We propose the incorporation of graphene to integrated coupled resonator waveguides and side-coupled integrated spaced sequence of resonator devices to enable reconfigurable operation. The key element to achieve this is a tunable silicon graphene Mach–Zehnder interferometer (MZI) that acts as an equivalent variable 2 $\times$ 2 coupler, where the value of its coupling constant is changed by varying...
In this paper, an experimental demonstration of the apodization of coupled resonator optical waveguide (CROW) devices through the longitudinal offset technique is presented for a 3 racetracks CROW device and compared against the uniform case.
In this paper we present a method to linearize the group delay response of a type I Coupled Resonator Optical Waveguide (CROW) structure. The method can be used for the design of low ripple chromatic dispersion compensators on pass-band CROW. Different chirping procedures have been studied, similar to the ones employed in Fiber Bragg grating devices, and several apodization functions, to reduce the...
