Abstract: The present invention provides a measuring apparatus for biological information which permits accurate determination for biological information without causing the subject much discomfort. The measuring apparatus for biological information of the present invention uses an ear receiver-shaped sensor element which is placed and held on the perimeter of the subject's external auditory meatus opening with the light emitter and the light receiver brought into contact with the subject. The light receiver detects the light projected to and passed through the subject. The apparatus is also provided with a signal processor which performs calculation for biological information of the subject on the basis of the intensity of light detected by the light receiver.

Abstract: When a laser beam enters into a grating coupler at a right angle, a guided wave with a wave mode corresponding to an incident angle can be generated. Although the guided wave is a light beam in single mode, the waveguide mode is deflected by passing through a step-wise structure and is converted into several guided waves having several modes. When the guided waves are radiated from a straight output grating coupler, the radiant angle is dependent upon the waveguide mode, so beams are radiated in different directions according to their respective waveguide modes. Therefore, a guided wave in zero-order mode outputs a radiant beam having a larger radiant angle, while a guided wave in first-order mode outputs a radiant beam having a smaller radiant angle.
