Abstract
A multiwavelength Er-doped fiber (EDF) laser was proposed and experimentally demonstrated using a nonlinear optical loop mirror (NOLM) and a twin-core fiber-based Mach–Zehnder interferometer (TCF MZI). A total of 40 lasing wavelengths around the wavelength of 1560 nm with an average signal-to-noise ratio (SNR) of 28 dB and 30 lasing wavelengths around the wavelength of 1530 nm with an average SNR of 20 dB were achieved when the EDF length was 6 and 2 m, respectively. To the best of our knowledge, this is the first time that multiwavelength oscillations have been obtained in the wavelength range of 1530 nm by using a NOLM. The wavelength spacing is ∼0.19 nm which is determined by the TCF MZI. In addition, the effects of the pump power and the state of polarization on the performance of the multiwavelength EDF laser were investigated.
