Abstract:
1. A process for optically switching an incoming optical signal having a header address bit in a data packet of the incoming optical signal, the process comprising (a) injecting the data packet and an input optical control signal into a laser device, said optical control signal having a first wavelength λc and the data packet having a second wavelength λd and said laser device having both locked and unlocked states at the first wavelength λc and the second wavelength λd; (b) optically processing the header of the data packet by setting the laser device at the locked state or the unlocked state at the wavelength λc and by maintaining the state of the laser device for processing of the packet; (c) said state of the laser device being based upon the combination of a trigger of a first optical intensity in the control signal and the address bit of the data packet; and (d) said state of the laser device being maintained by a trailer of a second optical intensity of the control signal; (e) selectively enabling the transmission of the data packet based upon the state of the laser device.
