Abstract:
An optical signal transmission system comprising:a light source emitting an optical beam; a high-frequency signal generator producing a high-frequency signal; a magneto-optical modulator modulating the optical beam emitted from said light source, said magneto-optical modulator including a polarizer, a magneto-optical element, an analyzer, a dc field generator, a high-frequency field generator, and an impedance adjuster, the dc field generator working to apply a dc bias field to the magneto-optical element, the high-frequency generator being responsive to the high-frequency signal from said high-frequency signal generator to apply a high-frequency field to the magneto-optical element, the impedance adjuster working to adjust impedance of the high-frequency field generator; an optical fiber transmitting the optical beam modulated by said magneto-optical modulator; and an optical receiver receiving the modulated optical beam transmitted through said optical fiber.
