摘要： Provided are a speckle-based authentication apparatus, an authentication system that includes the speckle-based authentication apparatus, and an authentication method using the speckle-based authentication apparatus. The speckle-based authentication apparatus includes an optical source configured to radiate light onto an object that is placed apart from the optical source; and a detector configured to detect a speckle pattern generated from the object in response to the light being radiated onto the object and detect location information of the object. Thus, the object is authenticated by comparing the speckle pattern detected by the detector with a speckle pattern stored in advance.

摘要： A multi-wavelength surface plasmon laser that simultaneously emits surface plasmons having a large number of wavelengths and includes an active layer whose thickness changes with position, and a metal cavity whose length changes with position so that light of different wavelengths is emitted according to position. Surface plasmons are generated at the interface between a metal layer and a semiconductor layer in response to the light of different wavelengths. The surface plasmons having different wavelengths may be resonated in the metal cavity whose length changes with position and may be emitted to the outside.
