摘要： An infrared laser source system that combines laser emitters through an optical waveguide. Each emitter is coupled to a port of the optical waveguide and the waveguided signal is combined to provide a spatially combined laser source with a single common exit aperture. The materials used for waveguiding allow the propagation of wavelengths in the infrared. The system can be used for combining multiple laser emitters to increase the total output power and/or for combination of multiple emitters with different wavelength for increased spectral coverage out of the laser system.

摘要： An optical fiber comprising non-silica, specialty glass that has multiple fiber cores arranged in a square registered array. The fiber cores are “registered” meaning that the array location of any fiber core is constant throughout the entire length of the fiber, including both ends. Optical fiber bundles are fabricated by combining multiple multi-core IR fibers with square-registration. Also disclosed is the related method for making the optical fiber.
