Paper Abstract

A fiber optic variable attenuator using a dichroic polarizer sheet illuminated by a heating beam is described. The light absorbed by the polarizer induces a thermal lens, which allows one to control the amount of light to be coupled into an optical fiber. Some experiments demonstrating the thermal lens action are presented.
