| Abstract: | Using coupled mode theory, the transfer functions on both through and drop channel waveguides of polymer microring resonator filters are calculated, and the effects of coupling coefficients and loss on transfer functions are analyzed. The resonance wavelength, free spectrum range, quality factor, FWHM, and fineness of micro-ring resonator filters are derived, and the characteristics of filters varied with different structure parameters, such as the radius of the ring and the effective index, are also analyzed. |

| Keywords: | polymer micro-ring resonator filter free spectrum range fineness coupling coefficient |
