            Abstract : 
A compact integrated all-optical wavelength converter based on an asymmetric Sagnac loop is demonstrated. We show that a 40-Gb/s nonreturn-to-zero data signal can be converted over the entire C-band employing an asymmetric Sagnac loop. Compared to the back-to-back configuration, a receiver sensitivity power penalty of less then 2.1 dB is measured for both up- and down-conversion.
