Abstract: An optical coupler (60) includes of an optical connector (10) coupled to an optoelectric board (64). An optical fiber (50) is inserted into the optical connector (10). The optical fiber (50) is bent to an angle of approximately 90.degree. inside the optical connector (10). A tip (55) of the optical fiber (50) is substantially perpendicular to the optoelectric board (64) and aligned to an optical region of an optoelectric device (62) on the optoelectric board (64). A portion of the optical fiber (50) outside the optical connector (10) is substantially parallel to the optoelectric board (64). A fiber retainer (30) secures the optical fiber (50) to the optical connector (10).

The optoelectronic device (10) includes a support structure (16) on which an optoelectronic device (12) is mounted. In addition, the optoelectronic device includes a fiber ferrule (13) through which an optical fiber (39) extends. The optoelectronic device (12) and the optical fiber (14) are coated with an overfill material (30).

Abstract: An optoelectronic connector (10) coupled to a fiber ferrule (38) containing an optical fiber (39) and a method for coupling the optoelectronic connector (10) to the fiber ferrule (38). The optoelectronic connector (10) has a base (11) and walls (13, 14, 17, and 18) that form a cavity (19). A semiconductor receiving area (26) extends into a first portion of the base (11) and an interconnect recess (27) extends into a second portion of the base (11). Alignment pins (31) extend from the second portion of the base (11). The optoelectronic connector (10) may be a unitary structure. The fiber ferrule (38) is inserted into the cavity (19) to form an optoelectronic device (30).

Abstract: 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 the index of refraction of the cladding layers (11, 12) to maintain total internal reflection of an input light beam (39). The channel (19) is tapered at an angle (32) to increase beam divergence of the input light beam (39). The beam divergence is increased while the input light beam (39) is reflected through the optically conductive core material (20) from an opening (26) to an exit (27) of the channel (19). The taper of the channel (19) maintains an adiabatic characteristic for the waveguide (10).
