Fabrication and characterisation of electro-optic Fabry-Pérot modulators containing a poled crosslinked polymer are described. Electro-optic modulation as large as 38% in reflection has been obtained with a low cavity finesse figure of 3.4 and a driving voltage of 88 V rms. The corresponding electro-optic coefficients r13 and r33 were measured at 633 nm to be 11 pm/V and 36 pm/V using angle-tuning of the Fabry-Pérot etalon. The thermo-optical coefficient of 1.0×10-4 K-1 of the polymer film was also measured. A lower-bound measure of the bandwidth of these devices was observed at a detection system limit of 1 MHz. © 1993.
