摘要： In an optical amplifier using a rare earth element-doped optical fiber such as an erbium-doped optical fiber, a variation of amplification gain resulting from temperature change is suppressed and the gain-temperature characteristic is enhanced. Moreover, the quantity of temperature compensation in the gain is easily adjustable. Light from an excitation light source is input to an optical fiber for optical amplification comprising a rare earth element-doped optical fiber, via a temperature compensation optical fiber comprising a rare earth element-doped optical fiber such as an erbium-doped optical fiber. By changing the length of this temperature compensation optical fiber, the quantity of temperature compensation is finely adjusted.

摘要： A magnetic device comprises a magnetic element, a first magnetic field applying means, and a second magnetic field applying means. The first and second magnetic field applying means are disposed on mutually opposite sides of the magnetic element. The magnetic element is, for example, an element in which a soft magnetic film is formed in a meandering shape on a nonmagnetic substrate. The first and second magnetic field applying means create a magnetic field in one direction from the first magnetic field applying means toward the second magnetic field applying means. The bias magnetic field in one direction is thereby applied to the entire soft magnetic film in the magnetic element disposed between the first and second magnetic field applying means.
