Abstract
Many types of broadband optical communications system rely on the transmission of information at several carrier wavelengths which are then separated at the receiver. High performance wavelength selective components are crucial to the operation of such systems. Here we report the development of an in-line fiber-optic wavelength selective element that is capable of selecting a single wavelength channel from a fiber with high resolution (down to a few nanometers) and coupling it directly to a receiver or into a second fiber, whilst all remaining channels are transmitted with low loss.
