Ukuqonda okubanzi kweemodyuli ze-electro-optic
Imodyuli ye-Electro-optic (EOM) ngumguquli we-electro-optic osebenzisa iimpawu zombane ukulawula iimpawu ze-optical, ngokukodwa ezisetyenziswa kwinkqubo yokuguqulwa kwesignali ye-optical kwintsimi ye-telecommunications technology.
Oku kulandelayo yintshayelelo eneenkcukacha kwimodyuli ye-electro-optic:
1. Umgaqo osisiseko weimodyuli ye-electro-opticisekelwe kwimpembelelo ye-electro-optic, oko kukuthi, isalathisi esihlaziyiweyo sezinto ezithile siya kutshintsha phantsi kwesenzo sentsimi yombane esetyenzisiweyo. Njengoko amaza okukhanya edlula kwezi kristale, iimpawu zokusasaza zitshintsha kunye nentsimi yombane. Ukusebenzisa lo mgaqo, isigaba, i-amplitude okanye i-polarization state yeukubonaisignali inokulawulwa ngokutshintsha indawo yombane esetyenzisiweyo.
2. Ubume kunye nokubunjwa Iimodyuli ze-Electro-optical ngokubanzi ziqulunqwe ngeendlela ze-optical, i-amplifiers, izihlungi kunye nabaguquleli be-photoelectric. Ukongeza, ibandakanya amacandelo aphambili afana nabaqhubi besantya esiphezulu, iifibers optical kunye neekristale zepiezoelectric. Ukwakhiwa kwemodyuli ye-electro-optic modulator inokwahluka ngokwendlela yayo yokumodareyitha kunye neemfuno zesicelo, kodwa ngokuqhelekileyo ibandakanya iinxalenye ezimbini: imodyuli ye-electro-optic inverter kunye nemodyuli ye-photoelectric modulation.
3. Imowudi yokumodareyitha Imodyuli ye-Electro-optic ineendlela ezimbini eziphambili zokumodareyitha:ukumodareyitha kwesigabakunye nokumodareyitha kokuqina. Isigaba sokumodareyitha: Isigaba somthwali sitshintsha njengoko umqondiso olungisiweyo utshintsha. Kwimodyuli yePockels electro-optic, ukukhanya okuhamba rhoqo kudlula kwikristale ye-piezoelectric, kwaye xa kusetyenziswa i-voltage emodareyithiweyo, intsimi yombane iveliswa kwikristale ye-piezoelectric, ebangela ukuba isalathiso saso sitshintshe, ngaloo ndlela sitshintsha isigaba sokukhanya. .Ukumodareyitha kokuqina: Ukuqina (ukukhanya kokukhanya) kwenkampani ye-optical carrier iyatshintsha njengoko umqondiso oguquliweyo utshintsha. Ukumodareyitha okunzulu kudla ngokufezekiswa kusetyenziswa imodyuli yokuqina ye-Mach-Zehnder, elingana kumgangatho we-Mach-Zehnder interferometer. Emva kokuba imiqadi emibini imodareyithwe yingalo yokutshintsha kwesigaba esinokuqina okwahlukileyo, ekugqibeleni iyaphazamiseka ukuze ifumane ubungakanani besignali ye-optical intensity modulated.
4. Imimandla yesicelo Iimodyuli ze-electro-optical modulators zinoluhlu olubanzi lwezicelo kwiinkalo ezininzi, kubandakanywa kodwa kungaphelelanga apho: unxibelelwano lwe-optical: Kwiinkqubo zonxibelelwano ze-optical high-speed, i-electro-optical modulators isetyenziselwa ukuguqula iimpawu ze-elektroniki kwiimpawu ze-optical. ukufezekisa ukufakwa kwekhowudi kunye nokuhanjiswa kwedatha. Ngokumodareyitha ubunzulu okanye isigaba somqondiso we-optical, imisebenzi yokutshintsha ukukhanya, ukulawula izinga lokumodareyitha kunye nokuguqulwa kwesiginali kunokufezekiswa. I-Spectroscopy: Iimodyuli ze-electro-optical zingasetyenziswa njengamacandelo e-optical spectrum analyzers ukuhlalutya okubonakalayo kunye nokulinganisa. Umlinganiselo wobugcisa: iimodyuli ze-electro-optical nazo zidlala indima ebalulekileyo kwiinkqubo ze-radar, ukuxilongwa kwezonyango kunye nezinye iinkalo. Ngokomzekelo, kwiinkqubo ze-radar, ingasetyenziselwa ukumodareyitha komqondiso kunye nokunciphisa; Ekuxilongweni kwezonyango, ingasetyenziselwa umfanekiso we-optical kunye nonyango. Izixhobo ezitsha zombane wokufota: iimodyuli ze-electro-optical zinokusetyenziswa ukwenza izixhobo ezitsha zombane wefoto, ezinje ngokutshintsha kwe-electro-optical, i-isolator zamehlo, njl.
5. Izinto eziluncedo kunye nokungonakali Imodyuli ye-Electro-optic ineenzuzo ezininzi, ezifana nokuthembeka okuphezulu, ukusetyenziswa kwamandla aphantsi, ukufakwa lula, ubungakanani obuncinci kunye nokunye. Kwangaxeshanye, nayo ineempawu ezintle zombane kunye nobuchule bokuchasana nokuphazamiseka, obunokusetyenziselwa ukuhanjiswa kwebroadband kunye neentlobo ngeentlobo zeemfuno zokwenziwa komqondiso. Nangona kunjalo, imodyuli ye-electro-optic nayo ineziphene, ezifana nokulibaziseka kokuhanjiswa komqondiso, kulula ukuphazanyiswa ngamaza ombane angaphandle. Ngoko ke, xa usebenzisa i-electro-optic modulator, kuyimfuneko ukukhetha imveliso efanelekileyo ngokweemfuno zangempela zesicelo ukufezekisa umphumo omuhle wokumodareyitha kunye nokusebenza. Isishwankathelo, i-electro-optic modulator iyisiguquli esibalulekileyo se-electro-optic, enethuba elibanzi lesicelo kwiinkalo ezininzi ezifana nokunxibelelana kwe-optical, i-spectroscopy kunye nokulinganisa kobugcisa.
Ngenkqubela phambili eqhubekayo yesayensi kunye netekhnoloji kunye nemfuno eyandayo yezixhobo zokukhanya ezisebenza kakhulu, iimodyuli ze-electro-optical ziya kuphuhliswa ngokubanzi kwaye zisetyenziswe.
