“…Healey was the first to analyze this in the communications context in 1987 [33] and then Chu and Dickey published a more comprehensive analysis based on continuous-wave light [34]. The Stanford group had studied the origins of the same noise, optical beat noise, in great detail in relation to multiplexing interferometric sensors [22,35]. It would later be studied in relation to spectrum-sliced wavelength division multiplexing systems as well (see below).…”

In this paper, an overview of author's research is presented, commencing at the University of Kent under Prof. David A. Jackson. Early research in short optical pulses and fiber-optic delay-line digital correlators led to optical communications research in code-division multiple access networking. This research was based on broadband incoherent light, and this theme continued with research into spectrum-sliced wavelength-division multiplexing. In shifting from photonics research to biomedical optics and biophotonics in the late 1990s, the emphasis on exploiting broadband light continued with research in optical coherence tomography, amongst other topics. In addition to the research outcomes, how these outcomes were attained is described, including mention of the exceptional contributions of many of my colleagues.

“…This noise is caused by the two beams recirculating the same times in the optical loop, and its intensity and the autocorrelation function of , , are given as (12) (13) where is the spectral linewidth of the light source. In (13), the term is caused by the phase fluctuation of the optical beam [8], [11], [12] with the assumptions described Next, we concern to the noise intensity at Hz . This noise is caused by the two beams whose recirculation numbers in the loop are different by -times.…”

“…Three different types of the multiplexing scheme have been investigated, which are the time division multiplexing [1]- [2], the frequency division multiplexing [3]- [5], and the coherence multiplexing [6]- [8]. The coherence multiplexed sensor system is composed of a light source, a set of sensing interferometers whose optical path differences (OPD's) are different each other, and a corresponding set of receiving interferometers.…”

“…Cielo and Delisle also proposed how several coherencemodulated channels can be multiplexed in a common optical transmission fiber, by cascading multiple coherence modulators and using a common optical source [2]. Some alternatives were proposed by Brooks et al [3], and analyzed by Wentworth [6], for application in an optical interferometric sensor system. Apart from the serial configuration, which they termed the discontinuous series (DS) system, they proposed the continuous series (CS) system, the extrinsic reference ladder (ERL) system, and the intrinsic reference ladder (IRL) system.…”

Coherence multiplexing is a potentially inexpensive form of optical code-division multiple access, which is particularly suitable for short-range applications with moderate bandwidth requirements, such as access networks, LANs, or interconnects. Various topologies are known for constructing an optical transmission system in which several channels are coherence-multiplexed in one optical fiber. In this paper, the parallel array, the intrinsic reference ladder (IRL), and the discontinuous series system topologies will be further considered and compared with respect to code orthogonality requirements, theoretical performance, and some practical implementation aspects. A modification to the IRL system is proposed, resulting in a significant improvement in the theoretical performance.Index Terms-Coherence multiplexing (CM), noise analysis, optical code-division multiple access (OCDMA), optical communication, optical network topologies.
