The microring resonator was fabricated by using CMOS compatible processes with 1 μm wide waveguides and 400 μm in radius,which has a high Q factor up to 20,000 and a Free spectrum range of 0.5 nm.A measurement scheme was proposed by using the resonator,a single-wavelength light source and an optical power meter,which has higher system sensitivity than the conventional measurement setup by detecting resonance wavelength shifts with an optical spectrometer.Finally,the resonator was applied to dete...
