Ukuqonda okuphelele kwama-electro-optic modulators
I-Electro-optic modulator (I-EOM) isiguquli se-electro-optic esisebenzisa amasignali kagesi ukulawula amasignali okubona, ikakhulukazi asetshenziswa kunqubo yokuguqula isignali ye-optical emkhakheni wobuchwepheshe bezokuxhumana.
Okulandelayo yisingeniso esinemininingwane yemoduli ye-electro-optic:
1. Isimiso esiyisisekelo se-i-electro-optic moduleisekelwe kumphumela we-electro-optic, okungukuthi, inkomba ye-refractive yezinye izinto izoshintsha ngaphansi kwesenzo senkambu kagesi esetshenzisiwe. Njengoba amaza okukhanya edlula kulawa makristalu, izici zokusakaza ziyashintsha nensimu kagesi. Ukusebenzisa lesi simiso, isigaba, i-amplitude noma isimo se-polarization ye-opticalisignali ingalawulwa ngokushintsha inkambu kagesi esetshenzisiwe.
2. Isakhiwo nokubunjwa Amamojula we-Electro-optical ngokuvamile akhiwa izindlela zokubona, ama-amplifiers, izihlungi kanye neziguquli zikagesi wezithombe. Ngaphezu kwalokho, kuhlanganisa izingxenye ezibalulekile ezifana nabashayeli bejubane eliphezulu, imicu ye-optical kanye namakristalu e-piezoelectric. Isakhiwo se-electro-optic modulator singahluka ngokuya ngemodi yayo yokuguquguquka kanye nezidingo zohlelo lokusebenza, kodwa ngokuvamile kuhlanganisa izingxenye ezimbili: imodyuli ye-electro-optic inverter kanye nemodyuli ye-photoelectric modulation.
3. Imodi yokuguquguquka Imoduli ye-Electro-optic inezinhlobo ezimbili eziyinhloko zokumodulisa:ukuguqulwa kwesigabakanye nokushintshashintsha kokuqina. Ukushintshwa kwesigaba: Isigaba sesithwali siyashintsha njengoba isignali eshintshiwe ishintsha. Kumoduli ye-Pockels electro-optic, ukukhanya kwe-carrier-frequency kudlula ikristalu ye-piezoelectric, futhi lapho kusetshenziswa i-voltage eshintshiwe, inkambu kagesi ikhiqizwa kukristalu ye-piezoelectric, okubangela ukuthi inkomba yayo ekhanyayo ishintshe, ngaleyo ndlela iguqule isigaba sokukhanya. .Ukushintshashintsha kokuqina: Ukuqina (ukuqina kokukhanya) kwesiphathi senethiwekhi siyashintsha njengoba isignali eshintshiwe ishintsha. Ukuguquguquka kokuqina ngokuvamile kufinyelelwa kusetshenziswa imoduli yokuqina ye-Mach-Zehnder, elingana ngokomgomo ne-interferometer ye-Mach-Zehnder. Ngemva kokuba imishayo emibili ishintshiwe ingalo eshintshayo yesigaba enokuqina okuhlukile, ekugcineni iyaphazanyiswa ukuze ithole isignali yokubona eshintshashintshayo.
4. Izindawo zokufaka izicelo Amamojula we-electro-optical anezinhlobonhlobo zezinhlelo zokusebenza emikhakheni eminingana, okuhlanganisa kodwa okungakhawulelwe kulokhu: Ukuxhumana okubonakalayo: Ezinhlelweni zokuxhumana ezisebenza ngesivinini esikhulu, amamojula kagesi asetshenziswa ukuguqula amasiginali kagesi abe amasignali abonakalayo. ukuze kuzuzwe ukubhala ngekhodi nokudlulisa idatha. Ngokulungisa ukuqina noma isigaba sesiginali ye-optical, imisebenzi yokushintsha ukukhanya, ukulawulwa kwezinga lokushintshashintsha nokushintshashintsha kwesignali kungenziwa. I-Spectroscopy: Ama-modulators e-Electro-optical angasetshenziswa njengezingxenye ze-optical spectrum analyzer ukuze kuhlaziywe i-spectral kanye nesilinganiso. Ukulinganisa kobuchwepheshe: ama-modulators e-electro-optical nawo adlala indima ebalulekile ezinhlelweni ze-radar, ukuxilonga kwezokwelapha neminye imikhakha. Isibonelo, ezinhlelweni ze-radar, ingasetshenziselwa ukuguquguquka kwesignali nokudilizwa; Ekuxilongweni kwezokwelapha, ingasetshenziselwa i-optical imaging kanye nokwelapha. Imishini emisha yezithombe zikagesi: ama-modulators e-electro-optical angasetshenziswa ukwenza amadivaysi amasha kagesi wezithombe, njengamaswishi e-electro-optical, ama-optical isolator, njll.
5. Izinzuzo kanye nokubi Imoduli ye-Electro-optic inezinzuzo eziningi, njengokuthembeka okuphezulu, ukusetshenziswa kwamandla okuphansi, ukufakwa okulula, usayizi omncane nokunye. Ngesikhathi esifanayo, futhi inezici ezinhle zikagesi kanye nekhono lokulwa nokuphazamiseka, elingasetshenziselwa ukuhanjiswa kwe-broadband kanye nezidingo ezihlukahlukene zokucubungula isignali. Kodwa-ke, imoduli ye-electro-optic nayo inokushiyeka okuthile, njengokulibaziseka kokudluliselwa kwesignali, kulula ukuphazanyiswa amaza kagesi angaphandle. Ngakho-ke, lapho usebenzisa i-electro-optic modulator, kuyadingeka ukukhetha umkhiqizo ofanele ngokuya ngezidingo zangempela zohlelo lokusebenza ukuze kuzuzwe umphumela omuhle wokuguquguquka nokusebenza. Kafushane, i-electro-optic modulator iyisiguquli esibalulekile se-electro-optic, esinethuba elibanzi lesicelo emikhakheni eminingi efana nokuxhumana optical, spectroscopy kanye nesilinganiso sobuchwepheshe.
Ngokuqhubeka okuqhubekayo kwesayensi nobuchwepheshe kanye nesidingo esikhulayo semishini yokubona esebenza kahle kakhulu, ama-modulators e-electro-optical azothuthukiswa futhi asetshenziswe kabanzi.
