The effects of pump laser wavelength, power, and direction on optical gain and noise figures in double pass/stage TDFA setups were investigated. For this purpose, four different setups with different pumping types are presented comparatively along the S-band. TDF lengths have been optimized and setups are aimed to be similar. By comparing the pumps with wavelengths of 800, 1050, 1400, and 1560 nm, which are widely used in the literature, the most efficient pump wavelength was determined. The effect of pump direction was investigated by using forward, backward, and bidirectional pumping methods. Then, the setups were compared and the pump power and pumping method were determined with the most efficient wavelength. Finally, the PCE values of all designs were examined and compared.

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.
