Paper Abstract

It is suggested that multimode slab waveguide spectrographs currently under development for wavelength division multiplexing in optical communications might have an application in astronomy. The nature of these devices is described, and a survey of their development in the communications industry presented. The applicability of existing devices is investigated and found to be limited. However, it is shown that only a modest improvement in resolution (factor of 2-4), together with a realization of the potentially very high optical efficiency, could yield an astronomically useful device. The anticipated problems in developing such as instrument are outlined.
