Second harmonic conversion enhancement in 2-D planar photonic crystals
Two dimensional (2D) periodic texture in a thin GaAs semiconductor waveguide is used to dramatically enhance the second harmonic conversion efficiency of infrared laser radiation incident on the structure from above. A square lattice of through-holes was etched into a 140 nm thick layer of GaAs supp...
