QUANTUM WELL INTERSUBBAND TRANSITION DEVICE

摘要

PROBLEM TO BE SOLVED: To achieve a mutual operation with TE mode light in addition to a mutual operation with light of a conventional TM mode; and to achieve high efficiency and high performance of devices since quantum well intersubband transition is applied to an infrared image sensor, a quantum cascade laser, and an ultra high-speed light modulation element.;SOLUTION: A method for generating intersubband electron transition by TE mode light (electromagnetic wave) is invented by using a semiconductor having anisotropy in effective mass of electrons and forming a quantum well structure in a direction inclined from a main axis in an equal energy face.;COPYRIGHT: (C)2008,JPO&INPIT
