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

Starting from the desired modal field we solve for the supporting waveguide refractive index structure within a semiconductor diode laser. Specifically we analyze the problem of maximizing far-field on-axis intensity and discuss the practical aspects of waveguide design.

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.
