Lumerical MODE simulations of a novel photonic integrated circuit design using cross coupling and a 3 x 3 single waveguide double ring resonator
Abstract
Photonic Integrated Circuits (PICs) have been of interest in research due to their inherent efficiency in signal transmissions. With that, this study continues Daquioag and Dingel’s exploration of a novel PIC design involving cross coupling, a 2 x 2 coupler, and a 3 x 3 coupler through simulations in Lumerical MODE. With two versions of the design differing in coupling length (one at 3 microns and the other at 7 microns), the simulations present differences between the two in terms of light transmission, phase shift and response, free spectral range (FSR), and chromatic dispersion. These results carry further implications for the potential applications of this particular PIC design.
