  • Optical distance sensor
    Patent number: 6972834
    Abstract: An optical distance sensor includes a first substrate provided with a light emitting element and a light detecting element, a one-piece optical structure body on a second substrate, the optical structure body having optical elements for converging incident light in a direction parallel to a surface of the second substrate and for converging an outgoing light beam from the light emitting element and a light beam reflected by an object in the direction parallel to the surface of the second substrate, and lenses for converging incident light in a direction perpendicular to the surface of the second substrate and for converging the outgoing light beam from the light emitting element and the light beam reflected by the object in the direction perpendicular to the surface of the second substrate, respectively.

  • Sensor head
    Publication number: 20030007752
    Abstract: A sensor head includes a first substrate provided with a light emitting element and a light receiving element, an optical structure body formed in one piece on a second substrate, the optical structure body having a plurality of optical elements intended for converging incident light in a parallel direction to a surface of the second substrate, for converging an outgoing beam from the light emitting element and a light beam reflected by an object to be measured in the parallel direction to the surface of the second substrate, and lenses intended for converging incident light in a perpendicular direction to the surface of the second substrate, for converging the outgoing beam from the light emitting element and the light beam reflected by the object to be measured in the perpendicular direction to the surface of the second substrate, respectively.

  • Method of making an integrated optical component and an integrated optical star coupler made in accordance with said method
    Patent number: 6067388
    Abstract: The invention is directed to a method for making integrated optical components having strip waveguides (11 to 15; 21 to 2M) and a layer waveguide 53. A mask 4 having a lattice structure 3i functions to generate the layer waveguide 53 via ion exchange. The method of the invention is suitable for making couplers having free spaces with low attenuation and is especially suitable for arrayed waveguide grating multiplexers. The invention also is directed to an integrated optical component made pursuant to the method of the invention.
