Title: Waveguide type optical modulator
Inventor: MIYAZAKI TOKUICHI
IPC: G02F1/035
Filed: 2001-05-09
Abstract: PROBLEM TO BE SOLVED: To provide an optical waveguide modulator which can reduce disturbance of modulation caused by an acousto-optic effect in a low frequency band, can obtain flat modulation characteristics without disturbance over the wider band, and can further enhance the electric reflection characteristics. SOLUTION: In the optical waveguide modulator, an optical waveguide 12 is formed in a substrate 11 consisting of the ferroelectric substance, such as LN or LT. A signal electrode 13 is formed on the optical waveguide 12, and common electrodes 14 and 15 are formed adjacently to the signal electrode 13. The optical waveguide modulator modulates the optical phase of the wave which propagates the optical waveguide 12 in accordance with the electric signal applied between the electrodes 13 and 14 (15). The optical waveguide modulator changes width of the signal electrode 13, and spaces between the signal electrode 13 and the common electrodes 14 and 15 along the optical propagation direction, and does not change the equivalent refractive index of the electric signal in the optical propagation direction of the optical waveguide 12.
