Fotoninio kristalo stop juostos valdymas keičiant lūžio rodiklį / Stop band position shifting by changing refractive index

Fotoninis kristalas sudarytas iš medžiagų su skirtingais lūžio rodikliais. Dėl stop juostos valdymas fotoniniame kristale yra diskutuotinas klausimas.Vienas iš metodų valdyti stop juostą, užpildyti jį skystuoju kristalu. užpildant opalą skystuoju kristalu, buvo sukurtas LC defektas. Keičiant elektrinį laiuką, intervale nuo 1V iki 6V, defektą galima valdyti. defekto poslinkis gautas per 4m.defektas opale juda šviesos greičiu 300 000 km/s, o stop juostoje greitis lygus 0m/s. / Photonic crystals (PCs) are periodic dielectric materials that can control the propagation of photons. Control of stop band position in photonic crystals was discussed.A method was developed to adjust the opal stop band position by controlling the refractive index.When filling in the opal LC the result was a LC defect. Changing the electric field wichin the interval from 1 V to 6 V it is possible handle the defect. The movement of the defect was 4nm. The defect in the opal in moving with light speed that is 300 000 km/s and the speed on the bang is 0 m/s.
