摘要

Continues efforts to develop low loss flexible waveguides, to transmit mid IR laser energy for minimal invasive surgical and diagnostic procedures, have been carried out by us and other groups in this area. We have introduced sulfide dielectric films coated over an Ag reflecting layer as another potential solution. The metal sulfides used, have high transparency in the infra red spectrum and their thickness can be tailored to minimize the attenuation over a selected wavelength range. The high refractive index contrast of the two metal sulfide materials enable to produce multi layer hollow waveguides. These waveguide will have low attenuation in both straight and bent conditions, low sensitivity to coupling and to surface roughness and a broad wavelength range. The straight lowest loss measured at 1.55 μm for a 1,000-μm bore Ag/CdS/PbS/CdS HGW was 0.06 dB/m. This loss is three times less than that measured for a single layer Ag/CdS coated HGW at 1.55μm. A theoretical simulation applying the same conditions showed the same pattern with a good potential for improvement.
