Title: Dynamic pressure air bearing type polygon scanner
Inventor: ITAMI YUKIO
IPC: G02B26/10
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To rotate a polygon mirror in a stable state. SOLUTION: A thrust dynamic pressure air bearing 29 which supports a rotor 15 having a polygon mirror 18 is formed between one end face of the rotor 15 and the inside face of a housing 1. The rotor 15 is provided with an attachment race 23 to which true polygon mirror 18 is attached with a face orthogonal to the axis of the rotor 15. A support member 5 which forms a radial dynamic pressure air bearing 27 between itself and the peripheral surface of the rotor 15 is supported through an elastic member 6 by the housing 1.  Thus, though the gap of the thrust dynamic pressure air bearing 29 is changed by the air pressure when the rotor 15 is rotated, inclination in the axial direction of the support member 5 can be corrected by the bending action of the elastic member 6 even if the perpendicularly of the support member 5 to the inside face or the housing has an error on production, and one end face of the rotor 15 and the inside face of the housing 1 between which the thrust dynamic pressure air bearing 29 is formed are kept parallel to stabilize rotation of the rotor 15.

Abstract: PURPOSE:To monitor an output light level of a semiconductor laser, by dividing a semiconductor laser formed on a semiinsulating substrate into two sections by means of an insulation region intersecting orthogonally the length of a resonator and utilizing one section as a semiconductor laser and the other as a photodiode. CONSTITUTION:A photodiode 11 and a semiconductor laser 12 are formed on a semi-insulating substrate 2 and are seperated from each other by an insulation region 10 intersecting orthogonally the length of a resonator. When electric current is supplied to the laser 12 through an electrode 1, laser oscillation occurs in a stripe within an intrinsic active layer 5 over which there is no block layer 7. Laser beams created in the stripe and directed toward the cleaved resonator end face (rear face) 13 pass through the insulation region 10 and enter into the photodiode 11. The region 10 is formed by implantation of protons and then annealed properly so that laser beams can be propagated in the stripe without loss. In this manner, a level of output light of the laser 12 can be monitored by means of the photodiode 11.

Filed: 1990-05-28
Abstract: PURPOSE:To reduce the size and loss of the title switch and to realize high-speed connection and switching by using optical switches which are combined in a relatively movable state between a pair of end-face plates and provided with optical-path plates having plural optical paths. CONSTITUTION:Optical switches 25-28 are respectively provided with end-face plate pairs 25a and 25b to 28a and 28b and optical-path plates 25c-28c. For example, the switch 25 is positioned at the intersection of optical fiber bundles 21 and 23 and the plate 25c has an optical path (a) which connects two facing end sections to each other in an intersection way, optical path (b) which linearly connects facing two end faces to each other, and optical path (c) which connects two end sections held on the same end-face plate to each other. Accordingly, each optical fiber bundle 21-24 in the line and row directions can be connected to other arbitrary optical fiber bundles 21-24 by moving the end-face plate pair of optical-path plates of each switch 25-28 only. Therefore, this optical matrix switch can make high-speed switching and, at the same time, the loss and size of the switch can be reduced.
