摘要	A multi-wavelength distributed Bragg reflector (DBR) semiconductor laser is provided where DBR heating elements are positioned over the waveguide in the DBR section and define an interleaved temperature profile that generates multiple distinct reflection peaks corresponding to distinct temperature dependent Bragg wavelengths associated with the temperature profile. Neighboring pairs of heating elements of the DBR heating elements positioned over the waveguide in the DBR section are spaced along the direction of the axis of optical propagation by a distance that is equal to or greater than the laser chip thickness b to minimize the impact of thermal crosstalk between distinct temperature regions of the interleaved temperature profile.
其他摘要	提供了一种多波长分布式布拉格反射器（DBR）半导体激光器，其中DBR加热元件位于DBR部分的波导上方，并定义交错的温度分布，产生多个不同的反射峰，对应于与温度相关的不同温度相关的布拉格波长。个人资料。位于DBR部分中的波导上方的DBR加热元件的相邻成对加热元件沿光学传播轴的方向间隔开等于或大于激光器芯片厚度b的距离，以最小化热的影响交错温度分布的不同温度区域之间的串扰。
