Longitudinal-mode control in integrated semiconductor laser phased arrays by phase velocity matching [PDF]
, 1984 The spectrum of semiconductor laser arrays with separate contacts is investigated. It is demonstrated that the individual laser currents can be selected such that the array operates in a single longitudinal mode in contrast to the multimode nature of its

Phase-locking characteristics of coupled ridge-waveguide InP/InGaAsP diode lasers [PDF]
, 1984 The phase-locking characteristics of two coupled, ridge waveguide InP/InGaAsP diode lasers emitting at 1.2 µm were investigated experimentally. The phase locking of the lasers was verified by the observation of phase-locked modes (supermodes) in the ...

High-efficiency, single-longitudinal-mode ring fibre laser
Electronics Letters, 2005 A novel single-longitudinal-mode erbium-doped ring fibre laser is proposed and demonstrated experimentally. It combines a narrow-linewidth fibre Bragg grating (FBG) with several Mach-Zehnder mode filters (MZF) to obtain a single-frequency emission. It yields a power conversion efficiency of 16%.
