摘要： A light measuring device is designed, so that excitation light, emitted by a light source, is guided through an excitation light optical fiber to irradiate a sample, and that fluorescence discharged by the sample is guided to an optical detection system through a receiving light optical fiber. A coupling lens is arranged ahead of the excitation light optical fiber and ahead of the receiving light optical fiber on the sample side. A sample container for retaining a sample is so designed that a lens portion, for collecting excitation light and fluorescence, is integrally formed with the cylindrical bottom. According to this arrangement, excitation light is changed to parallel light or converged light by the coupling lens, and is collected at the sample by the lens portion integrally formed with the bottom of the sample container.

摘要： A light-receiving element may easily detect the barycenter of a light intensity of light having a long-wavelength band in an optical communication. An InGaAs layer (i-type layer) and a p-type InP layer are stacked on an n-type InP substrate. Electrodes are formed on both sides of the top surface of the p-type layer, and an electrode is formed on the bottom surface of the n-type substrate. An incident light impinged upon the light-receiving element is photoelectricly-converged into a photocurrent, and the photocurrent flows in the p-type layer to the electrodes. As a result, a current is derived from each of the electrodes, the magnitude thereof being dependent on the distances from the light impinging position to respective electrodes. The barycenter of a light intensity may be calculated from the currents derived from the electrodes and a light intensity may be obtained from the summation of the currents.

摘要： An optical module according to the invention includes an optical fiber, a planar lens, and a flat plate-like transparent member for optically coupling the optical fiber and the planar lens to each other. The transparent member has a nearly spherical concave portion formed in a surface of the transparent member. An end surface of the optical fiber is inserted into the concave portion of the transparent member so as to abut thereon and bonded and fixed thereinto. Further, a surface of the transparent member opposite to the surface in which the concave portion is formed is joined to a surface of the planar lens to make an optical axis of the optical fiber coincident with an optical axis of the planar lens. The concave portion is filled with a filler material having a refractive index higher than that of the transparent member to thereby fix the optical fiber.

摘要： An optical demultiplexer has an optical fiber, a single collimator lens, a diffraction grating, and an array of photodetectors. A light beam emitted from the optical fiber is demultiplexed by the collimator lens and the diffraction grating into light beams, and the light beams are focused by the collimator lens as beam spots deformed due to an aberration of an optical system of the optical demultiplexer onto the photodetectors. The photodetectors are arranged to accommodate and detect all the deformed focused beam spots. The array of photodetectors comprises a linear array of photodetectors or a matrix of photodetectors.
