OPTICAL SENSOR FOR surface electromagnetic waves Photonic Crystals (OPTIONS)

摘要

1. An optical sensor for surface waves photonic crystals, characterized by the presence of glass or silica prism or cylindrical lens, which is sputtered in vacuo photonic crystal, which is an alternating dielectric layers of equal optical thickness and with different refractive indices in an amount of 10-15 pairs of layers for receiving weakly divergent beam of monochromatic beams of laser light directed at a predetermined angle to excite at the air - the photonic crystal surface ELEKTROM gnitnoy waves. ! 2. An optical sensor according to claim 1, characterized in that the outer layer of the photonic crystal is covered with a layer of dye-type fluorescent substance to render the surface of the electromagnetic wave propagation and the light source and detector are rotated in accord to the condition of excitation and simultaneous detection of the surface wave. ! 3. Optical sensor surface wave photonic crystals, characterized by the presence of glass or silica prism or cylindrical lens, which is sputtered in vacuo photonic crystal, which is an alternating dielectric layers of equal optical thickness and with different refractive indices in an amount of 10-15 pairs of layers for receiving parallel beam of white (broad spectral range) of light directed at a predetermined angle to excite at the air - the photonic crystal surface ELEKTROM agnitnoy wave, the outer layer of the photonic crystal is covered with a layer of functional molecules capable of specifically binding with the test biomolecules. ! 4.
