Ukuqonda okuphelele kwama-modulators e-electro-optic
I-Electro-optic modulator (I-EOM) iyisiguquli se-electro-optic esisebenzisa amasignali kagesi ukulawula amasignali optical, esisetshenziswa kakhulu enqubweni yokuguqulwa kwamasignali optical emkhakheni wezobuchwepheshe bezokuxhumana.
Okulandelayo isingeniso esinemininingwane se-electro-optic modulator:
1. Isimiso esiyisisekelo se-i-electro-optic modulatorkusekelwe kumphumela we-electro-optic, okungukuthi, inkomba yokukhanya kwezinye izinto izoshintsha ngaphansi kwesenzo sensimu kagesi esetshenzisiwe. Njengoba amagagasi okukhanya edlula kula makristalu, izici zokusabalala ziyashintsha nensimu kagesi. Ukusebenzisa lesi simiso, isimo sesigaba, ubukhulu noma ukwahlukana kwe-ukukhanyaisignali ingalawulwa ngokushintsha insimu kagesi esetshenzisiwe.
2. Isakhiwo nokwakheka Ama-modulators e-electro-optical ngokuvamile akhiwa izindlela zokukhanya, ama-amplifier, izihlungi kanye nabaguquli be-photoelectric. Ngaphezu kwalokho, ifaka izingxenye ezibalulekile ezifana nabashayeli besivinini esikhulu, imicu ye-optical kanye namakristalu e-piezoelectric. Isakhiwo se-modulator ye-electro-optic singahluka ngokuya ngemodi yayo yokuguquguquka kanye nezidingo zohlelo lokusebenza, kodwa ngokuvamile sifaka izingxenye ezimbili: i-module ye-electro-optic inverter kanye ne-module ye-photoelectric modulation.
3. Imodi yokushintshashintsha i-Electro-optic modulator inezindlela ezimbili eziyinhloko zokushintshashintsha:ukuguqulwa kwesigabakanye nokuguquguquka kwamandla. Ukuguquguquka kwesigaba: Isigaba sesithwali siyashintsha njengoba isignali eguquliwe ishintsha. Ku-modulator ye-electro-optic ye-Pockels, ukukhanya kwemvamisa yesithwali kudlula ngekristalu ye-piezoelectric, futhi lapho kusetshenziswa i-voltage eguquliwe, insimu kagesi ikhiqizwa kukristalu ye-piezoelectric, okubangela ukuthi inkomba yayo yokukhanya ishintshe, ngaleyo ndlela kushintshe isigaba sokukhanya.Ukuguqulwa kwamandla: Ukuqina (ukuqina kokukhanya) kwesithwali se-optical kuyashintsha njengoba isignali eguquliwe ishintsha. Ukuguquguquka kokuqina kuvame ukufezwa kusetshenziswa i-modulator ye-Mach-Zehnder intensity, elingana ngokomthetho ne-interferometer ye-Mach-Zehnder. Ngemva kokuba imisebe emibili iguquliwe yingalo eshintshayo yesigaba ngamandla ahlukene, ekugcineni iyaphazanyiswa ukuze kutholakale isignali ye-optical eguquliwe intensity.
4. Izindawo Zokusebenza Ama-modulators e-electro-optical anezinhlelo zokusebenza eziningi emikhakheni eminingi, okuhlanganisa kodwa kungagcini lapho: ukuxhumana kwe-optical: Ezinhlelweni zokuxhumana kwe-optical ezisheshayo, ama-modulators e-electro-optical asetshenziswa ukuguqula amasignali kagesi abe amasignali optical ukuze kufezwe ukufakwa kwekhodi kwedatha kanye nokudluliselwa kwayo. Ngokushintsha ubukhali noma isigaba sesignali yokukhanya, imisebenzi yokushintsha ukukhanya, ukulawula izinga lokuguquguquka kanye nokuguqulwa kwesignali ingafezeka. I-Spectroscopy: Ama-modulators e-electro-optical angasetshenziswa njengezingxenye zama-optical spectrum analyzers okuhlaziya nokulinganisa ama-spectral. Ukulinganisa kobuchwepheshe: ama-modulators e-electro-optical nawo adlala indima ebalulekile ezinhlelweni ze-radar, ekuxilongweni kwezokwelapha nakwezinye izinkambu. Isibonelo, ezinhlelweni ze-radar, ingasetshenziswa ekushintsheni kwesignali kanye nokususwa kwe-demodulation; Ekuxilongweni kwezokwelapha, ingasetshenziswa ekuthathweni kwezithombe ze-optical kanye nokwelashwa. Amadivayisi amasha e-photoelectric: ama-modulators e-electro-optical angasetshenziswa futhi ukukhiqiza amadivayisi amasha e-photoelectric, njengezishintshi ze-electro-optical, ama-isolators optical, njll.
5. Izinzuzo kanye nokungalungi I-Electro-optic modulator inezinzuzo eziningi, njengokuthembeka okuphezulu, ukusetshenziswa kwamandla aphansi, ukufakwa okulula, usayizi omncane njalonjalo. Ngesikhathi esifanayo, inezici ezinhle zikagesi kanye nekhono lokulwa nokuphazamiseka, okungasetshenziswa ekudlulisweni kwe-broadband kanye nezidingo ezahlukahlukene zokucubungula isignali. Kodwa-ke, i-electro-optic modulator nayo inezinkinga ezithile, njengokulibaziseka kokudluliselwa kwesignali, kulula ukuphazanyiswa amaza kagesi angaphandle. Ngakho-ke, uma usebenzisa i-electro-optic modulator, kubalulekile ukukhetha umkhiqizo ofanele ngokwezidingo zangempela zohlelo lokusebenza ukuze kufezwe umphumela omuhle wokuguqulwa kanye nokusebenza. Ngamafuphi, i-electro-optic modulator iyi-converter ebalulekile ye-electro-optic, enethuba elibanzi lokusetshenziswa emikhakheni eminingi njengokuxhumana kwe-optical, i-spectroscopy kanye nokulinganisa kobuchwepheshe.
Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe kanye nesidingo esikhulayo samadivayisi okukhanya asebenza kahle kakhulu, ama-modulators e-electro-optical azothuthukiswa futhi asetshenziswe kabanzi.
