dependence of the effective refractive index on the refractive index of the environment. Using a result of waveguide perturbation theory, the geometrical characteristics of the core of the circular waveguide that maximize the sensitivity of the system are determined. Both single and dual core configurations are considered.
26 Feb 2009 modes of the resonator, and the dissipations of the resonator and the atom. We also show that a generalized critical coupling condition, that the single-photon transmission at the output of the waveguide goes to zero on resonance for a matched system, holds for the full coupled waveguide-ring
Abstract -A rigorous mode matching technique is used to analyze the dielectric ring resonators loaded in waveguide and on top of substrate. Variation of several lowest order modes' resonant frequencies as a function of structure parameters is presented and is helpful for optimization of spurious modes separation.
Ring-resonator theory. For the sake of further understanding, consider the typical abstract setting of a horizontally coupled circular microresonator as sketched in Figure 1.4. Two straight waveguides are evanescently coupled to the cavity. For ``well confined'' modes of the straight waveguide and cavity, one can expect that
Critical to understanding how an optical ring resonator works, is the concept of how the linear waveguides are coupled to the ring waveguide. When a beam of light passes through a wave guide as shown in the graph on the right, part of light will be coupled into the optical ring resonator.

Model of a single ring resonator with one waveguide light in the ring resonator filter are incorporated in the attenuation constant, the interaction can be described by the matrix relation: (. Et1. Et2. ) = ( t ?. ??? t. ?. )( Ei1. Ei2.
microring resonator, as a function of the coupling gap. Theoretical analysis of the coupling loss on small-radius ring resonators is not trivial. Near the strong coupling region between the ring and the bus waveguide, in addition to the primary bus and ring waveguide modes, many other radiation or leaky modes are also
Southworth at first took the theory from papers on waves in dielectric rods because the work of Lord Rayleigh was unknown to him. This misled him somewhat; some of his experiments failed because he was not aware of the phenomenon of waveguide cutoff frequency already found in Lord Rayleigh's work. Serious
We generalize an earlier published analysis of critical coupling in a single-ring resonator waveguide system [Electron. Lett. 36, 321 (2000) ] to multiple-ring resonator all-pass and channel-dropping filter structures. The fundamental analytical relationships among coupling coefficient, internal loss, and oscillation frequency
