Monolithically Integrated Wavelength Converter for Intra Data Center Routing Applications
A wideband wavelength converter based on cross gain modulation has been demonstrated by using a monolithically integrated semiconductor optical amplifier and 12 channel distributed feedback lasers. Error free operation unicast wavelength conversion of 10 Gb/s non return to zero ON OFF keying data payload has been demonstrated with 3 dB power penalty and around 0.5 dB extra penalty for transmission over 2 km single mode fiber for intra data center application. Performance of the wavelength converter multicasting operation of two channels has also been assessed by controlling the distributed feedback lasers. Experimental results show 4.5 dB power penalty after multicast wavelength conversion. The wavelength conversion of uni /multi casting operations would provide a compact, low power, and low cost solution for wavelength routing based intra data center networking applications.
