Integrated magneto-optical modulator with optical isolator, method of manufacturing the same and optical communication system using the same |
摘要 |
The integrated magneto-optical modulator with optical isolator of the present invention comprises an optical isolator unit, a magneto-optical modulator unit, an impedance adjuster. The optical isolator unit rotates a polarization of an incident light from a light source to transmit the light with rotated polarization, and eliminates a reflected feedback light toward the light source. The magneto-optical modulator unit modulates an intensity of the light from the optical isolator unit and transmitting the modulated light outside. The impedance adjuster adjusts electrical impedance at the magneto-optical modulator unit in order to effectively introduce the high-frequency signal for light modulation to the magneto-optical modulator unit. Further, the optical isolator unit and the magneto-optical modulator unit are contained a single package.
