Optical nonlinear evaluation device and optical switching element |
摘要 |
An optical nonlinear evaluation device (1) capable of accurately evaluating the optical nonlinearity of a Kerr medium in accordance with a phase difference caused by cross-phase modulation generated in the Kerr medium includes: a polarization Sagnac interference path (3) provided with a Kerr medium (4); an optical pulse light source (7) for supplying a signal beam (Dsig); a polarization beam splitter (PBS1) for splitting the signal beam (Dsig) into a signal beam (Hsig) and a signal beam (Vsig) polarized in a direction orthogonal to the signal beam (Hsig), for supplying the signal beam (Hsig) to a first side of the Kerr medium (4), and for supplying the signal beam (Vsig) to a second side of the Kerr medium (4); a glass plate (14) for entering, onto the signal beam (Hsig), a control beam (Vcont) for causing a change in phase difference between the signal beam (Hsig) and the signal beam (Vsig); separating means for separating the control beam (Vcont) from the signal beam (Hsig) having traveled through the Kerr medium (4); and a detection section (10) provided so as to detect the phase difference between the signal beam (Hsig) and the signal beam (Vsig).
