Frequency-Domain Description of Semiconductor Mode-Lock Lasers
This talk presents a frequency-based theoretical framework utilizing multimode laser theory to explain the diverse dynamical behaviors of semiconductor mode-lock lasers by analyzing mode competition and multiwave mixing through a generalized Alder's equation, with direct connection to the semiconductor bandstructure.
Overview
There are much recent research activities involving semiconductor mode-lock lasers, motivated by applications ranging from spectroscopy to conventional and quantum coherent communication. This talk discusses a frequency-based theoretical approach to describing the vastly different dynamical behaviors. Central to the approach is mode competition and multiwave mixing treated with multimode laser theory. Results are understood in terms of frequency locking of coupled oscillators, describable by generalized Alder’s equation. Understanding with direct connection to bandstructure comes from consistent treatment of linear and nonlinear optical responses of quantum-mechanical electron-hole polarizations.
