Description
This lecture delves into the physics of photonic semiconductor devices, starting with the derivation of the oscillation relaxation frequency for laser diodes. It covers vertical cavity surface emitting lasers, high-beta nanolasers, and quantum cascade lasers. The discussion includes the temporal behavior of laser diodes, the steady-state solutions to the coupled equations, and the small-signal frequency response derived from harmonic analysis. Specific features of high-beta nanolasers, such as power-dependent measurements of the second-order autocorrelation function, are explored. The lecture also touches upon the applications of high-beta nanolasers in biophotonics and photonic integrated circuits.
