A Low Power High Speed CMOS Based Optical Receiver for Communication Network Based Applications

The advancement of communication based technology and the growth of the internet traffic have continuously driven the fast evolution of the intelligent networks based applications. As compared to the traditional optoelectronic switch based devices, all the optical transreceiver provides high throughput, rich routing functionalities, and excellent flexibility for rapid signal exchange in optical networking based systems. Among various optical switches, the thermal actuated ring switching devices provides the advantages of high accuracy, easy actuation, and reasonable switching speed for better data communication. However, when this device is used in the system scale up, it may encounter certain issues related to fabrication error, non accurate wavelength. A low-power multi-band RF receiver including a multi-band low-noise amplifier (LNA) based on the IEEE 802.15.4 standard for sensor node applications response, and large terminal numbers in the control circuit. A 12-channel parallel optical receiver front-end amplifier array design and realization in a low cost 0.18 μm CMOS technology. The integrated circuit system has been designed, simulated and demonstrated with a decent performance having free spectral range (FSR) equal to 1.5 nm at 1534 nm and very accurate wavelength modulation to 0.3 nm within 0.01 nm fluctuations for thermal actuated ring type optical switch.
