What we believe to be the first demonstration of an edge-emitting Bragg reflection waveguide laser is reported. The laser utilized InGaAs quantum wells emitting at 980 nm, with Al(x)Ga(1-x)As core and claddings. The lasing mode is centered in a low-index core with a width of 700 nm, hence providing a large mode volume with strong discrimination against any modes other than the fundamental photonic bandgap mode. Single-transverse mode operation is observed with thresholds as low as 157 A/cm(2). The propagation losses of the mode were measured for the first time and found to be 11.4 cm(-1).
我们报道了一种边缘发射布拉格反射波导激光器,据信这是该激光器的首次演示。该激光器采用在 980nm 处发射的 InGaAs 量子阱,具有 Al(x)Ga(1-x)As 芯层和包层。激光模式集中在具有 700nm 宽度的低折射率芯层中,从而提供了大的模式体积,并对除基本光子带隙模式之外的任何模式具有很强的选择性。观察到阈值低至 157A/cm(2)的单横模运转。首次测量了模式的传播损耗,发现为 11.4cm(-1)。
