Ukuqonda okuphelele kwama-electro-optic modulators
I-electro-optic modulator (Xothi) Isiguquli se-electro-optic esisebenzisa amasiginali kagesi okulawula amasiginali abonakalayo, ikakhulukazi asetshenziswa inqubo yokuguqula yesiginali ye-optical emkhakheni wobuchwepheshe bezokuxhumana.
Lokhu okulandelayo ukwethulwa okuningiliziwe ku-Electro-Optic Modulator:
1. Isisekelo esiyisisekelo seI-Electro-Optic ModulatorKususelwa emphumeleni we-electro-optic, okungukuthi, inkomba eyedlulayo yezinto ezithile izoshintsha ngaphansi kwesenzo sensimu kagesi esetshenzisiwe. Njengoba amagagasi akhanyayo adlula kulezi zinhlamvu, izici zokusakazeka zishintsha nensimu kagesi. Usebenzisa lesi simiso, isigaba, amplitude noma isimo se-polarization ye-phathelene nokubonaIsiginali ingalawulwa ngokushintsha insimu kagesi esetshenzisiwe.
2. Ukwakheka kanye nokwakheka kwe-electro-optical modulators ngokuvamile kuhlanganiswa izindlela zokubona, ama-amplifier, izihlungi kanye nabaguquli bezithombe zokuguqula. Ngaphezu kwalokho, kufaka phakathi izingxenye ezibalulekile ezifana nabashayeli abasheshe, imicu ye-Optical kanye namakristalu ePiezoelectric. Ukwakheka kwe-electro-optic modulator kungahluka ngokuya ngemodi yayo yokushintshanisa kanye nezidingo zohlelo lokusebenza, kepha kuvame ukufaka izingxenye ezimbili: imodyuli ye-electro-optic inverter kanye nemodyuli yokuguqulwa kwe-electrovectric.
3. Imodi yokushintshanisa imodi ye-electro-optic modulator inezindlela ezimbili zokushintshaUkushintshwa kwesigabanokuguquguquka okuphezulu. Ukushintshwa kwesigaba: Isigaba sesithwali sishintsha njengoshintsho lwesignali esilungisiwe. Ku-Pockels Electro-Optic Modulator, ukukhanya okufudumele kwe-carriers-frequency kudlula i-piezoelectric crystal, futhi lapho kufakwa i-voltage elungiselelwe, insimu kagesi yenziwa ku-piezoelectric crystal, okwenza i-Index ye-Piezoelectric, enze i-Index yakho yokuvula ishintsha, ngaleyo ndlela iguqule isigaba sokukhanya.Ukuguquguquka kokuqina: Ukuqina (ubukhulu obukhanyayo) be-optical Carrier ushintsho njengoshintsho lwesignali esilungisiwe. Ukuguquguquka kokuqina kuvame ukufinyelelwa kusetshenziswa i-mach-zehnder censity modulator, okulingana nomgomo we-mach-zehnder interferometer. Ngemuva kokuthi imishayo emibili ilungiswe yingalo eguqukayo yesigaba ngamandla ahlukile, ekugcineni aphazamisekile ukuthola isibonakaliso sokuqina esinqunyelwe.
I-4. Izindawo zohlelo lokusebenza i-Electro-Optical Modators zinezinhlobonhlobo zezicelo ezisezinkambulweni eziningi, kufaka phakathi: Izinhlelo zokuxhumana ze-Optical: E-Electro-optical systems zisetshenziselwa ukuguqula amasiginali we-elektroniki afinyelele ekufakweni kwedatha nokudlulisela. Ngokuguqula ubukhulu noma isigaba se-Optical Signal, imisebenzi yokushintshana okukhanyayo, ukulawulwa kwezinga lokushintshanisa kanye nokuguqulwa kwesiginali kungabonakala. Ama-spectroscopy: Ama-modulators a-electro-optical angasetshenziswa njengezakhi ze-Optical Spectrum Analyzers yokuhlaziywa kokubuka nokukalwa. Ukulinganiswa kobuchwepheshe: Ama-Modators e-Electro-Optical abuye adlale indima ebalulekile ezinhlelweni ze-radar, ukuxilongwa kwezokwelapha kanye nezinye izinkambu. Isibonelo, ezinhlelweni ze-radar, zingasetshenziselwa ukuguquguquka kwesiginali kanye nokumodation; Ekuhlolweni kwezokwelapha, ingasetshenziselwa ukucabanga nokwelashwa okubonakalayo. Amadivayisi amasha we-Photeelectric: Ama-moda actical modulators nawo angasetshenziswa ukukhiqiza amadivaysi amasha we-photoelectric, anjenge-Electro-Optical switch, ama-isolators oplical, njll.
I-5. Izinzuzo nokubi kwe-electro-optic modulator kunezinzuzo eziningi, njengokuthembela okuphezulu, ukusetshenziswa kwamandla okuphansi, ukufakwa okulula, usayizi omncane nokunye. Ngasikhathi sinye, futhi inezimpawu ezinhle zikagesi kanye nekhono lokulwa nokumelana, elingasetshenziselwa ukuhanjiswa kwe-Broadband kanye nezidingo ezahlukahlukene zokucubungula iziginali. Kodwa-ke, i-electro-optic modulator nayo inamaphutha, njengokubambezeleka kwesiginali, kulula ukuxhashazwa ngamagagasi angaphandle we-electromagnetic. Ngakho-ke, lapho usebenzisa i-electro-optic modulator, kuyadingeka ukuthi ukhethe umkhiqizo ofanele ngokuya ngohlelo lokusebenza langempela ludinga ukufeza umphumela omuhle wokushintshanisa nokusebenza. Ngamafuphi, i-electro-optic modulator iyinhlangano ebalulekile ye-electro-optic converter, enethemba lesicelo elibanzi emikhakheni eminingi efana nokuxhumana okubonakalayo, i-spectroscopy kanye nesilinganiso sobuchwepheshe.
Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe kanye nesidingo esandayo samadivayisi wokusebenza okuphezulu, ama-elektro-ama-modulators azothuthukiswa kabanzi futhi asetshenziswe.
