SC205 - Integrated Electronic Circuits for Fiber Optics

Monday, 07 March
13:30 - 16:30

Short Course Level: Advanced Beginner


Y. K. Chen; Retired Bell Labs​, USA

Short Course Description:

High speed electronics is a critical enabler in the advanced transceivers to power fiber-optic networks from residential access, enterprise networks, high performance computers and data centers. In this class, we will review the basic functions of high speed lightwave circuits in optical terminals, with emphasis on physical layer transceiver electronics. The basic functions and architectures of these circuits will be reviewed. The high speed IC technologies and their implementation of these important high bit-rate digital, analog and mixed-mode electronic solutions for common on-off digital signals to complex modulated communication waveforms will be presented.

The presentation materials include receiver front-ends including trans-impedance amplifiers and limiting amplifiers, clock-data recovery circuits including phase locked loop and digital phase detectors, SERDES such as electrical time-domain multiplexers, de-multiplexers and transmitter circuit such as driver amplifiers. Methods to enhance the performance and bandwidth are illustrated with examples from literature, along with results showing the current state of the art.  Today's advanced high capacity optical transponders at 100Gbps and beyond utilize very complex signaling and detection techniques. The requirements and characteristics of the related data converters technologies (ADC, DAC) to implement these complex modulation formats will be reviewed.
