  • Integrated bi-directional axial gradient refractive index/diffraction grating wavelength division multiplexer
    Patent number: 6011884
    Abstract: A wavelength division multiplexer is provided that integrates an axial gradient refractive index element with a diffraction grating to provide efficient coupling from a plurality of input optical sources (each delivering a single wavelength to the device) which are multiplexed to a single polychromatic beam for output to a single output optical receiver.

  • Integrated bi-directional gradient refractive index wavelength division multiplexer
    Patent number: 6011885
    Abstract: A wavelength division multiplexer integrating a dispersive element having a gradient refractive index with optical lenses to provide efficient coupling from a plurality of input optical fibers (each delivering a plurality of discrete wavelengths to the device) which are multiplexed to a single polychromatic beam for output to a single output optical fiber.
