Description/Abstract
Optical filtering is perhaps one of the most basic signal-processing functions and consequently finds a wide variety of applications throughout the field of optical telecommunications, sensing and signal processing. With the growing complexity of fibre circuitry, the fibre-based filter has become increasingly-important with its obvious advantages of compatibility and low interconnection loss. Over the years numerous relatively-broadband fibre filters have been developed for applications which require filtering of widely-separated wavelength channels, mostly based on some form of intermodal interference (e.g. twin-core, birefringent, or interferometric devices). More recently, interest in coherent transmission and fine-grain wavelength-division-multiplexed (WDM) systems (which require sub-megahertz laser linewidth and channel spacings of a few gigahertz) has emphasised the need for narrowband fibre filters with linewidths of less than 1nm.
