Igikoresho cy'ingufu z'amashanyarazi gikoresha amashanyarazi (electro-optic modulator) ni iki? Igice cya Kabiri

02modulator y'amashanyarazi n'amataranamodulation ya electro-optiqueigitambaro cy'amajwi

Ingaruka za Electro-optical bivuze ingaruka ikigereranyo cya refractive y'ikintu gihinduka iyo amashanyarazi akoreshejwe. Hari ubwoko bubiri bw'ingenzi bw'ingaruka za electro-optical, bumwe ni ingaruka za electro-optical z'ibanze, zizwi kandi nka Pokels effect, bivuze impinduka y'umurongo w'ikigereranyo cya refractive y'ikintu hamwe n'amashanyarazi akoreshejwe. Ubundi ni ingaruka za electro-optical za kabiri, zizwi kandi nka Kerr effect, aho impinduka mu gipimo cya refractive y'ikintu ingana na kare y'amashanyarazi. Modulators nyinshi za electro-optical zishingiye ku ngaruka za Pokels. Dukoresheje modulators za electro-optical, dushobora guhindura phase y'urumuri rw'impanuka, kandi dushingiye ku ihinduka ry'igice, binyuze mu ihinduka runaka, dushobora kandi guhindura ubukana cyangwa polarization y'urumuri.

Hari imiterere itandukanye ya kera, nk'uko bigaragara ku Ishusho ya 2. (a), (b) na (c) byose ni imiterere imwe ya modulator ifite imiterere yoroshye, ariko ubugari bw'umurongo w'imashini ya optique ikorwa bugengwa n'umurongo wa electro-optical. Niba hakenewe imashini ya optique ifite frequency yo gusubiramo cyane, hakenewe modulator ebyiri cyangwa nyinshi muri cascade, nk'uko bigaragara ku Ishusho ya 2 (d) (e). Ubwoko bwa nyuma bw'imiterere butanga optique frequency comb bwitwa electro-optical resonator, ari yo modulator ya electro-optical ishyirwa muri resonator, cyangwa resonator ubwayo ishobora gutanga ingaruka za electro-optical, nk'uko bigaragara ku Ishusho ya 3.

ISHUSHO YA 2 Ibikoresho byinshi byo kugerageza gukora imashini zikoresha frequency optique zishingiye kumodulators za electro-optique

ISHUSHO YA 3 Imiterere y'imiyoboro myinshi y'amashanyarazi n'amatara
03 Ibiranga uburyo Electro-optic modulation optical frequency comb

Akamaro ka mbere: ubushobozi bwo gutunganya ibintu

Kubera ko isoko y'urumuri ari laser ifite spectrum wide-spectrum, kandi modulator ya electro-optical ifite bandwidth runaka y'imikorere, electro-optical modulation optical frequency comb nayo ishobora guhindurwa. Uretse frequency ishobora guhindurwa, kubera ko modulator ishobora guhindurwa, frequency isubiramo y'imashini isohoka nayo ishobora guhindurwa. Iki ni akarusho ko optical frequency comb zikozwe na mode-locked lasers na micro-resonators zidafite.

Akamaro ka kabiri: inshuro zo gusubiramo

Igipimo cyo gusubiramo ntabwo gihinduka gusa, ahubwo gishobora no kugerwaho hatabayeho guhindura ibikoresho by'igerageza. Ubugari bw'umurongo w'urukuta rw'umuvuduko w'amashanyarazi bungana hafi n'umuvuduko w'umuvuduko w'amashanyarazi, umuvuduko rusange w'umuvuduko w'amashanyarazi ni 40GHz, kandi umuvuduko w'umuvuduko w'amashanyarazi usubiramo ushobora kurenza umuvuduko w'umuvuduko w'amashanyarazi ukorwa n'ubundi buryo bwose uretse micro resonator (ishobora kugera kuri 100GHz).

Akamaro ka 3: gushushanya imiterere ya spectral

Ugereranyije n'imashini ikora mu buryo butandukanye, imiterere ya disiki y'imashini ikora mu buryo bwa electro-optic igenwa n'ibipimo bitandukanye by'ubwisanzure, nko gukoresha signal ya radio frequency, bias voltage, incident polarization, nibindi, bishobora gukoreshwa mu kugenzura ubukana bw'imashini zitandukanye kugira ngo bigere ku ntego yo gushyiraho spectral shaping.

04 Gukoresha igikoresho cy'amashanyarazi gikoresha ikoranabuhanga rya frequency optique

Mu ikoreshwa ry’imashini ikoresha amashanyarazi ya optique modulator, ishobora kugabanywamo spectra imwe n’ebyiri. Intera iri hagati y’umurongo n’umwe ni nto cyane, bityo uburyo bwo gukora neza bushobora kugerwaho. Muri icyo gihe, ugereranije n’imashini ikoresha amashanyarazi ya optique ikorwa na laser ifunguye, igikoresho cya electro-optique modulator optique modulator ni gito kandi gishobora guhindurwa neza. Spektrometeri ya double comb ikorwa no kubangamirana kw’imashini ebyiri zihuza hamwe zifite frequencies zitandukanye gato zo gusubiramo, kandi itandukaniro riri hagati y’inshuro zo gusubiramo ni intera iri hagati y’umurongo n’umwe ya spectrum nshya ya interference comb. Ikoranabuhanga rya optique frequency comb rishobora gukoreshwa mu gufata amashusho, gupima ubunini, gupima ibyuma, gushushanya spectrum ya waveform, photonics ya radio frequency, itumanaho rya kure, optique stealth n’ibindi.

ISHUSHO YA 4 Imiterere y'ikoreshwa ry'urushinge rw'amajwi: Gufata urugero rw'urugero rw'urushinge rw'amasasu yihuta cyane
