The authors present a Fabry-Pérot étalon using an electro-optic (EO) polymer material as the nonlinear medium. The two electrodes used to apply voltage across the EO polymer include an indium tin oxide electrode outside the étalon cavity and a low-absorption indium oxide electrode inside the étalon cavity. High finesse (∼234) and a low insertion loss (∼4dB) have been obtained. An isolation ratio of 10dB and ∼10% modulation depth at 200kHz with 5V applied voltage have been achieved. These results indicate that EO polymer étalons are promising as spatial light modulators for information technology.
