Abstract
Optical inputs to photonic switches may incorporate a polarization controller in order to change the polarization of the input signal to a pre-determined polarization for operation with the silicon photonics. A last stage of components of the polarization controller may overlap with a first input switching stage. A polarization controller that overlaps with the first stage of the switch input may provide lower insertion loss and power consumption for the photonic switch.
