Abstract:
1. A system for conversion or amplification using a quasi-phase matched nonlinear optical wave mixing, the system comprising a first radiation source configured for providing a pump radiation beam, a second radiation source configured for providing a signal radiation beam, and a bent structure configured for receiving the pump radiation beam and the signal radiation beam, wherein a radiation propagation portion of the bent structure is made of a uniform nonlinear optical material and wherein 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 being substantially inverse proportional with the linear phase mismatch for the nonlinear optical wave mixing, an outcoupling radiation propagation portion configured for coupling out an idler radiation beam generated in the bent structure.
