Multimode circular integrated optical micro- resonators: Coupled mode theory modeling
نویسنده
چکیده
resonator model For modeling purposes, the MR is decomposed into two bent-straight waveguide couplers, represented by the blocks (I) and (II), which are connected to each other by two segments of the cavity. The external connections are provided by straight waveguides. Here we consider only forward propagating modes of uniform polarization. We assume that all elements are linear and that the back reflections inside the couplers and the cavity are negligible. Outside the couplers, the interaction between the constituent waveguides is assumed to vanish. We consider a frequency domain description of the optical field. The vacuum wavelength λ prescribes the real angular frequency ω. Assume that Ns modes of the straight waveguides and Nb bend modes of the cavity are taken into account.

M ay 2 00 5 Multimode circular integrated optical micro - resonators : Coupled mode theory modeling
A frequency domain model of multimode circular microresonators for filter applications in integrated optics is investigated. Analytical basis modes of 2D bent waveguides or curved interfaces are combined with modes of straight channels in a spatial coupled mode theory framework. Free of fitting parameters, the model allows to predict quite efficiently the spectral response of the microresonator...
متن کاملModeling of circular integrated optical microresonators by 2-D frequency domain coupled mode theory
Circular integrated optical (ring or disk) microresonators are increasingly employed as compact and versatile wavelength filters. In this paper, we investigate a two dimensional frequency domain model for these devices, based on spatial coupled mode theory. The microresonators are functionally represented in terms of two couplers with appropriate connections using bent and straight waveguides. ...
متن کاملModeling of grating assisted standing wave microresonators for filter applications in integrated optics
A wide, multimode segment of a dielectric optical waveguide, enclosed by Bragg reflectors and evanescently coupled to adjacent port waveguides, can constitute the cavity in an integrated optical microresonator. It turns out that the device can be described adequately in terms of an approximate coupled mode theory model which involves only a few guided modes as basis fields. By reasoning along t...
متن کاملCompact Wavelength Demultiplexer via Photonic Crystal Multimode Resonators
Wavelength demultiplexers based on photonic crystal resonators are attractive, since they may be realized in very small sizes. However, existing designs have a limitation on the size, since they all require one resonator for each wavelength and these resonators must be separated. As a possible approach to reduce the size further, we show that a single multimode resonator may be used to separate...
متن کاملAdd-Drop and Channel-Drop Optical Filters Based on Photonic Crystal Ring Resonators
Here, we propose an add-drop and a channel drop filter based on two-dimensional photonic crystal all circular ring resonators. These structures are made of a square lattice of silicon rods with the refractive index n1=3.464 surrounded by air (with refractive index n2=1). The broadest photonic band gap occurs at the filling ratio of r/a = 0.17. Two linear defect W1 waveguides couple to the ring....
