Abstract

We propose a scheme for designing a new optical receiving system that can reduce the received-energy spot size via integration of a compound parabolic concentrator with a hemispherical lens. SolidWorks is used to model the receiving system, while TracePro is employed for simulations. The field of view is set to 30° and the radius of the compound parabolic concentrator outlet is 5 mm, which is also the radius of the hemispherical lens. Ray-tracing results show that under the given simulation conditions, the radius of the spot area is reduced from 5 to 3 mm at the receiving system and the gain is 5.2. In regard to the relations between received power and the radius of the hemispherical lens $R$, and the received power and the distance $d$ between the compound parabolic concentrator and hemispherical lens, our detailed analysis yields the following characteristics: (1) the received power increases as $R$ increases, but decreases as $d$ increases; (2) as $R$ increases, the spot area increases and the received flux is dispersed over the receiving plane, which dispersion is disadvantageous for high-speed communication; (3) the gain of the receiving system also varies with $R$ and $d$; (4) an increase in $d$ leads to decrease in the received flux and gain when $d>-2\mathrm{mm}$. Based on these characteristics, we set $R=5\mathrm{mm}$ and calculate the energy efficiency. We obtain maximum energy efficiencies for different detection areas.
