반사와 굴절의 제어를 위한 반도체 pn 접합 구조 및 광 경로 제어 방법

Abstract

According to the optical device for the semiconductor for using the preferred embodiment of the present invention, refraction or the reflex control of light can be reached based on the semiconductor silicon with p n junction structures and waveguiding structure.Also, according to the optical device for using semiconductor of the present invention, by using the amplitude of the control energy directly modulation light of reflection or refraction.Optical device according to the preferred embodiment of the invention, including：First wave guide, incident optical signal, and formed by direction identical with incident optical signal；Second waveguide forms certain angle from the first wave guide；And reflector, the refractive index variable according to the voltage of application, and then the access of optical signal can be selected by the first wave guide or second waveguide, and the inclination angle of certain angle is formed with the first wave guide.
