Patent JP-H095688-A (JP)
Title: Optical modulator and optical electric field sensor
Inventor: MURAMATSU RYOJI
IPC: G01R29/12
Filed: 1995-06-20
Abstract: PURPOSE: To make it possible to detect only noise-free signal light by arranging a pair of Faraday elements so as to hold an optical joining point having the high possibility that unnecessary reflected light is generated within an optical transmission path therebetween and separating these elements by varying the plane of polarization with the exit light from an optical modulator or sensor head. CONSTITUTION: The exit light which is linearly polarized light from a light source 7 propagates to an optical circulator 5 and a polarizer 13 via an optical fiber 27. There is no change in the plane of polarization at this stage. The plane of polarization of the light passed through a second Faraday rotator 12 magnetically satd. by a permanent magnet not shown in Fig. is rotated 45 deg.C. The light is thereafter passed through a first Faraday element 11 magnetically satd. via an optical fiber 21, etc., including optical connectors 15, 16 which are the cause for the generation of the return light by reflection and is made incident on an optical modulator 1. The plane of polarization receives 45 deg. rotation in the state that the light passes the first Faraday element 11. The plane of polarization is thus eventually rotated 90 deg. in total.  As a result, the signal light is detected by removing noise even in the state than this noise is generated.
