Title: Optical modulator
Inventor: MITOMI OSAMU
IPC: G02F1/03
Filed: 1987-03-20
Abstract: PURPOSE:To realize high speed and low driving voltage characteristics by forming a substrate on which the modulating electrodes and light guides of an optical modulator are formed to a small thickness, thereby decreasing the effective dielectric constant of the substrate and equalling the refractive index to signal waves nearly to the refractive index to light. CONSTITUTION:A recess having a width Wv, length Wl and depth (d-h) is formed to the central part on the rear face of the substrate 13 of the optical modulator, which substrate has an electrooptic effect and thickness (d). The slot line type electrodes 15, 16 are formed via a buffer layer 6 on the front of the substrate 13. The spacing between the electrodes is designated as (d) and the length as l. The light guides 4, 5 of a directional coupler are formed in the region 14 of such substrate 13 where the thickness is small. The dielectric constant of the substrate 13 is thus decreased and the refractive index thereof to the signal waves is equalized nearly to refractive index to light, by which the high speed and low driving voltage characteristics are obtd. and the mechanical strength of the substrate 13 in the peripheral part is assured. The optical modulator having excellent productivity and reliability is thus produced.
