Abstract
An optical switch with a waveguide used as a detector is disclosed. The switch can be used for circuit or packet switching. The waveguide is used to tap off a fraction of the input signal going into the switch. The waveguide then sends the tapped off signal to a local electronic control to decide if switching is necessary or not. This is determined by within the local electronic control associated with the switch. The switch is set or reset based on information in the electrical representation of the signal which reaches the local electronic control. The switch can be used with continuous input signals as well as data packet input signals. By spacing the timing of data in the header differently than in the data in the 'data' portion of a signal, extremely high bandwidth available in pure optical communications can be maintained.
