Effect Of Surface

Electrowetting is a new class of reflective display based on electric field controlled movement of oil/water interface across a hydrophobic layer. The focus of this paper is to fabricate electrowetting cells on a rough hydrophobic surface and to study its effect on kinetics of electrowetting. The surface roughening found effective in two ways in the design and operation of the electrowetting device: (i) It enhances the coating of photoresist (PR) on the hydrophobic surface, which is normally difficult due to low surface energy of Teflon and (ii) the roughness changes the contact angle of the liquid (oil), which in turn changes the electro-optic switching behavior of the device. The kinetics of optical switch was checked by calculating theoretically the white area fraction (WA%), which is a measure of optical switching in electrowetting display by changing the roughness of the hydrophobic surface. The present study showed that the optical performance found to increase with the increase of roughness of the hydrophobic surface.

The Difference

In this work we have studied the electro-optical effect of two types of ferronematic nanoparticles. The first sample doped with magnetic material Fe3O4 and the second sample doped with a ferroelectric material SbSI. The difference in the two types of material that has been vaccinated led to different values of electro-optic properties because of the different susceptibility of materials. We have noticed that the material SbSI was more responsive to the applied electric field due to the nature of the constituent material (electric material) than the Fe3O4 ferromagnetic. The response time for the material SbSI is less than the response time of the ferromagnetic Fe3O4, that led to make the material SbSI best in the optical switch applications.

This paper briefly reviews the nonlinear optical and electro-optical properties and applications of GaAs—AlGaAs multiple quantum wells, all of which are compatible with laser diodes or semiconductor electronics or both. They show large nonlinear absorption and refraction (associated with their strong room-temperature exciton resonances) applicable to all-optical devices. They also show large electroabsorptive effects, some of which are unique to the quantum wells at any temperature, which are so strong that optical modulators can be made with micrometre dimensions. A new class of optical bistability (due to increasing absorption) is also reviewed; combination of this with the electroabsorptive effects enables a new mirrorless optical switch called a Self Electro-optic Effect Device (SEED), which sets a new standard for optical switching energies, with energy densities reduced by a factor of six by comparison to even the best resonant cavity devices.

Electrooptic waveguide technology is suitable for realization of an electro-optic 2x3 switch based on integrated Mach-Zehnder interferometer using polymer material, where ESO of polymeric materials were used. It can provide high performances and it is applicable for all optical switching networks. The relatively low cost technology, easy fabrication process with standard optoelectronic fabrication process and with high degree of integration compared to other technologies make the development of optical switch based on this technology favorable one.
