Abstract:

This interim technical report summarizes the first years research efforts to fabricate optical communications fibers that are transmissive between 1 and 12 micrometers. The ultimate objective of this program is to prepare infrared transmitting fibers with losses less than 5 dBkm. In preparing infrared transparent fibers with these losses, we are emphasizing the extrusion into fiber of very pure KCl as this material has demonstrated bulk losses equal to or less than 5 dBkm in the 2- to 6-micrometers region. The primary approach used to meet the program goals, therefore, was the extrusion of reactive atmosphere process RAP grown KCl into 250- to 1000-micrometers-diameter optical fibers. After one year of effort, the best KCl fiber extruded had a loss of 4200 dBkm. This report also summarizes our efforts in fabricating a special infrared fiber prototype device for the detection of pulsed CO2 laser radiation. The prototype device, which is to be used in a battlefield identification friend or foe BIFF application, was successfully field tested in Germany.
