Abstract
A housing for a device has first and second segments with opposed adjacent surfaces fixedly connected to each other. The first segment fixedly carries a semiconductor optical source for emitting a linearly polarized optical beam in the general direction of the longitudinal axis of the housing. The second segment fixedly carries an optical fiber element having an end face positioned along the longitudinal axis to intercept the optical beam and a linear optical polarizer. The first and second segments are fixedly positioned relative to each other along the longitudinal axis and in a plane perpendicular to the longitudinal axis so the optical beam, as incident on the end face, has a predetermined geometry and position. The second segment is fixedly positioned about the longitudinal axis so the optical beam, as incident on the end face, is in a predetermined power range.
