The discussion presented in this chapter applies to any electro optic material, any direction of the applied voltage, and any direction of the wave vector. The integration of organic electrooptic materials into silicon photonic, plasmonic, and metamaterial device architectures has led to impressive new performance. An electrooptic effect is a change in the optical properties of a material in response to an electric field that varies slowly compared with the frequency of light. Electrooptic article about electrooptic by the free. The term encompasses a number of distinct phenomena, which can be subdivided into a change of the absorption. These are candidates for electrooptic materials with shg or pockels effects. The optical power of a ld is a function of the injection current, and thus a convenient way to convert an electrical signal into an optical signal is through the direct modulation of the injection current. However, the fabrication processes of these devices are complex and costly, and most of them are usually singlefunctional. The term was coined before optoelectronic, but both terms are.
Here, we demonstrate an allfiber electro optical prototype device with a graphenepmma polymethyl. One of the key limitations for using silicon as a photonic material has been the relatively low speed of silicon optical modulators compared to those fabricated from iiiv semiconductor.
