摘要：

Ultrashort pulses complicate the frequency conversion in a nonlinear crystal,where group velocity mismatch becomes the main obstacle due to dispersion.We present a design for group velocity compensated second harmonic generation in a modulated nonlinear structure,embedded in a liquid crystal box.In this structure,nonlinear crystals act as sources of signal and liquid crystals compensate for group velocity mismatch originating from nonlinear crystals.There are the advantages of the flexible,controllable birefringence of liquid crystals.Meanwhile,a method calculating the parameters of this type of structure is presented.To make it clear,an example is provided.Furthermore,the structure can also be shaped as a waveguide to support integration into other optical devices,applicable to all-optical processing systems.
