“…Sinusoidal-drive techniques have also been used for ultra-high-speed serial-parallel conversion in optical time-division multiplexed (OTDM) systems [337] and photonic analog-to-digital converters [338]. Pulse carving reduces the influence of imperfections in the drive electronics, such as transient ringing, pattern dependence and inadequate bandwidth, on waveform quality.…”

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.

“…It was shown that 40GHz modulation of the 160 Gb/s signal manipulates the phase change over consecutive pulses in such a way to allow a 40 Gb/s channel to be discriminated by optical filtering. By similar principle, 2:1 demultplexing of 100 Gb/s signal has been shown using a phase modulator connected in a fiber loop [9], however in contrast to the filtering technique, this method requires cascading two modulators driven at different harmonic frequencies to enable equivalent 4:1 demultiplexing. Directly cascading LiNbO3 amplitude modulators for demultiplexing has also been reported whereby the delay between modulators is adjusted so that the combined switching response produces a shorter gating window [10].…”

“…For fiber transmission rate up to tens of gigabits per second, however, the required S/P ratio will be up to hundreds or more. At the moment, only converters of small S/P ratio such as 16 are practical [6], [7]. New approaches of electronic buffering with data conversion rate much slower than the fiber transmission rate are therefore necessary to avoid the data conversion bottleneck.…”
