Title: Fiber type optical isolator
Inventor: SATO YASUSHI
IPC: G02B6/02
Filed: 1993-12-27
Abstract: PURPOSE:To provide the fiber type optical isolator which consists of a small number of components, and is reducible in size, wide in application, and large in utilization value. CONSTITUTION:The fiber type optical isolator is constituted by removing part of the clad 3 of a single-mode optical fiber 1 installed while bent having curvature and loading the removal part with a magnetooptic material 4, and then a magnetic field is applied at right angles to the propagation direction of light to cause a nonreciprocal phase shift by magnetooptic effect in the core 2 of the single-mode optical fiber 1; and the relation of loss due to the bending of the optical fiber 1 with the value of a propagation constant is utilized to vary an attenuation quantity in the opposite direction from the forward direction. Consequently, a lens is not necessary and there is no polarizer, etc., so the need for optical alignment is eliminated to decrease the number of components; and the optical fiber itself is used as an optical isolator to reduce the size, and there is no incidence/projection surface present halfway, so reflected light from the inside of the optical isolator is reduced. Further, the isolator can be added directly to an optical fiber for transmission, so the fiber type optical isolator which is wide in application and large in utilization value is obtained.
