Furthermore, the overlay considered here is assumed to be optically transparent in the investigated wavelength range, or in other words the waveguide is considered lossless. Last, the presented analysis holds as long as the cladding 40 A. Cusano et al. r3 surrounding medium (nout) r2 overlay (n3) cladding (n2) core (n1) r1 Fig. , for SRI lower than the cladding RI. For higher SRIs, another model is required to take into account the coupling between the core mode and the radiation modes for the four-layer waveguide.
7 dB, which is mainly due to the fiber-to-waveguide coupling at the input and output ports of the device. 2 Microresonator Sensors Made in Polymers with Functional Chromophore Dopants 17 Fig. 5 Chemical structures of the chromophores used in this work.

Electron beam provides nanometer scale resolution, and microring resonators with critical feature size of 100–200 nm are readily achievable. E-beam bleaching can be carried out by a standard scanning electron microscope (SEM) with a pattern generator. Without the need of expensive high resolution photomasks, different designs of microring resonator devices can be generated easily with electron beam bleaching.
