A theoretical analysis of the coherent external cavity semiconductor laser ensemble is presented. The theoretical analysis lends insight to the limits of stability of the coherent ensemble for different spatial filter designs and indicates difference

Reduced-confinement tapered waveguide antennas are shown to produce reductions of >35% in the transverse far-field beam divergence for radiation emitted from GaAlAs slab waveguides, resulting in far-field beams as narrow as 8.2 degrees full width at

Five diode lasers that each have one facet antireflection coated were fiber coupled into an external cavity and operated as a coherent ensemble by the use of a spatial filter placed at the Fourier plane of the cavity. The resulting output was shown t

Monolithically integrated reduced‐confinement antennas are shown to produce reductions of >35% in the far‐field beam divergence for radiation emitted from single‐mode GaAlAs slab waveguides, yielding far‐field beams as narrow as 8.2° FWHM al

A design is presented of a high-power diode laser system that may be mass produced at minimum cost. The system consists of: an array of semiconductor lasers (stacked bars each with a multiplicity of stripe lasers); a mass-produced array of collimatin

An integrated optical system that produces a flat-phase output wavefront, independent of phase and power variations along the input wavefront, is proposed for use at GaAs laser wavelengths. A basic module of this system is shown in Fig. 1. Developmen

Tapered-waveguide antennas reduce the far-field divergence of beams emitted from integrated-optical waveguides. Previously, we presented preliminary results on reduced-confinement GaAlAs antennas,1 which, unlike horn antennas, are compatible with two

A reduced‐confinement GaAlAs tapered‐waveguide antenna has been demonstrated. This device, produced by means of a novel growth technique using molecular‐beam epitaxy, employs a longitudinal variation in the refractive index and thickness of the

A historical account of the work on lasers at MIT Lincoln Laboratory is presented. Highlighted are the efforts that led to the co-invention of the semiconductor laser and the Laboratory's later role in establishing the feasibility of GaInAsP/InP semi
