We present the first light source module that is realized with RGB superluminescent LEDs in a compact 14‐pin butterfly housing for speckle‐free display applications. The module provides a free‐space output with collimated RGB beams that are colinearly aligned having 10 mW output power per color. [ABSTRACT FROM AUTHOR]

We analyze the influence of intrinsic polarization alignment on image quality and axial resolution employing a broadband 840 nm light source with an optical bandwidth of 160 nm and an output power of 12 mW tailored for spectral-domain optical coherence microscopy (SD-OCM) applications. Three superluminescent diodes (SLEDs) are integrated into a 14-pin butterfly module using a free-space micro-optical bench architecture, maintaining a constant polarization state across the full spectral output. We demonstrate superior imaging performance in comparison to traditionally coupled-SLED broadband light sources in a teleost model organism in-vivo ., Competing Interests: Marcus Duelk (FEP), Stefan Gloor (FEP), Jean Dahdah (FEP), José Ojeda (FEP) are collaborators of EXALOS AG.
