Abstract
An optical amplifier having two erbium doped fiber coils and a pump laser diode is described. A tunable optical power splitter is used for variably splitting the optical pump power for the laser diode between the two erbium doped fiber coils, and variable tilters can be used for correcting the gain tilt of the amplifier. The variable splitter and the tilters can include thermally tunable Mach-Zehnder interferometers.
