ABSTRACT:
A laser-induced optical wiring apparatus is provided wherein optical wiring is realized by digital operations of a laser oscillator. The apparatus includes optical ring resonator formed of a loop-shaped optical waveguide on substrate. At least two optical gain sections are provided on the optical ring resonator. When each optical gain section is activated, a laser oscillator including the optical ring resonator and optical gain sections is enabled to oscillate. In this state, the gain of at least one of the optical gain sections is changed in accordance with an input signal, thereby changing the optical route gain of the optical ring resonator to change the oscillation state of the laser oscillator. A change in the laser oscillation state is detected by the optical gain section other than the at least one optical gain section, whereby an output signal is acquired.
