Title: Optical components and optical isolator and optical circulator using same
Inventor: SANUKI MINORU
IPC: G02B27/28
Filed: 1995-03-03
Abstract: PURPOSE: To reduce the difference between Faraday rotational angles by suppressing the influence of variation of Faraday rotational capacity at the place of a magnetic optical element while making two separated lights passed through an unsaturation type magnetic optical element and double refraction elements pass the same place of the magnetic optical element. CONSTITUTION: An optical isolator is constituted of a double refraction plate 10, a refractive index distribution type lens 11, a Faraday rotator 13, a halfwave length plate 14, a refractive index distribution type lens 11 and a double refraction plate 16. When an incident light of a forward direction and a backward direction is passed through the Faraday rotator by being separated into a normal light and an abnormal light, lenses 11, 15 are constituted so that light axes of separated lights are intersected with each other in the rotator.  When this isolator is compared with an isolator made by having the same constitution and the same dimensions as those of this isolator and without having refractive index distribution type lenses making the incident light converge on the Faraday rotator, this isolator is superior to the isolator made newly by 2.8nm which is the difference between peak wavelengths of isolations.

Abstract: PROBLEM TO BE SOLVED: To output a normal FG pulse to a drive circuit when a delay circuit inputs an induced voltage of each phase and delays the phase where the same phase leading is generated in every one period of these induced voltages to compensate for phase leading to output the compensated induced voltage. SOLUTION: An induced voltage generating circuit 3 inputs the voltage of each phase of a multi-phase motor 2 to output induced voltages 6u, 6v, 6w of each phase. The phase where the same phase leading is generated is delayed in every period by the delay circuits 8u, 8v, 8w to compensate for the phase leading to output the compensated induced voltages 9u, 9v, 9w. The FG pulse generating circuit 4 inputs the compensated induced voltages 9u, 9v, 9w to output the FG pulse. Thereby, pulse interval becomes equal and unevenness of rotation can be reduced.
