VIGO Photonics products

Most current applications use VCSELs in the IR spectrum. VCSEL device is a laser die based on a semiconductor material and comprised of epitaxial layers grown on n-type GaAs or InP substrates. The epitaxy is performed by molecular beam epitaxy (MBE) or metal-organic chemical vapor deposition (MOCVD). The VCSEL structure, which is only a few micrometers thick, includes Fabry-Perot (F-P) cavity (resonator) with several active quantum wells as well as top and bottom DBRs (Distributed Bragg Reflector).

PC-9-AF1×1-TO39-NW-90 is uncooled IR photoconductive detector based on sophisticated HgCdTe heterostructure for the best performance and stability. In order to make this detector immune to unwanted optical fringing effects, VIGO developed anti-fringing technology (internal modification of substrate’s surface) and successfully applied it. This results in the fringing 10 – 40 times smaller compared to the standard IR detector.
