Abstract
A photonics integrated circuit for processing radiation includes a first-dimensional grating coupler for coupling in radiation, a second two-dimensional grating coupler for coupling out radiation and a waveguide structure having two distinct waveguide arms for splitting radiation received from the first grating coupler and recombining radiation in the second grating coupler. A phase shifting means furthermore is provided for inducing an additional phase shift in at least one of the two distinct waveguide arms thereby inducing a relative phase shift of π between the two distinct waveguide arms so as to provide a TE/TM polarization switch for radiation between the first grating coupler and the second grating coupler.
