Abstract
Abstract A package housing (52) for hermetically enclosing an optoelectronic component (56) is formed with a tubular extension (54) which extends outwardly from a wall (52a) of the housing (52) and communicates with the interior of the housing (52) through an opening (52h) formed through the wall (52a). The axis of the extension (54) is self-aligned with a light propagating (transmitting or receiving) portion (56a) of the component (56) as mounted in the housing (52). A piece of optical fiber (60) has an end portion (60c, 60d) which is fittingly retained in the extension (54), and extends substantially from an outer end (54a) of the extension (54) to the light propagating portion (56a) of the component (56). A metal jacket (60b) is stripped from a portion (60c) of the optical fiber (60) which fits in a small diameter outer portion (54b) of the extension (54), whereas a portion (60d) of the optical fiber (60) covered with the jacket (60b) fits in a larger diameter inner portion (54c) of the extension (54). A cap (64) is fixed to the outer end (54a) of the extension (54), and has a central hole (64a) through which the optical fiber (60) extends, to constitute an integral connector (62). The optical fiber (60)is automatically self-aligned with the light propagating portion (56a) of the component (56) by insertion of the end portion (60c, 60d) of the optical fiber (60) into the extension (54).
