Two metal-semiconductor-metal (MSM) photodetectors are integrated monolithically with coplanar waveguide transmission line. By illuminating this structure with CW light and taking the difference between the two detectors, 9-10 dB noise cancellation was achieved. Another demonstration of noise cancellation is then proposed. Measurements show that the noise can be reduced by 3 dB without degrading the signal to noise ratio.
