The optical isolator's magneto-optical layer (16) may be a layer of ferromagnetic metallic material, such as a Fe-Co metallic alloy, or a magnetic oxide layer An optical device comprises at least one integrated optical structure.

An optical integrated unit and an optical pickup device capable of easily preventing such troubles as erroneous detections.

The embedded optical fiber has a core and a cladding surrounding the core.

  The invention further relates to an integrated lens which comprises one such waveguide device and to a manufacturing method for a corresponding, optical component.

A component and the like in the optical integrated unit (15) can be flexibly arranged.

The MIOC also has an encrypted message output.

A high density integrated optical chip (20).

An optical device comprises an optical diffuser structure embedded between media of substantially the same optical refractive index.

An integrated optical microstructure includes a substrate (245) carrying an optical waveguide (240) and supporting a medium (210) disposed to receive optical energy from the waveguide.

The inventive optical waveguide is especially suitable for use as an integrated optical waveguide for the transfer of information in optical telecommunications.

In some embodiments, an integrated optical polarization combining prism is used.

The MIOC comprises two divergent paths with mirrored ends.

Devices and techniques for integrated optical data communication.

An interconnection platform (8) used for interconnecting an embedded optical-fiber (9) and an interconnecting optical-fiber (7) is formed at the notch.

  Then, by further moving the base (11) toward the optical connector (73), a core wire (91) provided in the optical fiber (90) can be connected to the built-in optical fiber.
