Abstract
The abrupt increase in the traffic demand requires the need of ultrafast advanced optical networks that are capable of achieving the throughput ranging from hundreds Gb/s to several Tb/s. Advanced transmission technologies such as DWDM have been intensively researched to provide huge transmission capacity and flexible network operation. All-optical switches, which are not limited by the speed of electronic devices, have a large number of applications in high-speed optical communication system. All-optical switching operation is obtained in a DFB structure containing optical Kerr-like media.1 To date, we have demonstrated all-optical set-rest switching2 and thresholding operation3 in a strip-loaded DFB waveguide. Also, we have discussed the dependence of switching power on the control wavelength4 and polarization5.
