发明名称 INTEGRATED MULTIPLE WAVELENGTH PUMP LASER MODULE
摘要 An integrated multiple-wavelength semiconductor pump laser module (400) operable to generate a plurality of optical wavelength outputs on a single fiber (420) comprising a base layer (400) containing a multi-wavelength laser array (402, 404, 408) and a wavelength multiplexer or combiner (411) unit to produce a single output (402) from a plurality of laser wavelengths (402, 404). The laser array is operable to emit a plurality of wavelengths and each of the laser outputs is substantially oppositely opposed and proximately located to a corresponding combiner (411) input such that laser output enters the combiner (411) input without the use of optical fibers. In one aspect of the invention, the laser array (402, 404, 408) is composed of individual high power DFB lasers. In a second aspect of the invention, the laser array (402, 404, 408) is composed of a single material containing a plurality of lasers fabricated by altering the quantum well widths within the material. In a third aspect of the invention, the laser array (402, 404, 408) and combiner (411) unit are concurrently fabricated within a base layer (410) of semiconductor material.
