Optical package substrate and optical device

An optical device having an optical component and/or optical element mounted on an optical package substrate,

• the optical package substrate comprising:
• a guide section for fixing an optical axis of an optical fiber mounted in the guide section, the guide section being a groove formed on a surface of a substrate and extending from an end face of the substrate to a predetermined portion of the substrate;
• and
• an optical path deflection section for deflecting an optical path by reflection, the optical path deflection section being formed at the predetermined portion of the guide section so as to be in a position intersecting the optical axis of the optical fiber mounted in the guide section,
• wherein the optical fiber placed in the guide section on the optical package substrate is pressed from above by a predetermined substrate, whereby the optical fiber is affixed to the optical package substrate.

An optical device having an optical component and/or optical element mounted on an optical package substrate,

• the optical package substrate comprising:
• a waveguide section as a groove formed on a surface of a substrate and extending from an end face of the substrate to a predetermined portion of the substrate, the waveguide section corresponding to a predetermined optical waveguide core pattern;
• and
• an optical path deflection section for deflecting an optical path by reflection, the optical path deflection section being formed at the predetermined portion of the waveguide section so as to be in a position intersecting an optical axis of the optical waveguide defined in the waveguide section,
• the optical device further comprising a predetermined substrate, wherein a core material having a refractive index higher than a refractive index of the optical package substrate is filled in the waveguide section of the optical package substrate, and thereafter an adhesive having a refractive index lower than the refractive index of the core material is used to attach the predetermined substrate to the waveguide section.

An optical device having an optical component and/or optical element mounted on an optical package substrate,

• the optical package substrate comprising:
• a stage portion for fixing an optical axis of a light receiving/emitting element mounted on the stage portion, the stage portion being formed on a surface of a substrate;
• and
• an optical path deflection section for deflecting an optical path by reflection, the optical path deflection section being formed on the surface of the substrate so as to be in a position intersecting the optical axis of the light receiving/emitting element mounted on the stage portion
• wherein the light receiving/emitting element is affixed to the stage portion on the optical package substrate.
