Abstract

This chapter covers a broad area within the domain of optical communications, and, specifically, optical wireless communications, as it shares particular features with both RF wireless and optical fiber communications. There are several challenges within the field, concerned with distribution of the optical field, signal bandwidth, and receiver SNR. This chapter examines three specific areas of the technology which address these issues, namely, modulation methods for optical wireless using OFDM, genetic algorithm-based methods for optimisation of the optical fields indoors for power and bandwidth uniformity, and receiver-amplifier techniques for bandwidth and sensitivity maximisation.
