Abstract :
We present a new method to flatten the gain profile of optical amplifiers; inserting an optical isolator in the middle of an Er doped fiber amplifier (EDFA). A flat gain bandwidth of more then 30 nm was experimentally obtained by this method. This is more simple and effective than other gain flattening filter methods.
