Attenuation properties of optical waveguides with a metal boundary

Abstract

Attenuation coefficients have been measured at 6328 Å in liquid waveguides bounded on one side by a metal wall. Provided that the measurements be made on selected samples meeting certain criterions, Ohmic boundary absorption is found to depend on mode order N as (N + 1)2 and waveguide thickness w as w-3, in agreement with theory. © 1973 American Institute of Physics.
