The authors report on high-speed, very large-area, visible light photoreceivers suitable for large-core 1 mm polymer optical fibers (POF). The receivers are based on metal-semiconductor-metal photodetectors (MSM-PD) grown on gallium-arsenide (GaAs) substrate. Three active diameters of, circle divide 1000 mu m circle divide 700 mu m and circle divide 400 mu m were fabricated in order to meet the requirements of the following three specific POF applications. %26lt;br%26gt;The first photoreceiver was designed to characterize the bandwidth of 1 mm POF. For that reason the receiver has an active diameter of circle divide 1000 mu m to detect all modes at the end of the fiber. With this receiver the frequency response of 1 mm graded-index (GI-) POF was measured up to 12 GHz. %26lt;br%26gt;The circle divide 700 mu m photoreceiver was designed for high-speed data transmission. Due to the large active area there is no need for an optical concentrator and the 1 mm POF can simply be butt-coupled to the receiver. With this receiver a novel real-time transmission of 10 Gb/s over up to 20 m GI-POF using simple non return to zero (NRZ) modulation is presented. %26lt;br%26gt;For data rates beyond 10 Gb/s the circle divide 400 mu m photoreceiver with a 3-dB bandwidth of 11 GHz was designed. A record bit rate of 32 Gb/s was transmitted with this receiver over large-core 1 mm polymethylmethacrylate (PMMA) GI-POF. %26lt;br%26gt;These achieved results are by far the best reported values for large-area visible light photoreceivers.
