Abstract :
Discovery Semiconductors has developed a 45 GHz "dual-depletion InGaAs-InP photodetector". The PIN operates at -3 V reverse bias and has minimum responsivity of 0.5 A/W at 1.3 and 1.55 /spl mu/m wavelength. The ripple factor is less than /spl plusmn/1 dB for a wide band of frequencies, DC to 45 GHz. The salient feature of the PIN is an on-chip co-planar waveguide output for proper impedance matching. The combination of optical, microwave, and digital functions on the same chip is a technology that has significant potential for commercial applications such as ethernet fiber local area networks and optical communications systems.
