OPTICAL FIBER ASSEMBLY AND OPTICALLY COUPLED DEVICE PACKAGE INCLUDING SAME

摘要

OPTICAL FIBER ASSEMBLY AND OPTICALLY COUPLED DEVICE PACKAGE INCLUDING SAME An optically-coupled device package including a housing containing an optical device further includes an optical fiber assembly which comprises an optical cable with a support sleeve on its end. The support sleeve comprises a body with an axial opening therethrough and has a plurality of holes near a first end. The optical cable includes a first portion comprising a protective coating overlying an optical fiber, and a second portion comprising an optical fiber extending from said coating. The cable enters the first end of the sleeve and nodules integral with the protective coating extend into the plurality of holes. In one embodiment, the optical fiber is sealed to the inside of the sleeve through a solder window provided through the side of the sleeve. The second end of the sleeve extends through an aperture in said housing and is aligned to the device therein. The invention also includes a method for making such a fiber assembly which comprises inserting the optical cable into a first end of the sleeve, forming nodules integral with the protective coating which extend into the plurality of holes. The method may comprise sealing the optical fiber to the inside of the sleeve through a solder window in said sleeve. Fabrication of an optically-coupled device package further comprises inserting the fiber assembly through an aperture in said housing and aligning said fiber with the optical device therein.
