Abstract

Abstract

Bandwidth enhancement in phased laser arrays is explained using small-signal frequency-domain analysis on coupled mode rate equations. In-phase modulation of asymmetric arrays produces bandwidth enhancement in agreement with experimental measurements.

Abstract

Abstract

When operated in the coherently coupled regime, microcavity laser diode arrays have an electrical signature in their differential series resistance. The mechanism of this effect is explained using a complex coupling coefficient in coupled mode rate equation theory.
