Coherent Perfect Absorption and Transmission of Light

This lecture covers the concept of coherent perfect absorption and transmission of light waves through interferometric cancellation of backscattering. The instructor presents experimental realizations and optimizations for achieving perfect absorption and transmission, including the use of anti-reflection structures and degenerate cavities. The lecture also discusses the application of these techniques in complex scattering systems and the successful experimental implementations. Additionally, the lecture explores how nature has solved similar problems, such as enhancing absorption and achieving complete transmission and reflection. Collaborative works and future research directions are also highlighted.
