Second-harmonic generation of blue light from [112]-oriented III-V antiresonant waveguide heterostructures

Second-harmonic generation of blue light by the nonlinear interaction of two counter-propagating transverse electric-polarized fundamental fields in a [112]-oriented (Al,Ga)As/GaAs antiresonant waveguide is demonstrated. Theoretical calculations of the visible output power for given fundamental inputs are shown to agree with experiment. Our results show that GaAs-based materials may offer another alternative for the development of blue/green light-emitters. (C) 1996 American Institute of Physics.
