ABSTRACT:
An optical alignment structure is described for coupling the output of a laser diode to an optical fiber. The structure includes a rigid outer block which holds the laser diode in tight thermal contact, The block defines a cavity within which there is an optic axis along which the output from the diode flows. A coupling lens set is held within the cavity by a lens holder cantilevered within the same via a flex connection. Adjustment screws are provided extending through the block to adjust the position of the lens holder relative to the optic axis. The end of the optical fiber within which the radiation is to be coupled is held in position by a ferrule which is adjustable longitudinally along the optic axis. A selected position for the same along the axis is maintained via a set screw.
