Abstract
Isolated pulsars are ideal sources for polarisation studies since the radiation from pulsars generally covers a wide range of wavelengths from radio to very-high-energy γ-rays and the pulsed emission is closely tied to the local magnetic field direction. Although radio polarisation data exist for many pulsars, polarisation measurements at higher energies exist for only six sources. All six of these have optical polarisation measurements while only the Crab pulsar has measured polarisation in the X-ray band. One member of a small group of pulsars only visible at optical and X-ray wavelengths, thought to be powered by thermal emission from the cooling neutron star surface, has detected optical polarisation. This chapter will review the current multi-wavelength polarisation observations and the theoretical modelling by which we can probe the pulsar magnetosphere structure and emission mechanisms.
