MAGNETICALLY POLARIZED PHOTONIC DEVICE

摘要

A magnetically polarized photonic device is provided. The magnetically polarized photonic device (100) includes substrate (102), an annihilation layer (106) and a graded band gap layer (142). The annihilation layer (106) is deposed on a surface (104) of substrate (102) with graded band gap layer (142) disposed on annihilation layer (106). Contacts (116, 128) are disposed on ends (146, 150) of magnetically polarized photonic device (100). A magnetic field (159) is applied to graded band gap layer (142) and annihilation layer (106) to drive charges to contacts (116, 128).
