Abstract :
A monolithic pair of InP/Ga0.47In0.53As/InP metal-semiconductor-metal photodetectors with a strained Al0.1In0.9P cap layer was fabricated. The dual photodetectors exhibit closely matched frequency characteristics. Effective laser intensity noise suppression and a beat signal enhancement in 100 MHz balanced heterodyne detection was experimentally demonstrated
