Abstract:
1. A laser-induced optical wiring apparatus comprising: a substrate; a first light-reflecting member and a second light-reflecting member, which are provided on the substrate separately from each other; an optical waveguide provided on the substrate, the optical waveguide optically coupling the first light-reflecting member and the second light-reflecting member to form an optical resonator; a first optical gain member provided across a portion of the optical waveguide; and a second optical gain member provided across a portion of the optical waveguide separately from the first optical gain member, wherein the first optical gain member and the second optical gain member forms a laser oscillator along with the first light-reflecting member and the second light-reflecting member, wherein: when the first and second optical gain members are activated, the laser oscillator performs laser oscillation; when a gain of one of the first optical gain member and the second optical gain member is changed by an input signal, a total gain of an optical path extending between the first light-reflecting member and the second light-reflecting member is changed to change a laser oscillation state of the laser oscillator formed by the first optical gain member and the second optical gain member; and a change in the laser oscillation state is detected by the other of the first optical gain member and the second optical gain member.
