We report on the generation of photon-number squeezing in higher-order spatio-polarization modes of light. Using a phase-only spatial light modulator, we transform squeezed Gaussian modes into higher-order Laguerre-Gaussian, Hermite-Gaussian and Bessel beams. By appropriate superposition of orthogonal polarizations, beams with a complex spatio-polarization pattern can be achieved. The implementation is straightforward and in particular does not rely on interferometry. The mode conversion is shown to preserve any non-classicality present in the initial Gaussian mode up to linear losses. We thus demonstrate photon number squeezing of more than -1.0 dB in a wide range of higher-order modes.
