ABSTRACT:
A small module for converting an electrical signal to a modulated light signal on an optical fiber comprises a housing, a laser mounted on a laser substrate within the housing, a GRIN lens and an optical isolator downstream from the laser, and a precision capillary for holding an optical fiber downstream from the optical isolator. The relative positions of the laser, lens, optical isolator and fiber are adjusted to maximize light output through the fiber. The optical fiber is sealed to the housing at one point and is free to move axially in the capillary for minimizing mechanical stress on the fiber.
