Abstract :
Implantation of an InGaAsP MQW structure with 4 MeV N-ions at room temperature and at 200°C results in absorption recovery times < 10 ps. High-temperature implantation improves the post-implantation absorption modulation by up to 20%, due to dynamic annealing. This makes implantation at high temperature an interesting technique for the fabrication of ultrafast non-linear optical devices.
