ABSTRACT:
An optical switching apparatus comprises an optically resonant system (3, 12) and a pulse source configuration (1, 2) to direct first and second pulses (P1, P2) of optical radiation into the resonant system, the first pulse (P1) being configured to produce a coherent excitation of the resonant optical system so as to change its optical characteristics and the second pulse (P2) being of a phase to thereafter de-excite the coherent excitation produced by the first pulse. According to the invention, a device (13, 34) driveable externally of the resonant system such as an optical amplifier or a laser, maintains the coherence of the excitation produced by the first pulse until de-excited by the second pulse. The optically resonant system may comprise an optically responsive medium (3) which is capable of being switched into a state of coherent resonance or a resonant cavity.
