Mounting of optical fibers to integrated optical chips.

摘要

A fiber carrier (34) provides an effective coupling means between a cleaved facing surface of an optical fiber and a light port in a mounting surface (22) of an integrated optical device. Both the fiber carrier (34) and the integrated optical device (12) have an anisotropic thermal expansion property along the same known optic axis and both are substantially similar in magnitude to each other. The fiber carrier (34) is positioned with the integrated optical device (12) so that both the carrier optic axis is parallel to the device optic axis and so that an auxiliary surface (46) of the carrier is parallel to the device mounting surface (22). The optical fiber (40) is then bonded to the fiber carrier (34) so that the plane of the optical fiber cleaved facing surface lies in the plane of the carrier auxiliary surface. The carrier auxiliary surface (46) is finally bonded to the device mounting surface (22) so that the optical fiber cleaved facing surface is placed in registration with the light port in the device mounting surface.
