We show a new possibility for extension of supercontinuum spectrum generated in photonic crystal fibre towards the UV light. To do so, we use four wave mixing and cross phase modulation nonlinear effects as well as interaction of fundamental mode with higher order modes. It is shown that a few modes operation and proper dispersion profiles of these modes give a possibility of nonlinear effects optimization and thus improvement of UV generation. The advantage of presented solution is the employment of cascaded nonlinear interactions inside one microstructured fibre.
