| Popis: | In order to obtain an integrated structure achieving controllable circular polarization and laser output at 1310 nm, the gain and loss microcavities, magnetic microcavity, and metal layers are used to form a compound structure system, and the 4 × 4 transfer matrix is used to study transmission characteristics of the structure. The strong Faraday rotation effect and gain transmission modes are found through external pump energy, which leads to a circular polarization laser output. The output of circular polarization laser can be controlled by the modulation of external magnetic field. The structure can be functioned as a magnetic switch of circular polarization lasing. |
