- Abstract
- We investigate the efficiency of an optical intensity modulator based on an electrically tunable LiNbO3 reflection grating. Assurning a grating coupling coefficient and the waveguide propagation loss, waveguide length is varied to find its effect on the modulator slope efficiency and the device capacitance. With the low propagation loss of the LiNbO3 waveguide, a very efficient optical intensity modulator can be achieved for a low frequency (similar to 1 GHz) as long as the requirement for the grating coupling coefficient is satisfied.
