Title: Optical modulator
Inventor: SUGIYAMA MASAKI
IPC: G02F1/035
Filed: 2009-02-10
Abstract: <P>PROBLEM TO BE SOLVED: To provide a compact and inexpensive optical modulator having a plurality of optical modulation units arranged in parallel on a substrate including a polarization inversion region, and applying input light rays to the optical modulation units with a low loss.  <P>SOLUTION: In the optical modulator, each of light beams obtained by branching one input light are input to optical modulation units 20A and 20B arranged in parallel on the same substrate 10 including the polarization inversion region Pi via curved waveguides 13A and 13B. In MZ type optical waveguides of the optical modulation units 20A and 20B, a spacing between the pair of branching waveguides of the adjacent optical modulation units is formed so as to be wider in the vicinity of a border of an input side polarization inversion region than in the vicinity of a start point of an interaction portion INT. As a result, even if signal electrodes 31A and 31B of the optical modulation units shift at the boundary portion of the polarization inversion region, the spacing between the signal electrodes does not become narrow, and hence the radius of curvature of each of the curved waveguides 13A and 13B for guiding the input light to each of the optical modulation units can be increased.  <P>COPYRIGHT: (C)2010,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To increase a recognition rate of an object such as a pedestrian by preventing image deterioration caused by an influence of a high-brightness light source such as a headlight of an oncoming car or direct sunlight.  <P>SOLUTION: A multi-slit method is adopted, wherein a passing body of a light wavelength selective band passing system is installed in front of a camera, and image deterioration is prevented, and the recognition rate of the object such as a pedestrian is increased, and the position of the object is calculated from a vanishing point of a captured image.
