Description

This lecture covers the principles of coherent detection in optical systems, focusing on the interference between the signal and local oscillator. It explains the advantages of homodyne detection over normal detection, emphasizing the enhancement of the signal-to-noise ratio. The lecture discusses the role of shot noise and thermal noise in the detection process, providing insights into optimizing detection performance.
