<p>Using a semi-conductor laser amplifier 1 in reflection, an optical switch is achieved which can be applied as either an AND/OR, or a NAND/NOR, logic gate. The amplifier 1 responds to an optical input switching signal and the logical characteristics of its response can be controlled by selection of the drive current to the amplifier 1. The switch finds application in optical logic or communication systems.</p> |
