Abstract

Quasi-phase matching (QPM) employs a short period modulation or grating in the second order nonlinearity, X², to compensate for the phase mismatch of the pump and signal beams in a second order nonlinear process. The main challenge in implementing QPM is to incorporate this X² grating into the waveguide. We are investigating the use of patterned ion implantation of asymmetric quantum wells (AQWs) as a means of achieving this goal
