Title:
光線指向光学構造体
Document Type and Number:
Japanese Patent JP3529387
Kind Code:
B2
Abstract:
An apparatus for directing light in a desired direction comprises a first waveguide, a second waveguide and a multiplicity of prisms. The first waveguide has a first edge and a second edge opposed thereto, and an index of refraction higher than that of its surroundings. The second waveguide is quadrilateral and has an index of refraction higher than that of its surroundings. The second waveguide has third, and fourth edges; the first edge of optically coupled with and sized to fit the first edge of the first waveguide; the fourth edge opposed to the first edge of the second waveguide; said fourth edge defining an input face; the second and third edges connecting said first and fourth edges and each defining respective acute angles with said first edge. The prims are optically coupled with a face of said planar first waveguide.
