Indima yefilimu emdaka ye-lithium ye-liobate kwi-electro-optic modulator

Indima yefilimu emdaka ye-lithium ye-Niobate ngaphakathiImodyuli ye-electro-optic
Ukususela ekuqaleni komzi-mveliso ukuya kuthiwa, amandla onxibelelwano ngenye i-fiber anyuke ngezigidi zamaxesha, kwaye inani elincinci lophando olusika ligqithile kumashumi izigidi zamaxesha. I-Lithium Niobate yadlala indima enkulu embindini weshishini lethu. Kwiintsuku zokuqala zonxibelelwano lwefayili ephepheni, imodyuli yophawu lokukhanya lwalulungiswa ngokuthe ngqo kwii-laser. Le ndlela yolawulo lwemodyuli yamkelekile kwi-bandwidth ephantsi okanye izicelo zomgama ezimfutshane. Ukufumana imondo emfutshane yesantya kunye nokusetyenziswa kumgama omde, kuya kubakho i-bandwidth eyoneleyo kunye nejelo lokuhambisa libiza kakhulu ukuhlangabezana nezicelo ezinde.
Embindini wonxibelelwano lwe-fical ficacacal, indlela yokusebenza yomqondiso ihamba ngokukhawuleza kwaye ihamba ngokukhawuleza ukuhlangabezana nokwanda komthamo wonxibelelwano, kwaye imodyuli yemodyuli yokuthengisa iyodwa iqala ukwahlukana nenethiwekhi yomgama omfutshane kunye nenethiwekhi yomgama omde. Imodyuli ethe ngqo kwixabiso eliphantsi isetyenziswa kwinethiwekhi yomgama omfutshane, kunye ne-MODRO-Optic Podulator "isetyenziswa kumgama omde we-trunk, ohlukaniswe ne-trink the thernnet, eyahluliweyo kwi-laser.
Imodyuli ye-electro-optic isebenzisa ulwakhiwo lwezinto eziphathwayo kwimodyuli, ukukhanya yi-elektromagnetic wave, i-elektromagnetic wave, i-Electromagnetic Waves elawula rhoqo, iSigaba kunye nokuPolarial. Sisoloko sikhankanya igama, ebizwa ngokuba yi-pherings, ukukhanya kunye nemiphetho emnyama, iqaqambile yindawo apho kuya kuphuculwa khona i-electromagneti, emnyama yindawo ekuphazamiseka kuyo i-electromagnetic ibangela amandla. Impatho-nxaxheba ye-Mahzener luhlobo lwe-idrommeter ngesakhiwo esikhethekileyo, esiyimpembelelo yokulawulwa okulawulwa ngokulawula inqanaba le-beam efanayo emva kokuqhekeza i-beam. Ngamanye amagama, isiphumo sokuphazamiseka sinokulawulwa ngokulawula iSigaba sokuphazamiseka.
I-Lithium i-Niobate le nto isetyenziswa kunxibelelwano lwe-fiphal ficacacal, oko kukuthi, inokusebenzisa inqanaba le-voltage (i-SIRTAL) ukulawula isigaba sokukhanya, ukuba lube lulwalamano phakathi kwemodyuli ye-electro-optical kunye ne-lithium. I-modulator yethu ibizwa ngokuba yimodyuli ye-electro-optic, ekufuneka iqwalasele zombini intembeko yomqondiso wombane kunye nomgangatho wemodyuli yophawu lokukhanya. Umthamo wombane weMiqondiso ye-Indim phosphide kunye ne-selicon Photonics ilunge ngakumbi kunelo ye-lithium, kunye nomthamo wophawu lwe-hithical sinokusetyenziswa kancinci, nto leyo eyenza indlela entsha yokuthatha ithuba lentengiso.
Ukongeza kwiipropathi zabo ezintle, i-Indim phosphide kunye ne-Silicon Photonics ze-FILICON zinezibonelelo zokulinganisa kunye nokudityaniswa kwe-lithium wiobete ayinayo. I-Indim phosphide incinci kune-lithium kwaye inesidanga esiphezulu sokudityaniswa, kwaye iifoto ze-silicon zincinci kune-Indion phosfide kwaye inesidanga esiphezulu. Intloko ye-lithium ye-Niobate njengeI-MUDLALOTORiphindwe kabini njenge-Indim Fosphide, kwaye inokuba ngumnxibelelanisi kuphela kwaye ayinakho ukudibanisa neminye imisebenzi.
Okwangoku, i-modulilical ye-electro-optical ingene kwixesha lexabiso lezigidi ezili-100 lebhiliyoni, (i-128g lili-128 bhiliyoni), kwaye i-lithium ye-liobate iphinde yakhokelela kweli xesha kwintengiso yamawaka angama-250 yebhiliyoni. Kwi-lithium ye-lithium ukuba iphinde iphinde le ntengiso, iyimfuneko ukuhlalutya into i-Indiel phosphide kunye neefoto ze-silicon zinayo, kodwa i-lithium ye-Niobate ayinayo. Olo lubane lombane, indibaniselwano ephezulu, ubumbili.
Utshintsho lwe-lithium i-zuobate lilele kwii-angles ezintathu, i-engile yokuqala yindlela yokuphucula amandla ombane, i-engile yesibini yindlela yokuphucula ukudityaniswa, kwaye i-engile yesithathu yindlela yokulinganisa. Isisombululo kwezi nye ze-engles ezintathu zobugcisa zifuna isenzo esinye, oko kukuthi, ukuya kwifilimu ecekeceke i-liobete yezinto ezibonakalayo, phucula ubungakanani bombane, phucula ubume bombane, uphucule impumelelo yemozulu yombane. Ukuphucula amandla ombane. Le filimu inokuthi iqhotyoshelwe kwi-selicon wafer, yokufezekisa ukudityaniswa okuxutywayo, i-lithium piobate njengomdibaniso we-selicon phot, i-selicon phosetion icacile, ukuphucula ukudityaniswa kwendalo.
Kwixesha elizayo, imodyuli ye-electro-optical sele iza kungena kwixesha lama-200 eebhili-bhiliyoni ye-2000 ye-Indim phosphide kwaye ifilimu ye-liobate iphucula ifilimu yale mibandela, kwaye ishishini igxile kule "filimu I-Lithium Niobate ", oko kukuthi, ifilimu emdakaI-Lithium Niobate Modulator. Le yindima yefilimu yefilim i-lithium ye-liobete kwicandelo le-modralical ye-electro.
