Paper Abstract

A Variable Optical Attenuator (VOA) in a simple structure is introduced using the basic principles of internal reflection. The proposed configuration includes a special trapezoid prism-film system which allows a light beam incident twice upon the bottom face and once upon the top face ofthe prism. As a result, a VOA having greater than 20dB dynamic range and less than 0.5 dB Polarization Dependent Loss (PDL) has been demonstrated experimentally.
