Abstract: A module accommodates multiple superluminescent light emitting diodes, SLEDs, 12r, 12g and 12b. The SLEDs are arranged in an enclosure and output respective light beams to propagate into free space within the enclosure. The individual light beams from the SLED sources are combined into a single beam path within the enclosure using beam combiners 40r-g, 40rg-b. Each beam combiner is realized as a planar optical element, the back side of which is arranged to receive a SLED beam and route it through the optical element to the front side where it is combined with another SLED beam that is incident on and reflected by the front side. The free-space propagating combined beam is output from the module via an optical fiber 42 (or through a window).

Abstract: A light source module comprising a plurality of semiconductor emitters, each configured to emit a beam at a different peak emission wavelength. Each beam is divergent with a more divergent, fast axis and a less divergent, slow axis. First single-axis focusing elements focus the beams from respective emitters in one of the fast and slow axis while the beams remain divergent in the other of the fast and slow axis. A beam combiner based on dichroic mirrors is arranged to bring the beams from the individual first single-axis focusing elements into a common optical axis. A common second single-axis focusing element is arranged to focus the combined beams output from the beam combiner in the other of the fast and slow axis which are then output from the light source module.
