Patent ID: 7656928

Claim:
A laser-induced optical wiring apparatus comprising: a substrate; an optical waveguide of a loop-shaped provided on the substrate and forming an optical ring resonator; a first optical gain section having a first electrode provided across a portion of the optical waveguide; and a second optical gain section having a second electrode provided across a portion of the optical waveguide separately from the first optical gain section, the first and second optical gain sections forming a laser oscillator along with the optical ring resonator, wherein the first and second optical gain sections are activated to enable the laser oscillator to oscillate by a forward bias current or by a forward bias voltage, and a laser oscillation state of the laser oscillator is changed by changing an activation level of one of the first and second optical gain sections to change an optical path gain of the optical ring resonator, a change in the laser oscillation state being detected by the other of the first and second optical gain sections.
