Latest Patents

Fukuzaki holds a patent for an in-line optical isolator. In conventional optical isolators, optical signals can be dispersed by polarization or affected by heat generation in a garnet crystal. His invention orients the crystal optical axis of rutile crystal so that the separation directions of the ordinary ray (O) and the extraordinary ray (E) are perpendicular to the plane that includes the optical axes of optical fibers. Additionally, the focusing central optical axis of a focusing rod lens is arranged parallel to the optical axes of the optical fibers and at a substantially equal distance from the ordinary and extraordinary rays propagating along the optical axis of the optical fiber. An air gap of about 200 micrometers is provided as a heat insulating means between the focusing rod lens and a magnetized garnet crystal.
