Abstract
An optical modulation deviceincludes a supporting bodyincluding a pair of groovesand a protrusionbetween the grooves, a ridge parincluding a channel type optical waveguide capable of multi mode propagation, a first side plate partA formed in a first side of the ridge part, a second side plate partB formed in a second side of the ridge part, a first adhesive layerA adhering the first side plate partA and the supporting body, a second adhesive layerB adhering the second side plate partB and the supporting body, and a third adhesive layerC adhering the ridge partand the protrusion. The devicefurther includes a first electrodeA provided on a side faceof the ridge part on the first groove side, and a side faceand an upper faceof the first side plate part, and a second electrodeB provided on a side faceof the ridge partin the second groove side, the second grooveand a side faceand an upper faceof the second side plate partB. The first electrodeA and the second electrodeB apply a modulation voltage modulating light propagating in the channel type optical waveguide.
