Telluride glass single mode fiber for mid and far infrared filtering

Abstract : For the detection of an exo-planet on which signs of life are possible, one needs to develop single mode fibers working in the mid-IR. Telluride glasses are known for their large transparency in the mid and far infrared region, but the drawback is their high crystallization tendency during the reshape process. In this paper, a new method of preform preparation is explored and used to develop small core (20 µm) tellurium based glass fibers. They transmit light from 3 to about 16 µm with minimum losses near 7.9 dB·m−1. Moreover, this fiber presents single mode guidance at 10.3 µm.
