Abstract

We have already used interferometric techniques for measuring, first, the impulse response of optical fibres and further the different times of flight of modes of a multimode fibre. Apart from time of flight, our set-up provides the intramodal dispersion of each mode (d2β/dω2). To demonstrate, we have measured the modal dispersion difference between two tubular modes that were selectively excited in a multimode graded index fibre. For comparison, a theoretical expression has been derived, based on a ray optics approach.
