Abstract

The present invention relates to an optical coupler having at least one longitudinal axis, said optical coupler comprising a first segment having first cross sections perpendicular to the longitudinal axis and a second segment having second cross sections perpendicular to the longitudinal axis said first and second segments sharing a common border interface, whereinsaid said first segment comprises an internal volume with refractive index nv selected from the group of a filling material, a vo.d or a combination thereof, where said internal volume is tapered whereby it is possible to combine light from multiple fiber with reduced loss of brightness.
