Gordon, E I

A light source is described comprising semiconductive chips, each chip including a plurality of injection lasers arranged in a linear array, each laser emitting at substantially the same wavelength, all of the lasers emitting light at essentially the same time, and ribbon cables each having coupling portions at one end. Each cable includes optical fibers in a linear array. Each chip is butt coupled to a ribbon cable with one laser being coupled to one optical fiber, the chip and the coupling portions of the ribbon cable being assembled in a unitary package and the other ends of the ribbon cables being arranged to form a two-dimensional array of fibers each emitting light of substantially the same wavelength at its end.
