The wavelength-switchable and stable erbium-doped fiber laser (EDFL) based on a Mach–Zehnder interferometer (MZI) was designed and experimentally demonstrated. For the proposed fiber laser, a bitaper MZI was manufactured using extrusion splicing photonics crystal fiber (PCF) and single-mode fiber to generate the comb filter effect. In the experiment, an erbium-doped fiber with a length of 3 m was used as the laser gain medium in the cavity. The laser threshold was 95 mW, and a laser output of 1563.06 nm was obtained. Single-wavelength tunable lasing from 1561.22 to 1563.34 nm with a minimum tuning space of 0.08 nm was realized. The power fluctuation was lower than 3.261 dB, and the signal-to-noise ratio (SNR) exceeded 28.535 dB. By tuning the polarization conditions, dual-, triple-, and quadruple-wavelength lasers with power fluctuations lower than 0.23, 2.94, 6.77 dB, respectively, were realized in the experiment. The 3 dB linewidth for the laser was less than 0.06 nm. The results indicate that single-, dual-, triple-, and quadruple-wavelength-tunable lasers can be realized using the proposed fiber laser.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
