Abstract:
A multichannel optical coupler can include an output optical coupler array and a plurality of optical fibers. At least two of the plurality of optical fibers can be connected together at an end opposite the output optical coupler array.

Claim (Index 4):
The multichannel optical coupler of  claim 3 , wherein the output optical coupler array comprises:\n an elongated optical element having a first end operable to optically couple with said plurality of optical fibers and a second end operable to optically couple with an optical device, and comprising:\n a common single coupler housing structure; a plurality of longitudinal waveguides each positioned at a predetermined spacing from one another, each having a capacity for at least one optical mode of a predetermined mode field profile, each embedded in said common single housing structure proximally to said second end, wherein at least one of said plurality of longitudinal waveguides is a vanishing core waveguide, each said at least one vanishing core waveguide comprising:\n an inner vanishing core, having a first refractive index (N-1), and having a first inner core size (ICS-1) at said first end, and a second inner core size (ICS-2) at said second end; an outer core, longitudinally surrounding said inner core, having a second refractive index (N-2), and having a first outer core size (OCS-1) at said first end, and a second outer core size (OCS-2) at said second end, and an outer cladding, longitudinally surrounding said outer core, having a third refractive index (N-3), a first cladding size at said first end, and a second cladding size at said second end; and wherein said common single coupler housing structure comprises a transversely contiguous medium having a fourth refractive index (N-4) surrounding said plurality of longitudinal waveguides, wherein a predetermined relative magnitude relationship between said first, second, third and fourth refractive indices (N-1, N-2, N-3, and N-4, respectively), comprises the following magnitude relationship: (N-1>N-2>N-3), \n \n wherein a total volume of said medium or said common single coupler housing structure, is greater than a total volume or all said vanishing core waveguides inner cores and said outer cores confined within said common single coupler housing structure, and wherein said first inner vanishing core size (ICS-1), said first outer core size (OCS-1), and said predetermined spacing between said plurality of longitudinal waveguides, are simultaneously and gradually reduced, in accordance with a predetermined reduction profile, between said first end and said second end along said optical element, until said second inner vanishing core size (ICS-2) and said second outer core size (OCS-2) are reached, wherein said second inner vanishing core size (ICS-2) is selected to be insufficient to guide light therethrough, and said second outer core size (OCS-2) is selected to be sufficient to guide at least one optical mode, such that:\n light traveling from said first end to said second end escapes from said inner vanishing core into said corresponding outer core proximally to said second end, and light traveling from said second end to said first end moves from said outer core into said corresponding inner vanishing core proximally to said first end.
