摘要
A narrowband, widely tunable filter based on a whispering gallery mode LiNbO3 cavity with 10 GHz free spectral range is proposed and demonstrated. The filter operates at 1.55 mum with 30 MHz bandwidth and can be electro-optically tuned at 10 GHz in the linear regime with approximately 40 MHz/V tuning rate. With this filter, we have demonstrated 12 dB fibre-to-fibre insertion loss and 30 mus tuning speed.
