発明の名称 (英語) THERMAL-RADIATION LIGHT SOURCE AND TWO-DIMENSIONAL PHOTONIC CRYSTAL USED THEREIN
発明の概要(英語) This invention provides a thermal-radiation light source that allows light-intensity changes with a response speed on par with photoelectric conversion elements. Said thermal-radiation light source (10) is provided with a two-dimensional photonic crystal (12) in which an n layer (112) comprising an n-type semiconductor, a quantum-well-structure layer (114) that has a quantum-well structure, and a p layer (111) comprising a p-type semiconductor are stacked in that order to form a plate (11) inside which different-refractive-index regions (holes (121)), each of which has a refractive index that is different from those of the n layer (112), the p layer (111), and the quantum-well-structure layer (114), are laid out in a periodic manner so as to resonate with light of a specific wavelength corresponding to the transition energy between subbands in the quantum wells in the quantum-well-structure layer (114). This thermal-radiation light source (10) is also provided with a p-type electrode (131) and an n-type electrode (132) for applying, to the abovementioned plate (11), a voltage that is negative on the side corresponding to the p layer (111) and positive on the side corresponding to the n layer (112).
