Abstract
Beam steering of a 10. 6‐μm guided‐wave mode in an electro‐optic GaAs thin‐film waveguide is observed. The deflection angle increases linearly with increasing voltage and interaction length. A switching time of about 60 nsec has been obtained and is limited by the detector response. This technique has been used to obtain more than 12% amplitude modulation of a CO2 laser by applying only 50 V to an ∼20‐μm‐thick GaAs thin‐film waveguide having a total interaction length of 0. 5 cm.Keywords
