A wavelength-switchable quadruple-wavelength erbium -doped fiber laser using linear-cavity configuration is proposed and demonstrated experimentally at room temperature. A Sagnac loop with a length of polarization -maintaining fiber acts as a comb filter and a broadband chirped fiber grating with low reflectivity acts as the flat reflective mirror in the resonant cavity. On the basis of the polarization hole burning effect, after adjusting a polarization controller, the laser can switch flexibl y to output six different modes from single-wavelength to quadruple-wavelength. All of lasing lines with narrow linewidth of less than 0.3 nm have the optical signal-to-noise ratio of more than 30 dB.Erbium-doped fiber laser, Switching, Chirped fiber grating.

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.
