摘要： 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.

摘要： Provided are photoelectric devices and electronic apparatuses including the photoelectric devices. A photoelectric device may include a photoactive layer, the photoactive layer may include a nanostructure layer configured to generate a charge in response to light and a semiconductor layer adjacent to the nanostructure layer. The nanostructure layer may include one or more quantum dots. The semiconductor layer may include an oxide semiconductor. The photoelectric device may include a first electrode and a second electrode that contact different regions of the photoactive layer. A number of the photoelectric conversion elements may be arranged in a horizontal direction or may be stacked in a vertical direction. The photoelectric conversion elements may absorb and thereby detect light in different wavelength bands without the use of color filters.
