A unitary retention piece or collar (20, 25, 32) is provided for mounting and retaining an optical fiber (10, 30) in an optoelectronic device (40). The collar (20, 25, 32) is cast or molded onto an optical fiber (10, 30) to provide a means for mounting the fiber (10, 30), typically on a semiconductor substrate, for alignment with other devices such as laser diodes and photodetectors. The collar (20, 25, 32) can be cast or molded onto the glass fiber (12) with coating (14) and buffer (16) layers in place, or a portion of the buffer layer (16) can be stripped off so that the molded collar (20, 25, 32) extends over both the buffered fiber and a portion of the stripped glass fiber (12). The collar (20, 25, 32) can be molded in any desired external shape for mating with a clip, retainer, socket, or housing to secure the fiber to the substrate or optoelectronic device package (40). |
