摘要：

Integrated-optic double-ring resonators with a wide free spectral range (FSR) of 100 GHz are fabricated using GeO2-doped silica waveguides with a high relative refractive index difference (Delta) of 1.5%, The resonators are composed of two ring resonators comprising small ring waveguides with radii of 1.75 and 2.0 mm, The double-ring resonator module exhibited a wide FSR of 98.0 GHz, a finesse of higher than 138, a low crosstalk of less than -11.7 dB, and a low insertion loss of 6.1 dB. The measured FSR of 98.0 GHz is wider than any previously reported ring resonator composed of optical waveguides.
