Abstract

A polarization-insensitive tunable attenuator using a liquid crystal retarder and two birefringent optical wedges is fabricated and demonstrated. It features an attenuation tuning range of larger than 35 dB, a residual loss of less than 0.8 dB, a broad spectral width of 1.1 - 1.65 micrometers , low polarization sensitivity, and no mechanical moving parts.
