Abstract:
1. A laser device, comprising: a gain medium having a gain with respect to a specific electromagnetic wave; a resonator structure for resonating the electromagnetic wave; a waveguide formed by interposing the gain medium between a first cladding and a second cladding each including a negative dielectric constant medium whose real part of a dielectric constant thereof is negative with respect to the specific electromagnetic wave; and a resistor element for stabilizing a potential difference between the first cladding and the second cladding, the resistor being provided to a portion where a surface current in the first cladding is maximum with the second cladding being set as a reference when the electromagnetic wave propagates in the waveguide, wherein the resistor element includes a schottky barrier generated between a metal and a semiconductor.
