Extinction Ratio and Power Penalty

This lecture covers the concepts of extinction ratio, power penalty, intensity noise, and timing jitter in photonic systems. It explains how the extinction ratio affects system performance and the power penalty calculation. Additionally, it delves into intensity noise, its impact on optical power fluctuations, and the timing jitter's influence on sampling time fluctuation. The lecture also discusses the measurement of receiver performance using a bit error rate tester and the sources of power penalty during signal propagation. Finally, it explores the impairments of optical receivers, including noise, signal-related issues, and timing jitter, emphasizing the importance of continuous monitoring of the eye diagram for performance evaluation.
