  • Practical Uses and Applications of Electro-Optic

    The phase modulator is the simplest electro-optic modulator.Here, an electric field is applied along one of the crystal's principal axes. 3 Light polarized along any other principal axis experiences an index of refraction change, hence an optical path length change, that is proportional to the applied electric field. The phase of the optical field exiting from the crystal therefore depends on ...

    In this paper we describe the principles of operation as well as the fabrication and testing steps of an all-organic waveguide modulator. The modulator comprises an SU-8 core and an electro-optic host-guest polymer cladding. The polymer properties are tuned in order to achieve single mode operation. We used direct-write laser lithography in two steps for the preparation of the devices.
