Generation of Coherent Multi-Wavelength Lights with Hundreds GHz Frequency Spacing from an Injected Fiber Laser with an Intracavity Tunable Micro-Ring Resonator

Abstract

Coherent multi-wavelength lights with 133 and 266 GHz frequency spacing are successfully generated from a new fiber laser scheme. The phase-locking characteristics are examined through the auto-correlation contrast as well as the down-converted beating linewidth.
