| titleOfInvention | Quantum optical transmission device and quantum optical generator device therefor |
| abstract | A squeezed light generating method using the Kerr effect of an optical fiber is relatively easy, but the requirements in manufacture such that a beam must be divided accurately at 50:50 are large. In addition, it is desirable that the squeezed light can be generated with arbitrary wavelength and pulse width from the viewpoint of the communication application. For that reason, the squeezed light generator of this invetion is made up of an arbitrary optical fiber, a means for temporally separating two linearly polarized components, two Faraday rotators and a high-reflection mirror. Pulse lights that are temporally separated into two orthogonally polarized components at an intensity ratio of 50:50 are reciprocatively propagated in the optical fiber, and the polarized light is rotated by 90° in an outward transmission. Since those two polarized components pass through the optical paths which are accurately equal to each other in the outward and homeward transmissions, those two polarized components interfere with each other accurately at 50:50 after reciprocation through the fiber. The interfered beam is separated by a polarizing beam splitter that is high in an extinction ratio. When the polarized lights before inputting the fiber and after reciprocating coincide with each other, it is unnecessary to maintain the polarization in the fiber propagation, and an arbitrary fiber can be used. |
