Publisher Summary This chapter provides a taxonomy of optical modulation formats along
with experimental techniques for realizing them. High-speed optical transmission systems …

This chapter is an introduction to the near-Earth laser communication technology. By near-
Earth, we mean high-altitude platforms and Earth-orbiting satellites. Justification for high …

We designed a photon-counting receiver system for long-distance underwater wireless laser
communication at different code rate Reed-Solomon (RS) and low-density parity check …

Starting with capacity and sensitivity-constrained transport (fiber-optic networks, satellite
links), optics is steadily replacing electronics, progressing into implementation-constrained …

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 …

Challenges of direct-to-Earth (DTE) laser communications (lasercom) between spacecraft in
low-Earth orbit (LEO) or medium-Earth orbit (MEO) and ground terminals can include short …

Communication bottlenecks, particularly in the downlink direction, are a common problem
for many CubeSat developers. As described herein, a CubeSat module for a CubeSat …

Small satellites, particularly CubeSats, have become popular platforms for a wide variety of
scientific, commercial and military remote sensing applications. Inexpensive commercial o …

We present a new class of optical modulation formats based on the combination of m-ary
pulse-position modulation (m-PPM) or m-ary frequency-shift keying (FSK) with additional …

We present the principle, implementation, and performance of a recently introduced high-
sensitivity modulation format based on the combined use of polarization-division …
