| Research Abstract |
Microwave circuits have been prepared onto LiNbO3(LN) electro-optic crystal substrate. Integration of microwave circuits with the EO modulator has been realized. Microwave 90-degree hybrid was directly prepared onto the LN substrate, to create those two modulation signals from a single input signal. The coupler circuit was designed with miniaturized configuration of one third in area compared to the conventional structure. The SSB light modulator using this miniaturized coupler circuit was fabricated and its workability was confirmed by the experiments. Additionally, the rat-race circuit as a 180-degree hybrid was also considered to be prepared on LN substrate and integrated with EO modulator.
