Abstract:
1. A back-reflection reduction device between a support structure containing a plurality of optical waveguides for transmitting light in a predetermined wavelength range and a bulk media, the support structure having a substantially flat end face at which the optical waveguides terminate, the optical waveguides being substantially perpendicular to the end face, the back-reflection reduction device comprising: a window having an inner side and an opposing outer side, the inner side being affixed over substantially its entire area to the flat end face; wherein a gap exists between the window outer side and the bulk media, the gap providing an index of refraction substantially equal to unity in the predetermined wavelength range of the light transmitted through the optical waveguides; and wherein the window has a refractive index that is substantially identical to that of the optical waveguides in the predetermined wavelength range of the transmitted light.
