Monolithically-Integrated Quantum Dot Optical Power Monitor

A monolithically-integrated quantum dot optical power monitor is presented. The device is a laser diode whereby a fraction of the laser emission is coupled into a photodiode section via a multi-mode interferometer. The resulting photocurrent is used to assess the applicability of photodiode designs.
