J. Chow et al., MULTIWAVELENGTH GENERATION IN AN ERBIUM-DOPED FIBER LASER USING IN-FIBER COMB FILTERS, IEEE photonics technology letters, 8(1), 1996, pp. 60-62
Simultaneous continuous wave multiwavelength operation of an erbium-do
ped fiber laser has been demonstrated using two types of recently deve
loped in-fiber grating comb filters. The lasing wavelengths and linewi
dths were determined by the comb filter, which was inserted in a ring
cavity with a single inhomogenously broadened gain medium.
