摘要： An optical phase conjugator includes an optical nonlinear medium for receiving original signal light and pumping light, and generating and outputting phase-conjugate light by a nonlinear optical effect. The optical nonlinear medium contains an element which can be activated upon irradiation of activation light and has an amplification function with respect to at least the pumping light. The optical phase conjugator comprises a first optical coupler for coupling the original signal light and the pumping light and then inputting the coupled light into the medium, and a second optical coupler for inputting the activation light into the medium. An improvement in phase-conjugate light generating efficiency is attained, and phase-conjugate light having a sufficiently high intensity can be obtained by the optical phase conjugator with a simple, compact arrangement.

摘要： An optical isolator not dependent on the plane of polarization of an incident beam and does not allow the plane of polarization to change on the outgoing side. The optical isolator comprises a first parallel flat double refractive crystal substance; a first Faraday rotor for rotating the plane of polarization of a beam; a second parallel flat double refractive crystal substance; a second Faraday rotor for rotating the plane of polarization in a direction opposite to that in which said first Faraday rotor rotates the plane of polarization; a third parallel flat double refractive substance; a fourth parallel flat double refractive substance; and permanent magnets for magnetizing the Faraday rotor and second Faraday rotors. Since a pair of Faraday rotors for rotating the plane of polarization in opposite directions, the plane of polarization on the incident side does not change on the outgoing side.

摘要： A method for optical switching using an optical directional coupler. In a first step, excitation light is supplied to an interaction region of the coupler having input and output ports. The interaction region is doped with an active ion having the capability for optical amplification. In a second step, signal light is inputted to one of the input ports and amplified in the interaction region. In a third step, the signal light is outputted from one of the output ports depending on whether saturation of optical gain takes place or not.
