摘要：An optical system (22) contains an optical waveguide (10) having cladding layers(11, 12) defining a channel (19) that is filled with an optically conductive core material (20).The index of refraction of the optically conductive core material (20) is greater than theindex of refraction of the cladding layers (11, 12) to maintain total internal reflection ofan input light beam (39). The channel (19) is tapered at an angle (32) to increase beamdivergence of the input light beam (39). The beam divergence is increased while the inputlight beam (39) is reflected through the optically conductive core material (20) from anopening (26) to an exit (27) of the channel (19). The taper of the channel (19) maintains anadiabatic characteristic for the waveguide (10).
