Summary:
We study time-domain properties of outputs from two-dimensional (2D) cavity microlasers theoretically and experimentally. The gain competition of resonant modes is numerically simulated by the Schrödinger-Bloch model that describes nonlinear interaction between the light field and a two-level gain medium. The simulations reveal mode-pulling phenomena that generate beat oscillation of nearby resonant modes and eventually lead to the locking of their frequencies for higher pumpings. Carrying out experiments for semiconductor 2D microlasers, we observe slow modulation of 4-10 MHz in the output signals, which is attributed to the beating of nearly degenerate resonant modes.
