer, wherein the input optical coupler of the first Mach-Zehnder interferometer is configured to transmit one polarization component of the light to two of the outputs thereof and to transmit a different polarization of the light to substantially only one of the outputs thereof in response to receiving said light at an input thereof.
