Abstract
A system for conversion or amplification using quasi-phase matched nonlinear optical wave-mixing comprises a first radiation source for providing a pump radiation beam, a second radiation source for providing a signal radiation beam, and a bent structure for receiving the pump radiation beam and the signal radiation beam. The radiation propagation portion of the bent structure is made of a uniform nonlinear optical material and the radiation propagation portion comprises a dimension taking into account the spatial variation of the nonlinear optical susceptibility along the radiation propagation portion as experienced by radiation travelling along the bent structure for obtaining quasi-phase matched nonlinear optical wave-mixing in the radiation propagation portion. The dimension thereby is substantially inverse proportional with the linear phase mismatch for the nonlinear optical process. The system also comprises an outcoupling radiation propagation portion for coupling out an idler radiation beam generated in the bent structure.
