Abstract:Fast-tunable filters play a crucial role in various applications including tunable lasers, high-speed optical communications, microwave photonics, and spectroscopy. However, current fiber Fabry-Peŕot tunable filters (FFPTF) predominantly rely on piezoelectric transducers (PZT), which struggle to achieve rapid modulation with high repeatability and accuracy owing to hysteresis and creep effects. In this study, we demonstrate an FFPTF with high linearity (>0.99) and an approximate 1 MHz dynamic tuning frequency … Show more
