Title: Laser integration light modulator
Inventor: SATO KEIJI
IPC: H01S5/00
Filed: 1989-04-12
Abstract: PURPOSE:To decrease light noises by arranging an absorbing layer, which has a band gap equal to an active layer or narrower than that, in parallel with a variable light absorbing layer, within at least either of the upper side clad layer and the lower side clad layer of a light modulator. CONSTITUTION:When laser beams enters a light modulator 19 from the active layer 11 of a semiconductor laser 17, if they are subjected to the scattering at the optical interface between them, they advance to the clad layers 3 and 5 on the outsides without being introduced into a variable light absorbing layer 1. Since the clad layers 3 and 5 are transparent for the laser beams, the scattered light advance as it is. But, since absorbing layers 7 and 9 are provided at the destinations of the scattered lights, the laser beams which reached these absorbing layers 7 and 9 are absorbed, and are not emitted to the outside, so the S/N of the signal light viewed from the emitting face improves. By providing the absorbing layers 7 and 9 at least at either of the upper side clad layer 3 and the lower side clad layer 5 of the light modulator 19 this way, it can absorb the scattered lights and reduce the noises of a laser integration light modulator.

Title: Wavelength variable pseudo phase matching element
Inventor: NAGANUMA KAZUNORI
IPC: G02F1/37
Filed: 1998-04-06
Abstract: PROBLEM TO BE SOLVED: To provide a wavelength variable pseudo phase matching element whose phase matching wavelength can be changed/adjusted by means of a rotation mechanism, which can directly be substituted with a conventional angle phase matching element and whose manufacture is easy. SOLUTION: Polarization is given into a non-linear optical medium board in the direction of a period wave number in terms of an equal period. The rotation center 109 of the non-linear optical medium board 101 is paced on the extension line of an optical path before converted light reaches an incident end face 104. The intra-board optical axis 106 of conversion light and the period wavelength direction of polarization make an angle which is to zero. In the wavelength variable pseudo phase matching element, phase matching wavelength can be changed/adjusted not by a parallel shift mechanism but by a rotation mechanism. Thus, the wavelength variable pseudo matching element cant be substituted for the non-linear medium of a present correlation meter and measurement sensitivity can considerably easily be improved.

Filed: 1990-04-09
Abstract: PURPOSE:To maintain excellent resolution by providing a guide path leading a lighting light to an original face between a glass base and a transparent protection and leading a reflected light to a photoelectric conversion element to each photoelectric conversion element. CONSTITUTION:A light radiating from a light source 14 radiates an original face 19 through a light guide window 13 and a core part 20 with each picture element, the reflected light is led to a photoelectric conversion element 11, from which electric picture information is obtained. In this case, since the light radiating to the face of the original 19 passes through the core part 20 of the guide path, the diffusion to adjacent picture elements is reduced. Moreover, the quantity of incident stray light made incident with a larger angle than the aperture angle of the guide path in the reflected light from the face of the original 19 is reduced by a scatterer in a clad layer 21. As a result, crosstalk to an adjacent photoelectric conversion element 11 is reduced and the resolution of the image sensor is improved.
