Abstract
An integrated optical modulator comprising: an insulating substrate (14); an insulating ridge extending upwardly from the substrate (14), the ridge comprising an electrically conducting layer (16) within the ridge above the substrate (14); an optical waveguide (18, 19) positioned on the ridge and extending down through the ridge to the conducting layer (16); an electrical contact (24, 25) on the optical waveguide; a travelling wave electrode (20, 21) on the upper surface of the substrate (14); and, an electrically conducting air-bridge (22, 23) extending from the electrical contact (24, 25) to the travelling wave electrode (20, 21).
