Author(s): G. G. Sarate

Paper Abstract

Voltage tunable optical communication modulators using optical filter are now the most important and advanced integrated devices in the field of integrated optics. The modulator with central wavelength 1.33um is studied which works on wide range of wavelength. The tunable wavelength can be achieved by changing voltage across electrodes. the design of voltage tunable optical modulator using asymmetric directional coupler filter modulator with strip of waveguide made up of Titanium in diffused in Lithium Niobate for various fabrication parameters for central wavelength 1.33mm is studied. Matrix method, which is faster, is used for computation of effective index. Based on this method the critical coupling length is investigated. The work focused on studies of the directional coupler filter modulator at wavelength 1.33mm .The response with maximum transfer efficiency. the effectiveness of device by reducing coupling length and device length is studied.
