<p>A device (1690) generates an optical output (7) that is dependent on two optical inputs. In an embodiment, two inputs are provided and the amount of energy, the direction of its emission, or a port through which the input energy is emitted is determined by whether optical energy is applied at both inputs or only one of the inputs. The device may be used, for example, to provide the function of a gate.</p> |
