Abstract
In this paper we presented the modeling, design of a millimeter wave (MMW) photonic modulator operating at high Giga-Hertz frequency, i.e. 94GHz. Our approach combines high quality factors (Qs) photonic microdisks with nonlinear properties of electro-optic (EO) material at the present of applied millimeter wave to achieve optical modulation. The high Q values and strong field densities associated with WGMs in microdisk resonators result in the enhancement of the nonlinear interaction of optical fields with a material that exhibits coherent attributes, even with weak millimeter waves. The coupled mode theory (CMT) is applied to incorporate the nonlinearity of EO material in the optical analysis. In the simulations, two EO materials, LiNBO3 and GaAs, are considered and designed to realize the MMW photonic modulation. In addition, carefully design and analysis is taken by using rigorous electromagnetic (EM) algorithm to accurately determine EM field in the MMW resonator, which will provide maximum modulation.
