Parameters-dependent nonlinear absorptions in InGaN/GaN MQW and GaN film

The optical nonlinearities of an InGaN/GaN multiple quantum well (MQW) and a GaN film were experimentally investigated by using femtosecond Z-scan method in this paper. It was observed that the InGaN/GaN MQW displays a nonlinear saturable absorption (SA) effect and the nonlinear absorption coefficie...
