Abstract
We propose and experimentally demonstrate a tunable and switchable multi-wavelength fiber laser (MWFL) employing a semiconductor optical amplifier (SOA) and twin-core photonic crystal fiber (TC-PCF) based in-line comb filter. An in-line Mach-Zehnder interferometer is configured by splicing a section of TC-PCF between two SMFs, and used as an optical comb filter in MWFL. The lasing modes are switched by adjusting a polarization controller in the fiber ring cavity, and the change is reversible. The proposed fiber laser can operate with two different lasing wavelengths spacing with a signal-to-noise ratio (SNR) over 28 dB. In addition, we also demonstrate a tunable multi-wavelength fiber laser operation by applying temperature changes to TC-PCF in the multi-channel filter.
