摘要

我们制作了一种具有两个耦合盘的拉伸应变InGaAsP-InP量子阱(QW)激光器，发射波长为1.5μm。对于半径为10μm、输出波导宽度为2 μm的微磁盘，室温下连续波阈值电流为24mA，模式间隔为2 nm和5.3nm，对应于对称模式和非对称模式的分裂以及经度模式空间。主模在115mA时，波长为1522nm，峰值强度比背景高25dB。

Tensile-strained InGaAsP-InP quantum-well laser with coupled disks emitting at 1.5µm

We fabricate a tensile-strained InGaAsP-InP quantum-well (QW) laser with coupled two disks, emitting at 1.5μm. For a microdisk with radius of 10μm and a 2-μm-wide output waveguide, a continuous-wave (CW) threshold current is 24mA at room temperature and the mode intervals of 2 and 5.3nm are observed, corresponding to splitting of symmetric and asymmetric modes, and longitude mode space. The peak intensity of main mode is 25dB higher than the background with the wavelength of 1522nm at 115mA.
