Query: Emergence of transverse spin in optical modes of semiconductor nanowires   The transverse spin angular momentum of light has recently received
tremendous attention as it adds a new degree of freedom for controlling
light-matter interactions. In this work we demonstrate the generation of
transverse spin angular momentum by the weakly-guided mode of semiconductor
nanowires. The evanescent field of these modes in combination with the
transversality condition rigorously accounts for the occurrence of transverse
spin angular momentum. The intriguing and nontrivial spin properties of optical
modes in semiconductor nanowires are of high interest for a broad range of new
applications including chiral optical trapping, quantum information processing,
and nanophotonic circuitry.
