We report on the possibility to detect laser emission of microdisk laser having diameter of 24 μm with an active region based on InGaAs/GaAs quantum well-dots using a waveguide photodiode (100x4000 μm) with a similar active region. A photocurrent of ~ 10 μA was obtained under a continuous-wave laser operation, injection current of 20 mA and a distance between the facets of the microlaser and photodiode of about 100 μm. The photodiode’s sensitivity was estimated to be ~ 9 μA / 10 μW.
