Ikusasa leama-electro optical modulators

Ama-modulators e-Electro optic adlala indima ebalulekile ezinhlelweni zesimanje ze-optoelectronic, adlala indima ebalulekile emikhakheni eminingi kusukela kwezokuxhumana kuye kukhompyutha ye-quantum ngokulawula izakhiwo zokukhanya. Leli phepha lixoxa ngesimo samanje, impumelelo yakamuva kanye nentuthuko yesikhathi esizayo yobuchwepheshe be-electro optic modulator

Umfanekiso 1: Ukuqhathaniswa kokusebenza kokuhlukileimoduli ye-opticalubuchwepheshe, okufaka ifilimu elincanyana i-lithium niobate (TFLN), i-III-V Electric absorption modulators (EAM), i-silicon-based kanye nama-polymer modulators mayelana nokulahlekelwa kokufaka, umkhawulokudonsa, ukusetshenziswa kwamandla, usayizi, namandla okukhiqiza.

I-silicon-based electro optic modulators yendabuko kanye nokulinganiselwa kwayo

Amamojula wokukhanya we-photoelectric asuselwa ku-silicon abe yisisekelo sezinhlelo zokuxhumana ezibonakalayo iminyaka eminingi. Ngokusekelwe kumphumela wokuhlakazeka kwe-plasma, amathuluzi anjalo enze inqubekelaphambili emangalisayo phakathi neminyaka engu-25 edlule, enyusa amazinga okudluliswa kwedatha ngama-oda amathathu obukhulu. Amamojula asekelwe ku-silicon anamuhla angakwazi ukufeza i-4-level pulse amplitude modulation (PAM4) efika ku-224 Gb/s, ngisho nangaphezu kuka-300 Gb/s nge-PAM8 modulation.

Kodwa-ke, ama-modulators asekelwe ku-silicon abhekana nokulinganiselwa okuyisisekelo okuvela ezintweni ezibonakalayo. Lapho ama-transceivers optical edinga amazinga e-baud angaphezu kuka-200+ Gbaud, umkhawulokudonsa walawa madivaysi kunzima ukuhlangabezana nesidingo. Lo mkhawulo usukela ezimpahleni zemvelo ze-silicon - ibhalansi yokugwema ukulahleka kokukhanya okwedlulele kuyilapho ukugcinwa kwe-conductivity eyanele kudala ukuhwebelana okungenakugwenywa.

Ubuchwepheshe bemodyuli abasafufusa kanye nezinto zokwakha

Imikhawulo yamamoduli endabuko asuselwa ku-silicon iqhube ucwaningo kwezinye izinto kanye nobuchwepheshe bokuhlanganisa. Ifilimu elizacile i-lithium niobate isiphenduke enye yezinkundla ezithembisayo kakhulu zesizukulwane esisha samamoduli.Ifilimu elincanyana i-lithium niobate electro-optic modulatorszuza izici ezinhle kakhulu zenqwaba ye-lithium niobate, okuhlanganisa: iwindi elisobala elibanzi, i-electro-optic coefficient enkulu (r33 = 31 pm/V) umugqa weseli umphumela we-Kerrs ungasebenza kububanzi obungamaza amaningi

Intuthuko yakamuva kubuchwepheshe befilimu obuncane be-lithium niobate ilethe imiphumela emangalisayo, okuhlanganisa imoduli esebenza ku-260 Gbaud enezilinganiso zedatha ze-1.96 Tb/s isiteshi ngasinye. Inkundla inezinzuzo ezihlukile ezifana ne-CMOS-compatible drive voltage kanye no-3-dB bandwidth we-100 GHz.

Isicelo sobuchwepheshe obusafufusa

Ukuthuthukiswa kwama-electro optic modulators kuhlobene eduze nezinhlelo zokusebenza ezivelayo emikhakheni eminingi. Emkhakheni wobuhlakani bokwenziwa nezikhungo zedatha,ama-modulators anesivinini esikhuluzibalulekile esizukulwaneni esilandelayo sokuxhuma, futhi izinhlelo zokusebenza zekhompuyutha ze-AI ziqhuba isidingo sama-transceivers axhumekeka we-800G ne-1.6T. Ubuchwepheshe be-modulator buphinde busetshenziswe: i-quantum information processing neuromorphic computing Frequency modulated continuous wave (FMCW) lidar microwave photon technology.

Ikakhulukazi, ifilimu elincanyana i-lithium niobate electro-optic modulators ikhombisa amandla ezinjinini zokucubungula zekhompyutha, ehlinzeka ngokushintshashintsha kwamandla aphansi okusheshayo okusheshisa ukufundwa komshini kanye nezicelo zobuhlakani bokwenziwa. Ama-modulators anjalo angasebenza futhi emazingeni okushisa aphansi futhi afanele ukuxhumana kwe-quantum-classical emigqeni ye-superconducting.

Ukuthuthukiswa kwamamodulators e-electro optic esizukulwaneni esilandelayo kubhekene nezinselelo ezinkulu ezimbalwa: Izindleko zokukhiqiza kanye nesikali: amamodulators e-lithium niobate efilimu elincanyana okwamanje alinganiselwe ekukhiqizeni i-wafer engu-150 mm, okuholela ezindlekweni eziphezulu. Imboni idinga ukwandisa usayizi we-wafer ngenkathi igcina ukufana kwefilimu kanye nekhwalithi. Ukudidiyelwa kanye nokuklama ngokubambisana: Ukuthuthukiswa okuyimpumelelo kweama-modulators asebenza kahle kakhuluidinga amakhono aphelele okuklama okuhlangene, okubandakanya ukusebenzisana kwama-optoelectronics nabaklami be-chip kagesi, abahlinzeki be-EDA, imithombo, nochwepheshe bokupakisha. Ubunkimbinkimbi bokukhiqiza: Nakuba izinqubo ze-silicon-based optoelectronics ziyinkimbinkimbi kunezogesi ezithuthukisiwe ze-CMOS, ukuzuza ukusebenza okuzinzile nokukhiqiza kudinga ubuchwepheshe obubalulekile kanye nokwenza ngcono inqubo yokukhiqiza.

Iqhutshwa yi-AI boom kanye nezici ze-geopolitical, lo mkhakha uthola ukutshalwa kwezimali okukhuphukile okuvela kohulumeni, izimboni kanye nezinkampani ezizimele emhlabeni jikelele, kudala amathuba amasha okubambisana phakathi kwezemfundo nezimboni futhi kuthembisa ukusheshisa ukusungula izinto ezintsha.
