Abstract:
An integrated gradient refractive index wavelength division multiplexer device comprising:(a) means for accepting a plurality of optical beams of different wavelengths from a plurality of optical sources, said means including a planar front surface onto which said plurality of optical beams are incident;(b) a dispersive element comprising a gradient refractive index for combining said plurality of optical beams into at least one multiplexed, polychromatic optical beam and operatively associated with said planar front surface;(c) a coupler subsystem affixed to said dispersive element and comprising (1) a homogeneous index boot lens having a planar front surface onto which said at least one multiplexed, polychromatic optical beam from said dispersive element is incident, (2) an axial gradient refractive index collimating lens affixed to said homogeneous index boot lens, and (3) a planar back surface from which said at least one multiplexed, polychromatic optical beam exits, operatively associated with said axial gradient refractive index collimating lens; and(d) means for outputting said at least one multiplexed, polychromatic optical beam to an optical receiver, said means including said planar back surface.
