An optical subassembly structure for mode conversion by an active alignment of an optical fiber with a semiconductor optical waveguide includes a sub-mount for holding the optical subassembly structure, a semiconductor die mounting on the sub-mount, the semiconductor optical waveguide growing on the semiconductor die and a glass capillary subassembly actively aligned to the semiconductor optical waveguide.

Optical subassembly structure

An optical module package has a first case, a second case and a fiber unit. The first case has a case bottom-part formed along the length direction of the fiber unit, a bottom convex-part formed on the case bottom-part so as to project toward inside direction of the first case and an elastic support part made of elastic member and covering the bottom convex-part. The optical waveguide device is supported by the elastic support part and the optical fiber is arranged at the distant position from the elastic support part.

Optical module package

The present invention is directed to an assembly of an optical fiber and an optical fiber holder for holding the optical fiber, the optical fiber having an end surface formed at an end portion thereof, the end surface being configured to perform light coupling with a light emitting element or with a light receiving element. The optical fiber holder comprises; a throughhole which extends through the optical fiber holder and a recess that is positioned on a surface of the optical fiber holder and that is provided with an opening of the throughhole. The optical fiber is inserted through the throughhole and an adhesive is filled in a gap between an inner wall of the throughhole and an outer periphery of the optical fiber, the adhesive being used for adhering the optical fiber to the optical fiber holder. The end portion, on which is formed the end surface of the optical fiber, protrudes from the opening and terminates within the recess.
