发明名称 OPTICAL ANTENNA AND WIRELESS OPTICAL SYSTEM USING THE SAME
摘要 A light concentrator (210) for an optical antenna (200) gradually narrows from the light receiving end (210a) to the end (210b) in contact with a light detector (220), 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 (211-1...211-n) of the light concentrator (210), the layers being arranged in order of increase in refractive index from the first end to the second end. <IMAGE>
