摘要：
AlGaAs is one of the most promising integrated quantum photonics material. It has second order nonlinear coefficient which could support spontaneous down conversion (SPDC) process. The phase matching requirement could be achieve by specific designed Bragg reflection waveguide (BRW). In this paper, AlGaAs BRW was designed and simulated. Wavelength relationship of type II SPDC' three photons were calculated. Epitaxy thickness and composition variation effects were also calculated.
