It shows that the active channel with sizeable optical gain and a substantial increase of the refractive index are promising for the realization of activewaveguide tunable laser.
研究表明,室温下有源沟道具有较大的光增益和折射率增量,有望实现可见波段的可调谐有源光波导激光器件。

These devices have opticalwaveguide structure, moderate doping level and active layer thickness.
该器件带有光波导结构并具有适当掺杂和有源层厚度。
