An effective method for producing arrays of nanoscale triangles, rods and wells on the distal end of a silica optical fibre is presented. The structures are produced by applying a wet‐etch procedure to drawn‐down imaging fibres. Structural variation is achieved by altering the final diameter of the drawn fibre. Feature sizes of less than 100 nm can be readily achieved in this way. When coated with silver, surface‐enhanced Raman scattering enhancement factors of over 10 6 can be achieved, depending on the size and shape of the structures present.
