Terahertz generation by optical rectification in uniaxial birefringent crystals
Terahertz generation optical rectification uniaxial birefringent crystals Optics
2012/5/28
The angular dependence of terahertz (THz) emission from birefringent crystals can differ significantly from that of cubic crystals. Here we consider optical rectification in uniaxial birefringent mate...
Theoretical investigation of polarization-insensitive data format conversion of RZ-OOK to RZ-BPSK in a nonlinear birefringent fiber
