摘要: Six single–multi–single (SMS) mode fiber-based Mach–Zehnder Interferometers (MZI) with different spooling radii are demonstrated as spatial filtering elements for multi-wavelength laser generation. Free spectral range (FSR) tuning of the output generated is realized by alternating between six MZIs, which have macro-bending losses. Additional FSR also changing radius two-mode step index fiber section within MZI setups from 80 mm to 30 mm, giving an 0.89–0.99 nm. All outputs show high stability over a test period 100 min. The proposed lasers highly suitable various microwave photonics applications field such signal source generation and photonic filtering.
