Ikusasa likaama-modulators e-electro optical
Ama-electro optic modulators adlala indima ebalulekile ezinhlelweni zesimanje ze-optoelectronic, edlala indima ebalulekile emikhakheni eminingi kusukela ekuxhumaneni kuya ekubenila kwe-quantum ngokulawula izakhiwo zokukhanya. Leli phepha lixoxa ngesimo samanje, impumelelo yakamuva kanye nentuthuko yesikhathi esizayo yobuchwepheshe be-electro optic modulator.
Umfanekiso 1: Ukuqhathaniswa kokusebenza kwezinhlobo ezahlukenei-modulator yokukhanyaubuchwepheshe, okuhlanganisa i-thin film lithium niobate (TFLN), ama-III-V electrical absorption modulators (EAM), ama-silicon-based kanye nama-polymer modulators maqondana nokulahlekelwa kokufakwa, i-bandwidth, ukusetshenziswa kwamandla, usayizi, kanye nomthamo wokukhiqiza.
Ama-modulators e-electro optic asekelwe ku-silicon yendabuko kanye nokulinganiselwa kwawo
Ama-modulators okukhanya kwe-photoelectric asekelwe ku-silicon abe yisisekelo sezinhlelo zokuxhumana ze-optical iminyaka eminingi. Ngokusekelwe kumphumela wokusabalala kwe-plasma, amadivayisi anjalo enze intuthuko emangalisayo eminyakeni engama-25 edlule, andisa amazinga okudlulisa idatha ngama-oda amathathu ngobukhulu. Ama-modulators anamuhla asekelwe ku-silicon angafinyelela i-4-level pulse amplitude modulation (PAM4) efinyelela ku-224 Gb/s, kanye nangaphezulu kuka-300 Gb/s nge-PAM8 modulation.
Kodwa-ke, ama-modulators asekelwe ku-silicon abhekene nemikhawulo eyisisekelo evela ezimpahleni zezinto ezibonakalayo. Lapho ama-transceiver e-optical edinga amazinga e-baud angaphezu kuka-200+ Gbaud, i-bandwidth yala madivayisi kunzima ukuhlangabezana nesidingo. Lo mkhawulo uvela ezimpahleni ezingokwemvelo ze-silicon - ibhalansi yokugwema ukulahlekelwa ukukhanya ngokweqile ngenkathi ugcina ukuhanjiswa okwanele kudala ukuhwebelana okungenakugwenywa.
Ubuchwepheshe be-modulator obusafufusa kanye nezinto zokwakha
Ukulinganiselwa kwama-modulators endabuko asekelwe ku-silicon kuye kwaholela ocwaningweni lwezinto ezihlukile kanye nobuchwepheshe bokuhlanganisa. I-Thin film lithium niobate isibe ngelinye lamapulatifomu athembisayo kakhulu esizukulwaneni esisha sama-modulators.Ama-modulators e-lithium niobate electro-optic efilimu encanezuza izici ezinhle kakhulu ze-bulk lithium niobate, okuhlanganisa: ifasitela elibanzi elibonakalayo, i-electro-optic coefficient enkulu (r33 = 31 pm/V) iseli eliqondile Umphumela we-Kerrs ungasebenza kumabanga amaningi we-wavelength
Intuthuko yakamuva kwezobuchwepheshe be-lithium niobate yefilimu encane iveze imiphumela emangalisayo, okuhlanganisa ne-modulator esebenza ku-260 Gbaud enamazinga edatha angu-1.96 Tb/s ngesiteshi ngasinye. Ipulatifomu inezinzuzo ezihlukile njenge-drive voltage ehambisana ne-CMOS kanye ne-bandwidth engu-3-dB ye-100 GHz.
Uhlelo lokusebenza lobuchwepheshe olusafufusa
Ukuthuthukiswa kwama-electro optic modulators kuhlobene kakhulu nezinhlelo zokusebenza ezintsha emikhakheni eminingi. Emkhakheni wezobunhloli bokwenziwa kanye nezikhungo zedatha,ama-modulators asheshayozibalulekile esizukulwaneni esilandelayo sokuxhumana, futhi izinhlelo zokusebenza zokubala ze-AI ziqhuba isidingo sama-transceivers axhunywayo angu-800G kanye no-1.6T. Ubuchwepheshe be-Modulator busetshenziswa futhi ku: ukucubungula ulwazi lwe-quantum ukubala i-neuromorphic i-frequency modulated continuous wave (FMCW) ubuchwepheshe be-lidar microwave photon
Ikakhulukazi, ama-modulators e-lithium niobate electro-optic abonisa amandla ezinjinini zokucubungula ze-optical computation, enikeza ukuguqulwa kwamandla aphansi okusheshayo okusheshisa ukufunda komshini kanye nezinhlelo zokusebenza zobuhlakani bokwenziwa. Ama-modulators anjalo angasebenza futhi emazingeni okushisa aphansi futhi afanelekela izixhumanisi ze-quantum-classical emigqeni ye-superconducting.
Ukuthuthukiswa kwama-electro optic modulator esizukulwane esilandelayo kubhekene nezinselele eziningana ezinkulu: Izindleko zokukhiqiza kanye nobukhulu: ama-thin-film lithium niobate modulator okwamanje anqunyelwe ekukhiqizweni kwe-wafer engu-150 mm, okuholela ezindleleni eziphakeme. Imboni idinga ukwandisa usayizi we-wafer ngenkathi igcina ukufana kwefilimu kanye nekhwalithi. Ukuhlanganiswa kanye nokuklama ngokubambisana: Intuthuko ephumelelayo yeama-modulators asebenza kahle kakhulukudinga amakhono aphelele okuklama ngokubambisana, okubandakanya ukubambisana kwabaklami be-optoelectronics kanye nabaklami be-chip kagesi, abaphakeli be-EDA, ama-founts, kanye nochwepheshe bokupakisha. Ubunzima bokukhiqiza: Nakuba izinqubo ze-optoelectronics ezisekelwe ku-silicon zingenzima kakhulu kune-elekthronikhi ye-CMOS ethuthukisiwe, ukufeza ukusebenza okuzinzile kanye nokukhiqiza kudinga ubuchwepheshe obukhulu kanye nokwenza ngcono inqubo yokukhiqiza.
Iqhutshwa ukuchuma kwe-AI kanye nezici zezwe, lo mkhakha uthola ukutshalwa kwezimali okwandisiwe okuvela kohulumeni, izimboni kanye nomkhakha ozimele emhlabeni wonke, okudala amathuba amasha okubambisana phakathi kwezemfundo kanye nezimboni futhi kuthembisa ukusheshisa ukusungula izinto ezintsha.
