| 英文摘要 | PURPOSE:To obtain a superior isolator for practically useful laser light causing hardly interposition loss by using a specified Te alloy having the Faraday effect. CONSTITUTION:An isolator is made of an MnTe-HgTe-CdTe alloy as a magnetic semiconductor having the Faraday effect. It is preferable that the alloy has a composition in the range defined by six points, Mn0.1Hg0.2Cd0.7Te, Mn0.1Hg0.4 Cd0.5Te, Mn0.3Hg0.4Cd0.3Te, Mn0.4Hg0.2Cd0.4Te, Mn0.4Hg0.1Cd0.5Te and Mn0.3Hg0.1 Cd0.7Te in the MnTe-HgTe-CdTe ternary phase diagram. The magnetic semicon ductor is preferably formed by epitaxial growth on a substrate of a compound semiconductor consisting of group III and V elements such as an InP or GaAs crystal. Semiconductor laser and an optical isolator can be united to one body, and the reliability as optical parts can be increased. A superior isolator for practically useful laser light of 0.8-5mum wavelength is obtd. |
