Abstract
An optoelectronic semiconductor device for use in an optical transmission system comprises a stem for mounting an optoelectronic semiconductor element thereon and a cap within which an optical fiber, optically communicating with the optoelectronic semiconductor element, is arranged. An end of the optical fiber within the cap is exposed on the cap surface. A screw is formed on the outer suface of the cap and a nut, which engages the screw, is provided for optically connecting optical transmission fiber with the optical fiber within the cap.
Claims15
An optoelectronic semiconductor device for optical connection with an optical transmission fiber comprising:
- (a) an optoelectronic semiconductor element;
- (b) a stem for mounting the optoelectronic semiconductor thereon;
- (c) an optical fiber optically communicating with the optoelectronic semiconductor element;
- (d) a cap secured to the stem for containing the optical fiber therein;
- (e) a projection formed on the top portion of the cap and wherein the face of a first end of the optical fiber is exposed on the top surface of the projection and the face of a second end of the optical fiber is positioned adjacent the optoelectronic semiconductor element;
- (f) a screw formed on the external side surfaces of the cap;
- and
- (g) nut means engageable with the screw for optically connecting the optical transmission fiber to the optical fiber, wherein said nut means comprises (i) a hollow nut member having an inner threaded portion for engagement with the screw and (ii) an inside member provided inside the hollow nut member, secured to an end of the optical transmission fiber, and having a recess formed in the inside member in a shape compatible with the shape of the projection for mating with and insertion of the projection therein.
