Abstract
A light concentrator for an optical antenna gradually narrows from the light receiving end to the end in contact with a light detector, and has a refractive index that gradually increases from the first to the second end, to afford a greater acceptance angle for the incoming optical signal. The increase may occur in stages of corresponding layers of the light concentrator, the layers being arranged in order of increase in refractive index from the first end to the second end.
