Lecture
This lecture covers the analysis of the Q factor and Bit Error Rate (BER) in the context of photonic systems and technology. It explains how to minimize BER by finding the optimal threshold level, discusses the Q factor as a measure of signal quality, and explores the relationship between Q factor and BER. The lecture also delves into the interpretation of eye diagrams, the impact of noise on signal quality, and methods for estimating BER using the signal-to-noise ratio. Practical examples and graphical representations are used to illustrate these concepts.
