Kugwiritsa ntchito ukadaulo wa electro-optic modulator

Tekinoloje yogwiritsira ntchitoelectro-optic modulator

Electro-optic modulator.EOM module） ndi chinthu chowongolera ma siginecha chomwe chimagwiritsa ntchito mphamvu ya electro-optic kusinthira kuwala. Mfundo yake yogwira ntchito nthawi zambiri imatheka kudzera mu Pockels effect (Pockels effect, yomwe ndi Pockels effect), yomwe imatenga mwayi pazochitikazo kuti refractive index of nonlinear optical materials amasintha pansi pa machitidwe a magetsi.

Mapangidwe a electro-optic modulator nthawi zambiri amaphatikizapo kristalo (Pockels crystal) yokhala ndi electro-optical effect, ndipo zinthu zomwe zimagwiritsidwa ntchito ndi lithiamu niobate (LiNbO₃). Mpweya wofunikira kuti usinthe gawo umatchedwa Half-wave voltage. Kwa makhiristo a Pockels, mazana kapena masauzande a ma volts amafunikira nthawi zambiri, chifukwa chake pamafunika ma amplifiers apamwamba kwambiri. Dongosolo loyenera lamagetsi limatha kusintha ma voliyumu apamwamba kwambiri mu nanoseconds pang'ono, kulola EOM kugwiritsidwa ntchito ngati chosinthira chofulumira; Chifukwa cha capacitive chikhalidwe cha Pockels makhiristo, madalaivalawa ayenera kupereka kuchuluka kwa panopa (pa nkhani ya mofulumira kusintha kapena modulation, capacitance ayenera kuchepetsedwa kuchepetsa kutaya mphamvu). Nthawi zina, monga ngati matalikidwe ang'onoang'ono kapena kusinthasintha kwa gawo kumafunika, voteji yaing'ono yokha ndiyofunika kuti musinthe. Zida zina zosagwirizana ndi kristalo zomwe zimagwiritsidwa ntchito mu electro-optical modulators (EOM module) monga potaziyamu titanate (KTP), beta-barium borate (BBO, yoyenera mphamvu yapamwamba kwambiri ndi/kapena ma frequency apamwamba), lithiamu tantalate (LiTaO3), ndi ammonium phosphate (NH4H2PO4, ADP, yokhala ndi ma electro-optical properties).

Electro-optic modulators.EO modulator） kuwonetsa kuthekera kofunikira pamagawo angapo apamwamba kwambiri:

1. Kuyankhulana kwa fiber: M'malo ochezera amakono a telecommunication, ma electro-optical modulators.EO modulator） amagwiritsidwa ntchito kuwongolera ma siginecha owoneka bwino, kuwonetsetsa kuti ma data akuyenda bwino komanso odalirika pamaulendo ataliatali. Mwa kuwongolera bwino gawo kapena matalikidwe a kuwala, kufalitsa uthenga wothamanga kwambiri komanso wochuluka kwambiri kungathe kukwaniritsidwa.

2. Chiwonetsero cholondola kwambiri: Modulator ya electro-optical modulator imasintha gwero la kuwala mu spectrometer kuti muyese molondola. Mwa kusintha mofulumira mafupipafupi kapena gawo la chizindikiro cha kuwala, kusanthula ndi kuzindikira zigawo zikuluzikulu za mankhwala zimatha kuthandizidwa, ndipo kuthetsa ndi kukhudzidwa kwa kuyeza kwa spectral kungapitirire.

3. High-performance optical data processing: electro-optical modulator mu optical computing ndi data processing system, kupyolera mu kusintha kwa nthawi yeniyeni ya zizindikiro za kuwala kuti ziwongolere liwiro la kukonza deta ndi kusinthasintha. Ndi mawonekedwe oyankha mwachangu a EOM, kukonza ndi kutumiza kwa data kothamanga kwambiri komanso kocheperako kumatha kuchitika.

4. Ukadaulo wa laser: The electro-optic modulator imatha kuwongolera gawo ndi matalikidwe a mtengo wa laser, kupereka chithandizo cha kujambula kolondola, kukonza laser ndi ntchito zina. Ndi ndendende modulating magawo a laser mtengo, apamwamba laser processing chingapezeke.
