DYNAMICS OF 2-POLARIZATION COUPLING IN A NONLINEAR BRAGG REFLECTOR

Experimental and numerical results of the dynamics of two-polarization coupling in a nonlinear Bragg reflector are presented. A silicon-on-i nsulator (SOI) waveguide is used as the model structure. The effects t hat lattice heating and free-carrier decay have on the dynamics are as sessed in real time. A two-polarization pump-probe technique is used t o monitor the reflectivity simultaneously during the laser-pulse inter action. In addition, the development of three-terminal optical switche s based on two-polarization coupling is discussed.
