Title: Production of optical fiber coupler
Inventor: FUKUMA MASUMI
IPC: G02B6/28
Filed: 1990-01-17
Abstract: PURPOSE:To allow the execution of exact control by correcting an inclination angle to exactly measure a welding quantity and detecting the edge of the outside diameters of optical fibers, thereby enhancing the measurement accuracy of the outside diameters. CONSTITUTION:The outside diameters d of two pieces of the optical fibers which are disposed in contact with each other are measured and COStheta is calculated in accordance with the relation COStheta=d/(d1+d2) from these values. The welding quantity W to be important at the time of welding is calculated by following equation: W=(d-d')COStheta, where d' is the outside diameter of the optical fibers at the time of the welding. The welding is stopped and the fibers are stretched by applying a specified tension thereon when the prescribed W is attained. The stretching is stopped at the point of the time when the prescribed branching ratio is obtd. while the branching state is measured by a light source and power meter connected previously to the optical fibers in the stretching stage. The branching ratio of the broad wavelength branch coupler is efficiently controlled in this way and the yield is improved.

Filed: 1990-01-17
Abstract: PURPOSE:To allow scanning in a correctly multiplexed state even if plural light beams line up in the direction corresponding to sub-scanning by adjusting the disposition of a light source unit so as to minimize the fluctuation of a light spot in the sub-scanning direction by the plural light beams reflected from the respective reflecting surfaces of a rotary polyhedral mirror. CONSTITUTION:The light quantity in the direction corresponding to the sub- scanning direction on a body to be irradiated by the entire part of the plural light beams 14 emitted from the light source unit is monitored. The disposition of the light source unit 13 or the multiplexing optical system is so adjusted as to minimize the fluctuation of the light spot in the sub-scanning direction on the body to be irradiated by these plural light beams 14. The deviation in the position of the light spot by the influence of the rotary polyhedral mirror 15 is obviated in this way even if the plural light beams 14 line up in the direction corresponding to the sub-scanning direction.
