Title:
熱輻射光源
Document Type and Number:
Japanese Patent JP6795853
Kind Code:
B2
Abstract:
A thermal radiation light source 10 includes a laminated body (10S) including m quantum well structure layers (111, 112) laminated where m is an integer of 2 or more, and including an n-layer (121, 122) and a p-layer (13) sandwiching each of the quantum well structure layers from both sides in the laminating direction wherein the n-layer is made of an n-type semiconductor and the p-layer is made of a p-type semiconductor; a voltage applying unit (151, 152) that is provided for each of the m quantum well structure layers and is directly or indirectly connected to the n-layer and the p-layer sandwiching each quantum well structure layer and that applies a voltage for moving to the n-layers or the p-layer a charge in a quantum well of each quantum well structure layer; a voltage switching unit (161, 162, 17) that switches ON/OFF of application of the voltage to each of the m quantum well structure layers; and a photonic crystal portion (20) disposed in the laminated body or adjacent to the laminated body, and formed so that lights of m kinds of wavelengths resonate, each of the lights of the m wavelengths being generated in each of the m quantum well structure layers corresponding to transition energy between subbands in the quantum well of the quantum well structure layer. The thermal radiation light source 10 can generate a plurality of wavelengths by switching the plurality of wavelengths one by one at a high speed.
