“…In most cases, this coupling is negligible. This has been the case for coupled resonators system [33,[45][46][47][48]. However, in very high-Q resonators, the mode coupling (e.g., due to surface roughness) is usually greater than the resonator decay rate.…”

“…We have recently overcome some of the challenges in realizing CROWs and reported experimental measurements of the transmission and group delay in CROWs consisting of highorder weakly coupled polymer microring resonators [12]. In this paper, we describe in detail the fabrication and measurement of the CROWs as well as their transmission and dispersive properties.…”

Abstract-We present measurements of the transmission and dispersion properties of coupled-resonator optical waveguides (CROWs) consisting of weakly coupled polymer microring resonators. The fabrication and the measurement methods of the CROWs are discussed as well. The experimental results agree well with the theoretical loss, waveguide dispersion, group delay, group velocity, and group-velocity dispersion (GVD). The intrinsic quality factors of the microrings were about 1.5 × 10 4 to 1.8 × 10 4 , and group delays greater than 100 ps were measured with a GVD between −70 and 100 ps/(nm · resonator). With clear and simple spectral responses and without a need for the tuning of the resonators, the polymer microring CROWs demonstrate the practicability of using a large number of microresonators to control the propagation of optical waves.

Chains of coupled square dielectric cavities are investigated in a 2-D setting, by means of a quasi-analytical eigenmode expansion method. Resonant transfer of optical power can be achieved along quite arbitrary, moderately long rectangular paths (up to 9 coupled cavities are considered), even with individual standing-wave resonators of limited quality. We introduce an ab-initio coupled mode model, based on a simple superposition of slab mode profiles as a template for the field of individual cavities. Although no loss mechanisms are built in, the model can still help to interprete the results of the former numerical experiments.
