Abstract: Provided is a quantum dot (QD) light modulator and an apparatus including the QD light modulator. The QD light modulator may include a QD-containing layer including QDs having light-emission characteristics, a refractive index change layer arranged adjacent to the QD-containing layer, and a reflector arranged facing the QD-containing layer. The refractive index change layer may include a carrier density change area in which a carrier density changes, and the carrier density change area may be arranged adjacent to the QD-containing layer. The light-emission characteristics of the QD-containing layer may be modulated according to a change in a property of the refractive index change layer. The QD light modulator may further include a nano-antenna structure arranged on the QD-containing layer.

Abstract: A polarimeter for measuring a polarization rotation caused by a measurement object is provided, the polarimeter including an optically active material. The polarimeter includes a light source unit for irradiating a measurement object with light having a specific polarization; an anisotropic meta surface element for splitting reaction light, obtained by reacting the light of the specific polarization irradiated by the light source unit with the measurement object, into first and second reaction light; and a detection unit for detecting the first and second reaction light separated by the anisotropic meta surface element according to polarization. The polarization rotation caused by the measurement object may be calculated by comparing detection signals of the first and second reaction light detected by the detection unit.
