Transmission Spectrum Transformation At Photonic Hetero-Crystal Interfaces - Polarization Anisotropy
Validated
1
()
Optional Fields
Photonic hetero-crystals composed from thin film colloidal crystals of different topology demonstrate the non-trivial transformation of the spectrum of transmitted light, which goes far beyond the superposition of transmissions of single films. This transformation relates to the light Coupling conditions at the PBG interface and becomes the most pronounced, if matching takes place between low and high order photonic bands.. This spectrum transformation leads to peculiar changes of the polarisation anisotropy of the light propagating at oblique incidence and, provisionally, to the non-reciprocity of the light polarisation composition with respect to reversing the light propagation direction..
