  • Wavelength division multiplexed coupler
    Publication number: 20030063853
    Abstract: The invention provides an optical coupling system having first and second back-to-back GRIN lenses each having an input and an output end face, an optical filter element disposed between the first and second back-to-back GRIN lenses, an input optical fiber tube having two optical fibers therein adjacent to and optically coupled with the first of the back-to-back GRIN lenses, an output optical fiber tube having an optical fiber therein adjacent to and optically coupled with the second of the back-to-back GRIN lenses, wherein an inwardly facing end face of the output optical fiber tube and the output end face of the second of the back-to-back GRIN lenses are non-parallel to each other for reducing coupling losses. The optical coupling system is supported in glass holding tubes.
