We present a monolithically integrated optical receiver fabricated with standard silicon processing technology for fiber-wireless IEEE 802.11 wireless local area network (WLAN) applications. The receiver contains a silicon avalanche photodetector and a transimpedance amplifier and has up to 5.6-GHz photodetection bandwidth. Using this integrated optical receiver, transmission of 54-Mb/s WLAN signals...
We demonstrate a 60-GHz fiber-wireless downlink using a balanced subharmonic optoelectronic mixer based on a silicon avalanche photodiode (APD) pair fabricated with standard 0.25- bipolar complementary metal–oxide–semiconductor technology. Conversion efficiency of this new type of optoelectronic mixer is 11 dB better than that of the previously reported single APD mixer. We achieve downlink...
In this paper, LED driver and optical receiver for 650-nm plastic optical fiber (POF) applications are designed and implemented using 0.5-mum CMOS technology. In LED driver, modulation current has to be arranged in 3 to 4-mA to meet eye protection regulations in visible red wavelength (650-nm). To apply for low cost POF applications, simple and low cost LED driver is proposed. LED driver is designed...
We demonstrate a fiber-fed 60-GHz self-heterodyne system using a self-oscillating harmonic optoelectronic mixer (SO-HOM) based on a Si avalanche photodetector (APD) fabricated with 0.18 μm standard complementary metal-oxide-semiconductor (CMOS) process. The proposed SO-HOM consists of a CMOS-compatible APD and a feedback electrical loop for self-oscillation. It simultaneously performs photodetection...
