Superluminescent Diode Module

An optical source module comprising:

• a housing defining an enclosure of free space;
• first, second and third sources selected from the group of superluminescent light emitting diodes (“SLED”) and laser diodes (“LD”) wherein the first, second and third sources are arranged in the enclosure to emit first, second and third beams having respective first, second and third center wavelengths, the first, second and third beams propagating in the free space along first, second and third beam paths;
• a first beam combiner arranged in the enclosure to receive the first beam and the second beam, and to combine them into a combined beam extending in the free space along a combined beam path;
• a second beam combiner arranged in the enclosure to receive the combined first and second beam and the third beam, and to combine them to form a combined beam into the combined beam path;
• first and second anamorphic prisms arranged in the combined beam path prior to the optical output port which cooperate to provide beam shaping of the combined beam;
• and
• an optical output port arranged to receive the combined beam and to output the combined beam from the housing.
