We present a multi-segment photonic crystal coupled cavity laser device on GaSb with a microstructured internal photodiode. This monolithically integrated power monitor is added as a third segment to a coupled cavity laser and is separated from the active device by six rows of two-dimensional photonic crystals, acting as highly reflecting mirrors. There is no additional fabrication step needed to integrate this feature into the coupled cavity laser, resulting in a highly integrated laser device of only 800 µm length. The device with lasing wavelength around 1955 nm shows single mode emission over a tuning range of as large as 16 nm and exhibits output powers of up to 9 mW.
我们展示了一种基于GaSb的多段光子晶体耦合腔激光器件，其带有微结构化内部光电二极管。这种单片集成的功率监测器作为第三段被添加到耦合腔激光器中，并通过六排二维光子晶体与有源器件隔开，这些光子晶体起到高反射镜的作用。将此功能集成到耦合腔激光器中无需额外的制造步骤，从而得到了一种长度仅为800 µm的高度集成激光器件。该器件的激射波长约为1955 nm，在高达16 nm的调谐范围内呈现单模发射，输出功率高达9 mW。
