Abstract

In this demonstration, we experimentally investigate a dual-ring fiber laser architecture to achieve dual-wavelength-tunable by utilizing the self-injected Fabry-Perot laser diode (FP-LD) mechanism. Here, two tunable bandpass filters (TBFs) are utilized in the proposed laser structure to obtain the dual-wavelength with single-longitudinal-mode (SLM). The different mode-spacing of the proposed dual-wavelength fiber laser can also be tuned between 20.8 and 1.3 nm, due to the effective gain amplification of FP-LD. Moreover, we can employ the different FP-LDs with various gain distributions to achieve wide wavelength range tuning.
