Patent JP-H0274932-A (JP)
Title: Optical receiver
Inventor: WATABE KIMITAKA
IPC: H04B10/255
Filed: 1988-09-12
Abstract: PURPOSE:To copy photon number information of a signal optical pulse to phase information of a probe optical pulse and to suppress the influence by quantum noise so that said information can be read out in a high S/N by using an output optical pulse of a degeneracy parametric amplifier as the probe optical pulse and allowing it to collide with the signal optical pulse. CONSTITUTION:Optical pulses 1-3 are made incident on an optical fiber in which there is a negative dispersion. Subsequently, the number of photons and a half- amplitude level of the optical pulses 1-3 are determined in advance so as to form an optical soliton, and by a wavelength dispersion, the signal optical pulse 3 is emitted from the optical fiber 5 in order of an emitted reference optical pulse 6, an emitted probe optical pulse 7 and an emitted signal optical pulse 8. By an optical switch 13, a reference optical pulse 14 and a probe optical pulse 15 are separated and a delay is supplied to the probe optical pulse 15 side, and by its delay, the probe optical pulse 15 and the reference optical pulse 14 interfere with each other by 50-50% on a half mirror 16. A differential synthesizing circuit 19 fetches a phase difference of the probe optical pulse 15 and the reference optical pulse 14 as a differential output. In such a way, photon number information of the signal optical pulse is copied to phase information of a probe light, and also, since a GAWBS noise is suppressed, an S/N is improved.

Title: Faraday rotor
Inventor: SHIRASAKI MASATAKA
IPC: G02F1/09
Filed: 1982-12-28
Abstract: PURPOSE:To obviate the generation of abnormal fluctuation in light level in the stage of changing over a Faraday rotational angle by providing means for impressing the magnetic field which inverts the magnetization in a rotor while maintaining said magnetization in a satd. state in the stage of changing over the magnetic field. CONSTITUTION:A magnetic field in a certain direction in a light transmission direction is preliminarily impressed by a means for changing a rotational angle on a Farady rotor 1 consisting of a thin YIG plate, a means for impressing a magnetic field for changing the Faraday rotating angle, and a means 3 for impressing a magnetic field for maintaining a satd. state. A magnetic field necessary for maintaining the magnetization in the rotor 1 in a satd. state is impressed on said rotor in order to induce the effect of Faraday rotation in an opposite side. If the magnetic field in the opposite direction is thereafter impressed on the rotor by the means for changing the rotational angle, the magnetization in the plate 2 is inverted while maintaining the satd. state and there is no possibility of generating an abnormal fluctuation in the light level in the mid-way of inversion. The irregular fluctuation in the magnetic domain in the element is thus prevented in the stage of changing over the effect of the Faraday rotation and the abnormal fluctuation in the light level is eliminated.
