Abstract
The dependence of the nonlinear coefficients on the transverse profiles of the pump and the probe
fields, which is especially important for a highly anisotropic device such as the Al
$_{\bf 0.18}$
Ga
$_{\bf 0.82}$
As waveguide, was not
explicitly stated in our paper “Data transfer from RZ-OOK to RZ-BPSK by polarization-insensitive XPM in a
passive birefringent nonlinear AlGaAs waveguide.” The four-wave mixing efficiency was also incorrectly presented
to depend on the square of the device physical length. Lastly, the influence of the fiber-waveguide coupling
coefficient was neglected with insufficient justification, leading to an inaccurate general expression for the
detected voltage.
