“…This development led to their use in other sensing systems including Faraday-effect electric current sensors and distributed Bragg-grating sensor systems [7]. This was soon followed in the 1990s with their application to the testing of telecommunications wavelength division multiplexing systems [17] and various low coherence interferometry systems including OCT due to their small size, ease of use, low cost, and ten-fold improvement (10 mW) in the output power at that time [7].…”

Using a low coherence interferometry (LCI) model, a comparison of broadband single-Gaussian and multi-Gaussian light sources has been undertaken. For single-Gaussian sources, the axial resolution improves with the source bandwidth, confirming the coherence length relation that the resolution for single Gaussian sources improves with increasing spectral bandwidth. However, narrow bandwidth light sources result in interferograms with overlapping strata peaks and the loss of individual strata information. For multiple-Gaussian sources with the same bandwidth, spectral side lobes increase, reducing A-scan reliability to show accurate layer information without eliminating the side lobes. The simulations show the conditions needed for the resolution of strata information for broadband light sources using both single and multiple Gaussian models. The potential to use the model to study optical coherence tomography (OCT) light sources including super luminescent diodes (SLDs), as reviewed in this paper, as well as optical delay lines and sample structures could better characterize these LCI and OCT elements. Forecasting misinformation in the interferogram may allow preliminary corrections. With improvement to the LCI-OCT model, more applications are envisaged.

“…The spectrum-sliced ASE of SOA could be used as light source for DWDM system rather than separate wavelengthselected distributed feedback (DFB) laser and has been applied in some experimental communication systems [3][4][5]. In this paper, a new configuration is presented, and the corresponding devices are developed.…”

Optical network based on wavelength-division multiplexing (WDM) technology will be a most active research topic in the 21st century. This paper describes a WDM multiple-wavelength transmitter and several key corresponding devices for optical network, including amplified spontaneous emission (ASE) spectrum-sliced multiple-wavelength optical source, optical add/drop multiplexer (OADM), semiconductor optical amplifier (SOA), as well as the spectrum noise suppression scheme. The new research results are reported, and the applications of these developed devices are also introduced.

“…Slicing broadband light had been proposed in the 1980s as an effective means of low-cost wavelength-division multiplexing (WDM) [43]. I started working with my PhD student Warwick Holloway on this and we were one of the first groups to demonstrate how different dopants in erbium-doped fiber could be employed to produce, in our case, a flat spectrum for sliced WDM channels [44] and not for gain flattening per se [45] -this work was presented postdeadline at the the Optical Society of America's Optical Amplifiers and Their Applications Topical Meeting in Breckenridge, Colorado in 1994 (Fig. 5).…”

“…spectrum-sliced channels. After [44] Throughout this period, I had maintained an unhealthy interest in the properties of semiconductor lasers, especially under gain switching, and published a number of papers in this area beginning with the noise and coherence properties of Fabry-Perot lasers elegantly worked out by Robert Griffin at Kent [55], and including data transmission at high bit rates [56] and the reduction of timing jitter in gain switching by continuous-wave (CW) injection [57].…”

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.
