Paper Abstract

A novel integrated optical modulator based on electrooptical control of Bragg gratings has been developed and fabricated. The modulator can provide both the shift of the central wavelength and the change of a shape of the spectral response of Bragg gratings. The frequency modulation (FSK) of optical signals with frequency deviation of 25 GHz was experimentally demonstrated using this modulator. It is suggested not only central wavelength, but the optical spectrum shape can be used for modulation of optical signals with information content. A novel type of optical modulators will provide addition flexibility and possibility of using FSK formats in combination with optical spectral code division multi access (OCDMA) and gives an opportunity of new network architectures with simple optical processing on the level of addressing and routing.
