Continuous Tunability in Three-Terminal Coupled-Cavity Lasers.
01 January 1986
The continuous tunability of various coupled-cavity semiconductor lasers has been investigated. Monolithic etched groove and cleaved coupled cavity (C3) geometries are included. Using a novel method to modulate the laser currents, appreciable tuning ranges have been achieved (~8angstroms) without mode hops. Also, for the first time, tuning of a laser with no amplitude variation is illustrated. A tuning range of 1-4angstroms with
