INTERACTION OF TWO DIFFERENT WAVEGUIDE MODES IN KERR MEDIA PHOTONIC CRYSTAL

Buddhi Rai, Physics, Western Michigan University,

We present a waveguide method of molding and localizing light energy by an optical material composed of periodic arrays of dielectric media known as a 2D photonic crystal, that may have potential applications for transmitting information on micro or nanoscale in photonics technologies. The waveguide modes interact with the localized modes on Kerr nonlinear features in the system, which are investigated using the methods of the classical theory of light-matter interaction and modern numerical simulation techniques. The main focus is on modeling interaction of two different frequency waveguide modes, both within a stop band of photonic crystal band spectrum, incident into the waveguide channel and interacting with each other through the resonant excitation of modes on off-channel and in-channel features of Kerr nonlinear media. The results include transmissivity for modes of the two-frequency model that reproduces interesting physical properties of optical bistability and induced transparency.
