Abstract: Systems and techniques of incorporating an optical resonator in an optical part of a feedback loop in opto-electronic oscillators. This optical resonator provides a sufficiently long energy storage time and hence to produce an oscillation of a narrow linewidth and low phase noise. Certain mode matching conditions are required. For example, the mode spacing of the optical resonator is equal to one mode spacing, or a multiplicity of the mode spacing, of an opto-electronic feedback loop that receives a modulated optical signal and to produce an electrical oscillating signal.

Abstract: A system and method for automatically attenuating optical signals transmitted in optical systems. The system and method exploits a wavelength-locked loop servo-control circuit and methodology that enables real time mutual alignment of the center wavelength of an optical signal having a peaked spectrum function and transmitted through the optical system, and a center wavelength of a wavelength selective device such as an optical filter element implementing a peaked passband function. The wavelength-locked loop servo-control circuit and methodology particularly is capable of real-time aligning the center wavelength of an optical signal in a range between maximum overlap with the center wavelength of the peaked passband function of the optical filter for maximum transfer of output optical signal by the filter element and minimum overlap with the peaked passband function of the optical filter so that output optical signal may be attenuated in the optical system.

Abstract: The light sensor has a plate-shaped light guide in which a plurality of reflection portions each comprising a V groove are parallelly arranged on one plane thereof. An end face of the light guide which faces the side surfaces of the V grooves is opposed to a light emitting face of a light emitter. Light receivers are disposed at an appropriate distance from the light guide so that the light receiving faces thereof are opposed to the other plane of the light guide. Light emitted from the light emitter is taken in the light guide, is reflected at the reflection portions, and is ejected from the other plane toward the light receivers. With the light sensor, the range of detection by one light emitter is large, it is easy to adjust the optical axes, and the number of provided light emitters can be reduced.

Abstract: There is provided a liquid-level gauge for accurately measuring a liquid-level height of fluid to be measured. In the liquid-level gauge, a float having a uniform cross-sectional form in the height direction and a specific weight value small than that of liquid is dipped in the liquid. The float is supported by an optical fiber at a constant height such that its upper end always projects from the liquid level. One end of the optical fiber is connected to an optical fiber strain gauge and a strain detector is turned round between fiber support members. When the float receives buoyancy from the liquid, tension is applied to the strain detector of optical fiber to generate strain therein. By detecting the strain by means of an optical fiber strain gauge, a liquid-level height can be measured.

Abstract: An apparatus for sensing strain applied to a region of a hydrocarbon well comprises an optical fiber in communication with the region. The optical fiber is responsive to strain applied to the region and to a light signal transmitted through it, in order to produce a sensing light signal incorporating scattered light. A characteristic of the scattered light is indicative of the strain being applied to the region.

Abstract: An optical tweezer device for capturing minute bodies on a stage in accordance with very fine patterns. A fiber array light source of the device is equipped with a laser module which is structured with a high-luminance, high-power multiplex laser light source. High-intensity laser light which is emitted from this fiber array light source is modulated by a DMD and focused by a microlens array. The focused light enters corresponding optical fiber cores which are arranged in a matrix form at an array head, and is guided in the fibers. The light focused by the microlens array is caused to enter the fiber cores corresponding to the microlenses with high efficiency. The optical fibers are two-dimensionally arrayed to correspond with pixel portions of the DMD. High-intensity laser light is emitted from the array head in accordance with an on-off pattern of the DMD.

The method includes a step of embedding a sensor part of an optical fiber sensor in an adhesive joining a plurality of members together. The sensor part is embedded in the adhesive in such a way that the sensor part undergoes a compressive strain. Separation of the bond is detected on the basis of an optical characteristic of the sensor part when light from a light source is directed into the optical fiber sensor.
