Laser device, optical circuit system, sensing system, laser light generating unit, and metamaterial

Abstract

An object of the present disclosure is to provide a laser that can oscillate laser light in an infrared region (for example, light in a communication wavelength band) and that has a low laser oscillation threshold value and reduces an optical loss. The present disclosure provides a laser device including a laser light generating unit having a nanostructure configured to exhibit a BIC mode and including a perovskite material, the laser light generating unit being configured to oscillate infrared light. The nanostructure may be configured to exhibit a zero refractive index. For example, the nanostructure may be formed by the perovskite material, or the nanostructure may be formed by a dielectric material, and provided in the perovskite material.

Dependencies are inferred from the claim text.
