Iiparameter eziphambili zeImodulator kaMach Zehnder
I-Mach Zehnder Modulator (i-MZM Modulator) yimodeli ephezulu kakhului-electro-optic intensity modulatoryaphuhliswa ngokusekelwe kumgaqo wokuphazamiseka kwamehlo. Iphantsi kwesebe elibalulekileyo leukuguquguquka kwe-electro-optickwinkqubo yetekhnoloji ye-optical modulation. Okwangoku, iimveliso eziphambili zilungiswa kusetyenziswa itekhnoloji ye-optical waveguide ye-lithium niobate (LiNbO3). Ngeenzuzo zayo ezintathu eziphambili zokusebenza kwe-ultra-low chirp, i-ultra-high extinction ratio, kunye ne-ultra large modulation bandwidth, iye yaba yimveliso ye-benchmark modulation eyaziwayo kwimimandla yonxibelelwano lwe-backbone fiber optic olude, unxibelelwano lwe-coherent optical, i-optical frequency comb generation, kunye neenkqubo ze-laser ezikhawulezayo.
1, iiparameter eziphambili:
1.1 Ubude bomda obusebenzayo: 1310nm/1550nm okwangoku lukhetho oluphambili kwicandelo lonxibelelwano
1.2 I-voltage yesiqingatha se-V π: Iimveliso zesikhokelo samaza zorhwebo zihlala zilawulwa ngaphakathi kwe-5V. Okukhona i-voltage yesiqingatha se-voltage iphantsi, kokukhona ixabiso lokuqhuba lesixhobo esifanelekileyo liphantsi.
1.3 I-bandwidth yokuguquguquka: Okwangoku, iimveliso zorhwebo zahlulwe kakhulu ngokwamanqanaba ahlukeneyo e-40G/80G/120GHz;
1.4 Umlinganiselo wokuphela: Umlinganiselo wokuphela kweemveliso ezisemgangathweni ophezulu unokufikelela ngaphezulu kwe-25dB, kunye nokusebenza okugqwesileyo kune-EAM
1.5 Ukulahleka kokufakwa: Ixabiso eliqhelekileyo likwi-3 ~ 4.5dB;
1.6 I-Chirp Coefficient: Iimveliso ezisebenza kakuhle kakhulu zinokufikelela phantse kwi-zero chirp, nto leyo eyinzuzo yazo ephambili kwiimeko zokusasazwa komgama omde.
2. Udidi lwemveliso:
2.1 Ngemo yokuqhuba: ukuguquguquka kwengalo enye, ukuguquguquka kokutyhala nokutsala kwengalo ezimbini (okuqhelekileyo kwicandelo lonxibelelwano, kunye nomgca ongcono);
2.2 Ngomsebenzi: Amandla aqhelekileyoI-MZM Modulator, i-IQ edibeneyo ye-MZM Modulator (enikezelwe kunxibelelwano oluhambelanayo, edityaniswe yi-orthogonal dual MZM Modulator.
2.3 Iimveliso zorhwebo zisekelwe ikakhulu kwiindlela ezidityanisiweyo zokulawula amaza, ukusebenza okulinganiselayo kunye nokuzinza kwemveliso ngobuninzi.
3. Iimeko zesicelo:
Ukugubungela inethiwekhi yomqolo i-400G/800G/1.6T iimodyuli ze-optical ezikude, i-coherent optical radar/fiber sensing, i-ultrafast laser mode locking/optical frequency comb preparation, ulawulo lwe-quantum communication phase kunye nezinye iindawo.
4. Uphuhliso lwendlela:
Ukuqhubela phambili ekuncitshisweni kwe-thin film lithium niobate MZM modulator kunye nokuveliswa ngobuninzi kwee-silicon-based integrated MZM modulators, ukufikelela ekunciphiseni iindleko kunye nokuphucula ukusebenza kakuhle, kunye nokwandisa iimeko zokusetyenziswa ngakumbi.
