Abstract

An optical processing device includes: a light source that outputs second light having a first polarization state or a second polarization state in synchronization with the pulse timing of the pulse of first light; a first nonlinear medium that controls the polarization state of the first light pulse in accordance with the polarization state of the second light pulse, using a nonlinear effect; and a separator that outputs the first light pulse from the first nonlinear medium selectively to a first output path or a second output path in accordance with the polarization state controlled by the first nonlinear medium. In this device, the first nonlinear medium uses the nonlinear effect to compensate the level of each first light pulse output selectively to the first output path or the second output path by the separator, with each first light pulse receiving the energy of the second light pulse.
