Nanobiophotonics of biological and biomimetical optical materials
The transmission of light by spicules of marine glass sponges and monolithic nanocomposite silica biomaterials synthesized on the basis of natural polysaccharides has been experimentally investigated. Our researches have shown that the core diameter and cladding layers thickness of the spicules of glass sponges are appropriate to cause photonic bandgaps. This enables singlemode waveguide and Bragg light propagation regimes in the spicules. The strong non-linear optical properties of glass sponges and nanocomposite silica bioma terials have been revealed in spectral characteristics of transmitted ultra-short laser pulses. The shape of transmitted spectrums through beth spicules and nanocomposite biomaterials demonstrates major changes indicating the broadening and formation of dip due to self-phase modulation along with formation markedly strong anti-Stokes component in the output spectrum with generation of supercontinuum spectra.
