| 英文摘要 | PURPOSE:To allow the execution of 100% mode conversion even if th phase matching between modes is not executed by simultaneously applying an electric field and magnetic field to a waveguide to induce the mode conversion by an electro-optical effect and magneto-optical effect within the same region, thereby compensating the degradation in the mode conversion efficiency by phase mismatching. CONSTITUTION:This optical isolator is constituted of a GaAs substrate 31, a buffer layer 32, a lower clad layer 33, a core layer 34, an upper clad layer 35, a mesa structure 36, and electrodes 37, 38. The isolator has the waveguide consisting of a magnetic semiconductor, such as CdMnTe, and induces the mode conversion between the orthogonal modes of TE light, TM light, etc., by the electro-optical effect and magneto-optical effect within the same region by simultaneously impressing the electric field E and the magnetic field H to the waveguide. The degradation in the mode conversion efficiency by the phase mismatching is compensated. The 100% mode conversion is attained in this way even if the phase matching between the modes is not executed. |
