AB - The PT-symmetric optical grating with index profile e2ibz has been shown to have the interestingproperty of being essentially invisible for light incident from one side, while possessing greatlyenhanced reflection at a particular wavelength for light incident from the other side. We extend aprevious analysis of this grating to obtain an analytic solution for the case when the grating isembedded on a substrate, with different refractive indices on either side. We also generalize theprevious case of normal incidence to incidence at an arbitrary angle. In that case the enhancedreflection occurs at a particular angle of incidence for a given wavelength. Finally we discusshow the grating may be used to give lasing.
