Claim 0:
1. An optical source module comprising: a housing defining an enclosure of free space; first, second and third superluminescent light emitting diode, SLED, sources arranged in the enclosure to emit first, second and third SLED beams having respective first, second and third wavelength ranges, the first, second and third beams propagating in the free space along first, second and third beam paths; a laser diode source arranged in the enclosure to emit a laser beam to propagate in the free space; a first beam combiner arranged in the enclosure to receive the first SLED beam and the second SLED beam, and to combine them into a combined SLED beam with a spectrum including the first and second wavelength ranges and 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 SLED beam and the third SLED beam, and to combine them to form a combined SLED beam with a spectrum including the first, second and third wavelength ranges into the combined beam path; a third beam combiner arranged in the enclosure so that the laser beam is combined with one of the SLED beams so that the laser beam and the SLED beams propagate along the combined beam path; and an optical output port arranged to receive light along the combined beam path and to output the light from the housing.
