Dual wavelength fibre laser with tunable channel spacing using an SOA and dual AWGs
In this paper, we propose and demonstrate a dual wavelength fibre laser (DWFL) based on the use of an inhomogeneously-broadened semiconductor optical amplifier (SOA) gain medium as well as two arrayed waveguide gratings (AWGs) together with two optical channel selectors (OCSs) and a broadband fibr...

| Summary: | In this paper, we propose and demonstrate a dual wavelength fibre laser (DWFL) based on the use of an
inhomogeneously-broadened semiconductor optical amplifier (SOA) gain medium as well as two arrayed
waveguide gratings (AWGs) together with two optical channel selectors (OCSs) and a broadband fibre Bragg
grating (FBG) to generate dual wavelength output at variable channel spacings. The widest spacing obtained
from the DWFL is 12.21 nm, while the narrowest spacing is 1.16 nm. The DWFL has good stability with only
minor power fluctuations of less than 2 dB and a side mode suppression ratio (SMSR) of approximately 38.5 dB
with fluctuations of less than 0.5 dB |
