Abstract
With increasing demands for wireless data transfer, networking, graphics, and high-speed communications using the Internet, 10 Gb/s and 40 Gb/s are expected to become the standard fiber-optic operating speed for the future datacommunication and telecommunication systems. In this paper, photoreceivers using PIN/HBT are investigated for 20 Gb/s and 40 Gb/s OEIC applications. A 20-Gb/s and a 40 Gb/s short wavelength PIN/HBT photoreceivers (PIN_TZ_1L4 and PIN_TZ_1L1_L) are presented. Implemented using fT = 60 GHz InGaP/GaAs HBT technology, PIN_TZ_1L4 has simulated 3-dB bandwidth of 17.4 GHz with 43.3 dB Ω gain using a 25-μm diameter PIN photodetector. PIN_TZ_1L1_L using inductor peaking technique has simulated -3 dB bandwidth of 33.5 GHz with 49.3 dB Ω gain using a 10-μm diameter PIN photodetector. By using multi-channel Wavelength Division Multiplexing (WDM) receiver, we are designing two-dimension receiver arrays (2×2) that are capable of receiving data rate of 80 Gb/s or higher. Fabrication and measurement of the new designs are currently under way.
