Abstract
A method and apparatus for aligning an optical waveguide with a radiation source are provided. The waveguide has a longitudinal axis that defines a main optical propagation path. The optical waveguide is illuminated by the radiation source such that the waveguide generates light via photoluminescence, at least a portion of the light generated via photoluminescence being emitted from the waveguide along a direction generally transverse to the longitudinal axis. An output signal is generated at least in part on the basis of light emitted from the waveguide along a direction generally transverse to the longitudinal axis. The alignment of the radiation source and the waveguide is varied at least partly in dependence of the output signal.
