“…Hybrid APD-HEMT optical receivers for 10 Gbps systems with a sensitivity of -29.4 dBm at a bit-error rate of iO have been presented in [14]. Resonant cavity SAM APDs with gainbandwidth products 130 GHz, QE of 75%, low dark current, low multiplication noise and breakdown voltages less than 15 V were described in [15].…”

This paper presents an brief overview of some of the common high-speed and high-sensitivity photodetectors. These devices are the key components in long-haul, high bit-rate fiber optic communication systems. In this paper, while we describe several types of photodetectors, we concentrate on avalanche photodiodes since they are the current preferred candidates for high bit-rate long-haul fiber optic communication systems. We describe and compare some analytical and stochastic modeling results with experimental data and conclude with a discussion of some state-of-the-art results on photodetectors.

“…At rates of 10 Gbps, M =∼3 to 10, and F APD =∼4, providing about a 10-dB benefit over PIN-receivers, with 10 −9 BER achieved for -29 dBm or ∼1000 PPB receiver sensitivity (see, e.g., [388,389]). At lower rates-less than 1 Gbps, APDs have demonstrated performance in the 100 to 200 PPB regime [390][391][392].…”

Free-space laser communication systems have the potential to provide flexible, high-speed connectivity suitable for long-haul intersatellite and deep-space links. For these applications, power-efficient transmitter and receiver designs are essential for cost-effective implementation. State-of-the-art designs can leverage many of the recent advances in optical communication technologies that have led to global wideband fiber-optic networks with multiple Tbit/s capacities. While spectral efficiency has long been a key design parameter in the telecommunications industry, the many THz of excess channel bandwidth in the optical regime can be used to improve receiver sensitivities where photon efficiency is a design driver. Furthermore, the combination of excess bandwidth and average-power-limited optical transmitters has led to a new paradigm in transmitter and receiver design that can extend optimized performance of a single receiver to accommodate multiple data rates. This paper discusses state-of-the-art optical transmitter and receiver designs that are particularly well suited for average-power-limited photon-starved links where channel bandwidth is readily available. For comparison, relatively simple direct-detection systems used in short terrestrial or fiber optic links are discussed, but emphasis is placed on mature high-performance photon-efficient systems and commercially available technologies suitable for operation in space. The fundamental characteristics of optical sources, modulators, amplifiers, detectors, and associated noise sources are reviewed along with some of the unique properties that distinguish laser communication systems and components from their RF counterparts. Also addressed is the interplay between modulation format, transmitter waveform, and receiver design, as well as practical tradeoffs and implementation considerations that arise from using various technologies.

“…The optical power at a BER was -28.8 dBm with a pseudo random bit stream (PRBS) signal length of 223-l. This is the highest sensitivity so far reported for IO-Gb/s-APD receivers [8,9].…”
