Ukuqonda okubanzi kwee-modulators ze-electro-optic
Imodulator ye-Electro-optic (I-EOM) sisiguquli se-electro-optic esisebenzisa imiqondiso yombane ukulawula imiqondiso ye-optical, esetyenziswa kakhulu kwinkqubo yokuguqula imiqondiso ye-optical kwicandelo lobuchwepheshe bonxibelelwano.
Oku kulandelayo yintshayelelo eneenkcukacha kwi-electro-optic modulator:
1. Umgaqo osisiseko wei-electro-optic modulatorisekelwe kwisiphumo se-electro-optic, oko kukuthi, isalathisi sokukhanyela kwezinye izinto siya kutshintsha phantsi kwesenzo sentsimi yombane esetyenzisiweyo. Njengoko amaza okukhanya edlula kwezi kristale, iimpawu zokusasazeka ziyatshintsha kunye nentsimi yombane. Ukusebenzisa lo mgaqo, imeko yesigaba, ubukhulu okanye i-polarization yei-opticalisignali ingalawulwa ngokutshintsha intsimi yombane esetyenzisiweyo.
2. Ulwakhiwo kunye nokwakheka Iimodulators ze-electro-optical zihlala zenziwe ngeendlela ze-optical, ii-amplifier, izihluzi kunye nee-photoelectric converters. Ukongeza, ibandakanya izinto ezibalulekileyo ezifana nee-high-speed drivers, ii-optical fibers kunye neekristale ze-piezoelectric. Ulwakhiwo lwe-electro-optic modulator lunokwahluka ngokwemo yayo ye-modulation kunye neemfuno zesicelo, kodwa luhlala luquka amacandelo amabini: i-electro-optic inverter module kunye ne-photoelectric modulation module.
3. Imo yokuguqula imodulator ye-Electro-optic ineendlela ezimbini eziphambili zokuguqula:uhlengahlengiso lwesigabakunye nokuguqulwa kobunzulu. Ukuguqulwa kwesigaba: Isigaba somthwali siyatshintsha njengoko isignali eguquliweyo itshintsha. Kwi-Pockels electro-optic modulator, ukukhanya kwe-carrier-frequency kudlula kwi-crystal ye-piezoelectric, kwaye xa kusetyenziswa i-voltage eguquliweyo, intsimi yombane iveliswa kwi-crystal ye-piezoelectric, nto leyo ebangela ukuba i-refractive index yayo itshintshe, ngaloo ndlela itshintshe isigaba sokukhanya.Ukuguqulwa kwamandla: Ubunzulu (ubunzulu bokukhanya) bomthwali we-optical buyatshintsha njengoko isignali eguquliweyo itshintsha. Ukuguquguquka kobunzulu kudla ngokuphunyezwa kusetyenziswa i-Mach-Zehnder intensity modulator, elingana ngokomgaqo ne-Mach-Zehnder interferometer. Emva kokuba imisebe emibini iguquliwe yingalo yokutshintsha kwesigaba ngamandla ahlukeneyo, ekugqibeleni iyaphazanyiswa ukuze kufunyanwe isignali yokukhanya eguquliweyo.
4. Iindawo zokusetyenziswa Iimodulators ze-electro-optical zineentlobo ngeentlobo zezicelo kwiindawo ezahlukeneyo, kuquka kodwa kungaphelelanga apho: unxibelelwano lwe-optical: Kwiinkqubo zonxibelelwano lwe-optical olukhawulezayo, iimodulators ze-electro-optical zisetyenziselwa ukuguqula iisignali ze-elektroniki zibe ziisignali ze-optical ukuze kufezekiswe ikhowudi yedatha kunye nokudluliselwa kwayo. Ngokuguqula ubunzulu okanye isigaba sesignali ye-optical, imisebenzi yokutshintsha ukukhanya, ulawulo lwesantya se-modulation kunye nokuguqulwa kwesignali inokufezekiswa. I-Spectroscopy: Iimodulators ze-electro-optical zingasetyenziswa njengezixhobo ze-optical spectrum analyzers zohlalutyo lwe-spectral kunye nokulinganisa. Umlinganiselo wobugcisa: iimodulators ze-electro-optical nazo zidlala indima ebalulekileyo kwiinkqubo ze-radar, ukuxilongwa kwezonyango kunye nezinye iindawo. Umzekelo, kwiinkqubo ze-radar, ingasetyenziselwa ukuguquguquka kwesignali kunye nokususwa kwe-demodulation; Ekuxilongweni kwezonyango, ingasetyenziselwa ukuboniswa kwe-optical kunye nonyango. Izixhobo ezintsha ze-photoelectric: iimodulators ze-electro-optical zingasetyenziselwa ukuvelisa izixhobo ezintsha ze-photoelectric, ezifana nokutshintsha kwe-electro-optical, ii-optical isolators, njl.
5. Iingenelo kunye nokungalungi I-electro-optic modulator ineengenelo ezininzi, ezinje ngokuthembeka okuphezulu, ukusetyenziswa kwamandla aphantsi, ukufakwa lula, ubungakanani obuncinci njalo njalo. Kwangaxeshanye, ikwanazo neempawu ezilungileyo zombane kunye nokukwazi ukulwa nokuphazamiseka, okunokusetyenziselwa ukusasazwa kwe-broadband kunye neemfuno ezahlukeneyo zokucubungula isignali. Nangona kunjalo, i-electro-optic modulator ikwanazo nezinye iziphene, ezinje ngokulibaziseka kokusasazwa kwesignali, kulula ukuphazanyiswa ngamaza e-electromagnetic angaphandle. Ke ngoko, xa usebenzisa i-electro-optic modulator, kuyimfuneko ukukhetha imveliso efanelekileyo ngokweemfuno zokwenyani zesicelo ukuze kufezekiswe isiphumo esihle sokumodareyitha kunye nokusebenza. Ngamafutshane, i-electro-optic modulator sisiguquli esibalulekileyo se-electro-optic, esinethuba elibanzi lokusetyenziswa kwiinkalo ezininzi ezifana nonxibelelwano lwe-optical, i-spectroscopy kunye nokulinganisa kobugcisa.
Ngenxa yenkqubela phambili eqhubekayo yesayensi netekhnoloji kunye nemfuno ekhulayo yezixhobo ze-optical ezisebenza kakuhle, ii-electro-optical modulators ziya kuphuhliswa kwaye zisetyenziswe ngokubanzi.
