Abstract
High sensitivity interferential electro-optical modulator. The invention concerns an interferential electro-optical modulator. This modulator contains a Mach-Zehnder integrated interferometer in which each interferometer arm (24, 26) is overlapped by an electrode (40, 42), itself surrounded by two lateral electrodes (44, 46, 48, 50) to uniformize the electrical field crossing through each arm perpendicular to the face of the electro-optical crystall on which it is formed. Application to the detection of accoustic waves and low voltage measurement.
