| dc.description.abstract | Optical waveguide devices allow the "capture" of an optical signal and its manipulation to make it modulate, change its path, switch on and off and perform many other functions. One of the desirable parameters for a good electrooptic waveguide device is a high electrooptic coefficient. This allows the optical signal to be manipulated with a low electrical voltage. A material that has a higher electrooptic coefficient than the commercially used LiNbO3 and LiTaO3 is the tungsten bronze crystal BSTN. Strain induced waveguides have been produce in BSTN with propagation losses as low as 1.63 dB/cm (sample 17) and 0.88 dB/cm (sample 20) for TE-and TM-polarization, respectively. Polarization intensity modulators (PIMS) with modulation indices of 78% have been realized. Optical intensity modulation up to 1.5 GHz has been observed, and a 3-dB frequency value of 1.28 GHz has been achieved. | en |
