Abstract

Spectral slicing of a broadband LED source is an efficient method for providing multiple wavelength channels for WDM sensor networking. However, optical power budgetary considerations limit the numbers that can be accommodated even with the use of power efficient topologies. Very recently, extended spectral width broadband LEDs have become available which provide spectral widths greater than 120 nm. Such LED devices exhibit both power output and spectral width capabilities comparable with the combined effect of two or three conventional LEDs. This paper reports on an investigation of the performance of such devices in relation to their utilization within WDM point-sensor networks. Furthermore, specific available device characteristics are utilized within a WDM sensor network modeling process in order to determine the maximum number of sensors that can be accommodated on various power efficient topologies. Hence, it is demonstrated that the use of these very broadband LED sources can facilitate significantly larger numbers of sensors than may be accommodated by employing spectral slicing of conventional LEDs.
