In-line optoelectronic device packaging
View Patent ↗A fiber connector that facilitates alignment of and electrical communication with electrooptical devices on an optical fiber or interposed between optical fibers. An embodiment of in-line optoelectronic device packaging constructed according to principles of the invention includes a ferrule configured to receive an optical fiber with an optoelectronic device mounted on one end of the ferrule, for alignment with the fiber. Electrically-conductive deposits along the side of the ferrule supply electrical energy to or conduct electrical signals from the optoelectronic device. The optoelectronic device-carrying ferrule is inserted in a ceramic sleeve. Another ferrule, maintaining another optical fiber, also is inserted in the ceramic sleeve. Another embodiment constructed according to principles of the invention includes a second optoelectronic device mounted on the second ferrule. The electrically-conductive deposits permit ready serial deployment of optoelectronic devices between the optical fibers maintained by the ferrules in the sleeve.
1. An optoelectronic assembly adapted to be interposed between optical fibers comprising:
a ferrule having a first end and a second end;
an optoelectronic device mounted on said first end of said ferrule;
a plurality of electrical conductors mounted on said ferrule from a first portion to a second portion, said first portion configured at said first end of the ferrule and said second portion configured a first given distance from said first end of said ferrule toward said second end of said ferrule, each said electrical conductor being electrically insulated from adjacent ones of said electrical conductors, said electrical conductors enabling communication of electrical signals from said optoelectronic device;
a sleeve configured to receive said first end of said ferrule therein to a second given distance, wherein said second given distance is less than said first given distance so as to position said second portion outside of said sleeve; and
an energy supply selectably electrically connectable to ones of said electrical conductors at said second portion outside of said sleeve.
2. The ferrule of claim 1 , wherein each said electrical conductor is an electrically-conductive film.
3. The ferrule of claim 1 , wherein each said electrical conductor is constructed from metal.
4. The ferrule of claim 1 , including a plurality of electrical connectors, each connected to selected ones of said electrical conductors, enabling electrical communication with the optoelectronic device, a feed-through, a socket and combinations thereof.
5. The assembly of claim 1 , said optoelectric device being selected from a detector, a filter, a laser source, a sensor, a VCSEL, a CCD, an optical modulator, a variable attenuator and combinations thereof.
6. The assembly of claim 1 , further comprising:
a second ferrule;
said sleeve being configured to receive said second ferrule.
7. The assembly of claim 6 , said optoelectronic device being interposed between said ferrule and said second ferrule.
8. The assembly of claim 6 , further comprising a second optoelectronic device mounted on said second ferrule;
said second ferrule including a second plurality of electrical conductors enabling electrical communication with said second optoelectronic device.
9. The assembly of claim 8 , said second optoelectronic device being interposed between said ferrule and said second ferrule.
10. The assembly of claim 8 , said second optoelectronic device being selected from a detector, a filter, a laser source, a sensor, a VCSEL, a CCD, an optical modulator, a variable attenuator and combinations thereof.
11. The assembly of claim 8 , further comprising a second energy supply selectably electrically connectable to ones of said second plurality of electrical conductors.
