A new interpretation of spot size measurements on singly-clad single-mode fibres

Abstract

By using the Petermann spot size rather than the Marcuse spot size we suggest a slight modification to the Millar method for ESI determination which will allow the three parameters necessary for the EESI to be determined. The method is particularly useful for triangular-profile fibres.
