Eo modulator Series: Umuvuduko mwinshi, voltage nkeya, igikoresho gito gipima polarisation ya lithium niobate

Umuhuzabikorwa wa EoUrukurikirane: Umuvuduko mwinshi, voltage nkeya, igikoresho gito cyo kugenzura polarisation ya litiyumu niobate

Imiraba y'urumuri iri mu mwanya wigenga (kimwe n'imiraba y'amashanyarazi y'indi miyoboro) ni imiraba yo gukata, kandi icyerekezo cy'ihindagurika ry'imbaraga zayo z'amashanyarazi na rukuruzi gifite icyerekezo gitandukanye gishoboka mu gice cy'uruziga kijyanye n'icyerekezo cy'ikwirakwira, ari na yo miterere y'urumuri. Polarization ifite akamaro kanini mu bijyanye n'itumanaho ry'urumuri, gupima inganda, ubuvuzi bw'ibinyabuzima, kumenya kure y'isi, igisirikare cya none, indege n'inyanja.

Mu bidukikije, kugira ngo birusheho kugenda neza, ibinyabuzima byinshi byahinduye uburyo bwo kubona bushobora gutandukanya imiterere y'urumuri. Urugero, inzuki zifite amaso atanu (amaso atatu y'umwe, amaso abiri y'inyongera), buri imwe muri zo ikaba irimo amaso 6.300 mato, afasha inzuki kubona ikarita y'imiterere y'urumuri mu mpande zose z'ikirere. Uruyuki rushobora gukoresha ikarita y'imiterere y'urumuri kugira ngo rubone kandi ruyobore neza ubwoko bwarwo ku ndabyo rubonye. Abantu ntibafite ingingo z'umubiri zisa n'iz'inzuki kugira ngo bumve imiterere y'urumuri, kandi bakeneye gukoresha ibikoresho by'ubukorikori kugira ngo bumve kandi bukoreshe imiterere y'urumuri. Urugero rusanzwe ni ugukoresha indorerwamo zihuza urumuri kugira ngo ruyobore urumuri ruturutse ku mashusho atandukanye mu maso y'ibumoso n'ay'iburyo mu imiterere y'urumuri, ari na yo ngingo ngenderwaho ya filime za 3D muri sinema.

Iterambere ry'ibikoresho byo kugenzura imiterere y'urumuri rw'amashanyarazi bifite imikorere myiza ni ingenzi mu guteza imbere ikoranabuhanga ryo gukoresha urumuri rw'amashanyarazi. Ibikoresho bisanzwe byo kugenzura imiterere y'urumuri birimo icyuma gitanga imiterere y'urumuri rw'amashanyarazi, scrambler, polarization analyzer, polarization controller, nibindi. Mu myaka ya vuba aha, ikoranabuhanga ryo gukoresha imiterere y'urumuri rw'amashanyarazi riri kwihutisha iterambere no kwinjira mu bice byinshi by'ingenzi bishya.

Kujyanaitumanaho ry'amasourugero, bitewe n'ibyifuzo byo kohereza amakuru menshi mu bigo by'amakuru, uburyo bwo gukora intera ndendeitara ry'amasoIkoranabuhanga mu itumanaho riri kugenda rikwirakwira buhoro buhoro mu buryo bwo guhuza ikoranabuhanga mu ntera ngufi, bushobora kwibasirwa cyane n’ikiguzi n’ingufu, kandi gukoresha ikoranabuhanga ryo guhindura ikoranabuhanga mu gukwirakwiza amashanyarazi bishobora kugabanya ikiguzi n’ingufu bya sisitemu z’itumanaho zihuza ikoranabuhanga mu ntera ngufi. Ariko, muri iki gihe, kugenzura amashanyarazi bikorwa ahanini hakoreshejwe ibice bitandukanye by’ikoranabuhanga, ibyo bikaba bibangamira cyane kunoza imikorere no kugabanya ikiguzi. Hamwe n’iterambere ryihuse ry’ikoranabuhanga ryo guhuza ikoranabuhanga mu by’ikoranabuhanga, guhuza ikoranabuhanga na chip ni ingenzi mu iterambere ry’ibikoresho bigenzura amashanyarazi mu ntera ngufi mu gihe kizaza.
Ariko, utuyobora tw’amashanyarazi twakozwe mu tubuye dusanzwe twa lithium niobate dufite ingaruka mbi zo kuba duto cyane kandi ubushobozi bwo gufatanya n’amashanyarazi bugabanuka. Ku ruhande rumwe, ingano y’igikoresho ni nini, kandi biragoye guhaza ibyifuzo byo gushyira hamwe. Ku rundi ruhande, uburyo amashanyarazi akoreshwa mu gupima urumuri ni buke, kandi ingufu z’amashanyarazi zitwara igikoresho ni nyinshi.

Mu myaka ya vuba aha,ibikoresho byo gufotoraibikoresho bya firime nto ya lithium niobate byateye imbere mu mateka, bigera ku muvuduko mwinshi no kugabanuka k'umuvuduko ugereranije n'ibya kera.ibikoresho bya litiyumu niobate fotonike, bityo barakundwa n'inganda. Mu bushakashatsi buherutse gukorwa, chip ihuriweho ya polarization control chip ikoreshwa kuri platform ya lithium niobate thin film photonic integration, harimo generator polarization, scrambler, polarization analyzer, polarization controller n'izindi nshingano z'ingenzi. Ibipimo by'ingenzi by'izi chips, nko kwihuta kwa polarization, quantity ya polarization, polarization perturbation speed, hamwe n'umuvuduko wo gupima, byashyizeho amateka mashya ku isi, kandi byagaragaje imikorere myiza mu muvuduko mwinshi, ku giciro gito, nta gutakaza kwa parasite modulation, ndetse na voltage nkeya yo gutwara. Ibyavuye mu bushakashatsi ku nshuro ya mbere bigaragaza urukurikirane rw'imikorere myiza.lithiyumu niobateIbikoresho byo kugenzura polarisation y'urumuri rw'urumuri rworoheje, bigizwe n'ibice bibiri by'ibanze: 1. Kuzunguruka/gutandukanya polarisation, 2. Interferometer ya Mach-zindel (ibisobanuro >), nk'uko bigaragara ku Ishusho ya 1.
