Ukusetyenziswa kweteknoloji yeimodyuli ye-electro-optic
Imodyuli ye-Electro-optic (Imodyuli ye-EOM） yinto yokulawula umqondiso esebenzisa i-electro-optic effect ukulungelelanisa isibane sokukhanya. Umgaqo wayo wokusebenza uphunyezwa ngokubanzi nge-Pockels effect (i-Pockels effect, eyi-Pockels effect), ethatha inzuzo yento yokuba isalathisi se-refractive se-nonlinear optical materials sitshintsha phantsi kwesenzo semimandla yombane.
Isakhiwo esisisiseko se-electro-optic modulator ngokuqhelekileyo ibandakanya i-crystal (i-Pockels crystal) kunye ne-electro-optical effect, kunye nezinto eziqhelekileyo ziyi-lithium niobate (LiNbO₃). Umbane ofunekayo ukuze wenze utshintsho kwisigaba ubizwa ngokuba yiHalf-wave voltage. Kwiikristale zePockels, amakhulu okanye amawaka e-volts ayimfuneko ngokwesiqhelo, kungoko imfuno yeamplifiers ephezulu yombane. Isiphaluka esifanelekileyo se-elektroniki sinokutshintsha i-voltage ephezulu kwii-nanoseconds ezimbalwa, ukuvumela ukuba i-EOM isetyenziswe njengokutshintsha ngokukhawuleza optical; Ngenxa yobume be-capacitive ye-crystals ze-Pockels, aba baqhubi kufuneka banikeze inani elikhulu langoku (kwimeko yokutshintsha ngokukhawuleza okanye ukumodareyitha, i-capacitance kufuneka incitshiswe ukunciphisa ukulahleka kwamandla). Kwezinye iimeko, njengaxa kuphela i-amplitude encinci okanye ukumodareyitha kwesigaba kuyadingeka, kuphela i-voltage encinci efunekayo ukumodareyitha. Ezinye izixhobo zekristale ezingezizo ezisetyenziswa kwiimodyuli ze-electro-optical (Imodyuli ye-EOM) ziquka i-titanate ye-potassium (i-KTP), i-beta-barium borate (i-BBO, ifanelekile kumandla aphezulu aphezulu kunye / okanye i-switching frequencies ephezulu), i-lithium tantalate (i-LiTaO3), kunye ne-ammonium phosphate (NH4H2PO4, i-ADP, eneempawu ezithile ze-electro-optical).
Iimodyuli ze-Electro-optic (Imodyuli ye-EO） bonisa amandla okusebenza abalulekileyo kwiinkalo ezininzi zobugcisa:
1. Unxibelelwano lwefayibha yokukhanya: Kuthungelwano lwezonxibelelwano lwangoku, iimodyuli ze-electro-optical (Imodyuli ye-EO） zisetyenziselwa ukumodareyitha imiqondiso ye-optical, ukuqinisekisa ukuhanjiswa kwedatha okusebenzayo nokuthembekileyo kumgama omde. Ngokulawula ngokuchanekileyo isigaba okanye i-amplitude yokukhanya, ukuhanjiswa kolwazi olukhawulezayo kunye nomthamo omkhulu kunokufezekiswa.
2. I-spectroscopy echanekileyo: Imodyuli ye-electro-optical modulates umthombo wokukhanya kwi-spectrometer ukuphucula ukuchaneka komlinganiselo. Ngokumodareyitha ngokukhawuleza i-frequency okanye isigaba somqondiso we-optical, ukuhlalutya kunye nokuchongwa kwezinto eziyinkimbinkimbi zeekhemikhali kunokuxhaswa, kwaye isisombululo kunye nokuqonda komlinganiselo we-spectral kunokuphuculwa.
3. I-high-performance optical data processing: i-modulator ye-electro-optical kwi-computing optical kunye ne-data processing system, ngokusebenzisa i-real-time modulation ye-optical signals ukuphucula isantya sokucubungula idatha kunye nokuguquguquka. Ngophawu lokuphendula olukhawulezayo lwe-EOM, i-high-speed and low-latency optical data processing kunye nokuhanjiswa kunokufezekiswa.
4. I-teknoloji ye-Laser: I-modulator ye-electro-optic inokulawula isigaba kunye ne-amplitude ye-laser beam, ukubonelela ngenkxaso ye-imaging echanekileyo, i-laser processing kunye nezinye izicelo. Ngokumodareyitha ngokuchanekileyo iiparamitha ze-laser beam, ukusetyenzwa kwe-laser ephezulu kunokuphunyezwa.
