—All-optical 2R-regeneration based on polarization rotation in a single semiconductor linear optical amplifier is experimentally demonstrated. An extinction ratio (ER) improvement of 15 dB has been obtained for an input ER of 5 dB under static operation. With a degraded input signal, a receiver-sensitivity improvement of 3 dB at a bit error rate of 10 9 was(More)
During the last years we have pioneered several new concepts for 2R optical regeneration. Two of these concepts, an active 2x2 multi mode interference (MMI) coupler and a Mach Zehnder interferometer with a regular semiconductor optical amplifier in one arm and an active 1x1 MMI in the other arm, have been fabricated as photonic integrated circuits. A third(More)
