The first results on the use of the hot stamping technique for fabricating a diffraction
grating on the end face of the polycrystalline IR fibers (PIR-fibers) were reported in before. This
paper presents a continuation of the research in this direction. In particular, we look into the
possibility of using the hot stamping technique for fabricating antireflection subwavelength
structures on the end faces of the silver halide PIR-fibers.
