摘要： The present disclosure is directed to an optically active medium comprising dye aggregates and optionally a nucleotide oligomer or other nucleotide-based architecture, which may be used in in optical devices, in particular nonreciprocal devices (i.e., devices in which energy flows in one direction only), that can respond to differences in the polarization of light. An analysis is presented of the energy levels and the strengths of the optical transitions (changes in energy states) for a three-chromophore (dye) aggregate in which the chromophores are coupled with a J-like (i.e., end-to-end) stacking. Specific devices and methods of use are also disclosed herein.

摘要： A photonic crystal structure employs such a structure that two layers having different refractive indices are laminated alternately, a polymer including a structure unit derived from a monomer that contains a fluorocarbon group being used for one of the repeated layers such that the photonic crystal structure can respond to humidity and/or organic solvent concentration. Using the photonic crystal structure, it is possible to manufacture a color-conversion photonic crystal sensor having excellent sensitivity and reproduction characteristics.
