查询词典 piezo resonator

The spectral characteristics of the device were measured by an optical spectrum analyzer in a set-up with fiber coupling. A periodically vibrated resonance spectrum was observed with 10 dB contrast and 0.182 nm period. According to the experimental data and the theoretical formula of the ring resonator, transmission loss of 1.7 dB/cm in the ring resonator was obtained.
