New modality of type-I second order nonlinear interaction in bulk AlGaAs Bragg reflection waveguide

Type-I TM ω →TM 2ω phase-matching in isotropic [001]-grown AlGaAs Bragg reflection waveguide is reported. This nonlinear process coexists with type-I TE ω →TM 2ω and type-II TE ω +TM ω →TM 2ω interactions within a spectral window of 17 nm.
