We report on the design, packaging and experimental characterization of a waveguide photodetector monolithically integrated with a 1×4 MMI coupler and a vertically-tapered spotsize converter. The total device consists of an array of 4 photodiodes connected in parallel in order to increase the saturation current. A 3-dB bandwidth of up to 30 GHz was measured. High output power was achieved with approximately 10 dBm at 10 GHz and 7.5 dBm at 20 GHz. From 1-dB compression measurements at 10 GHz and… CONTINUE READING
