ENHANCED COUPLING ARRANGEMENT FOR AN OPTOELECTRONIC TRANSDUCER

摘要

A COUPLING ARRANGEMENT INCLUDES A VERTICAL CAVITY SURFACE EMITTING LASER. A CARRIER (22) HAS THE VERTICAL CAVITY SURFACE EMITTING LASER AFFIXED THERETO. AN OPTICAL COUPLER (26) IS COUPLED TO THE VERTICAL CAVITY SURFACE EMITTING LASER, AND HAS A PLURALITY OF OPTICAL FIBERS (38) WHICH RECEIVE LIGHT EMITTED FROM THE VERTICAL CAVITY SURFACE EMITTING LASER. THE VERTICAL CAVITY SURFACE EMITTING LASER IS SEPARATED FROM THE OPTICAL COUPLER BY A GAP (30) AND IS FREE OF DIRECT CONTACT WITH THE OPTICAL COUPLER. THE GAP IS LESS THAN ABOUT 50 MICRONS, AND IS GREATER THAN ZERO MICRONS. A CURABLE ADHESIVE (28) IS DISPOSED IN THE GAP FOR COUPLING THE VERTICAL CAVITY SURFACE EMITTING LASER TO THE OPTICAL COUPLER. THE ADHESIVE HAS A VISCOSITY THAT DEFINES A SIZE OF THE GAP.(FIG. 3)
