Method and apparatus for adjusting tilting and level of optical signals
摘要:
Pump energy with a wavelength which is below the wavelength of an optical signal is fed into a transmission section from a pump laser via a coupler. The received optical signal is attenuated with increasing pump power with signals having higher frequencies being more strongly damped.
