Abstract

PURPOSE:To easily connect with other optical circuit having a polarization characteristic, by constituting an optical system by use of a single mode optical fiber to which torsion has been added. CONSTITUTION:A light beam from an interferable light source 9 is made to branch by an optical branching filter 10, one of them is made incident to a single mode optical line 12 for a signal light beam by a lens 11, its emitting signal light beam is irradiated to an object to be recorded 14 by a lens 13, in which it is reflected as a recording light beam to a recording medium 15. On the other hand, the other light beam from the optical branching filter 10 is made incident to a single mode optical line 12' for a reference light beam by a lens 11', and its emitting reference light beam is sent out to the recording medium 15 by a lens 13'. By the recording light beam and the reference light beam which have reached the recording medium 15, an interference fringe is generated, and its interference fringe is recorded in the recording medium 15. To the single mode optical lines 12, 12', torsion exceeding the minimum torsion rate phit0 is provided.
