Optical coupling for optical fibers

A system for coupling a laser to an optical fiber, comprising:

• a housing;
• a laser contained within said housing for providing radiation in a plurality of optical modes;
• and
• a parabolic optical concentrator contained within said housing for concentrating said plurality of optical modes;
• a scattering surface formed on said parabolic optical concentrator, wherein said plurality of optical modes associated with said laser are scrambled utilizing the scattering surface after being concentrated by said optical concentrator;
• and
• an optical fiber receiver formed in said housing for receiving and coupling an optical fiber in a manner whereby said plurality of optical modes are focused onto a fiber facet associated with said optical fiber after passing through said optical concentrator.

An optical coupler including a vertical cavity surface emitting laser (VCSEL), comprising:

• a housing for coupling an optical fiber having a core to a VCSEL and having an opening for receiving said optical fiber;
• a VCSEL contained in said housing;
• and
• an parabolic optical concentrator formed within said housing and disposed between said VCSEL and said opening, wherein a plurality of optical modes provided as a signal from said VCSEL are concentrated utilizing said parabolic optical concentrator as laser light from said VCSEL is focused on a fiber facet associated with said optical fiber;
• and
• a scattering surface formed on said parabolic optical concentrator between said parabolic optical and said optical fiber wherein said plurality of optical modes are scrambled during transmission through said optical scattering surface.
