Ahazaza h'ibikoresho by'amashanyarazi bikoresha amashanyarazi

Ahazaza hamodulators z'amashanyarazi

Udukoresho twa Electro optique tugira uruhare runini muri sisitemu zigezweho za optoelectronic, bigira uruhare runini mu nzego nyinshi kuva ku itumanaho kugeza ku kubara kwa quantum binyuze mu kugenzura imiterere y'urumuri. Iyi nyandiko ivuga ku miterere y'ubu, iterambere rigezweho n'iterambere ry'ejo hazaza ry'ikoranabuhanga rya electro optique modulator.

Igishushanyo cya 1: Igereranya ry'imikorere y'ibintu bitandukanyemodulator y'izubaikoranabuhanga, harimo icyuma gito cya lithium niobate (TFLN), modulators z’amashanyarazi za III-V (EAM), modulators zishingiye kuri silicon na polymer mu bijyanye no gutakaza ingufu, bandwidth, ikoreshwa ry’ingufu, ingano, n’ubushobozi bwo gukora.

Modulator zikoresha electro optique zishingiye kuri silicon gakondo n'imbogamizi zazo

Utwuma dukoresha urumuri rw'amashanyarazi dushingiye kuri silicon twamaze imyaka myinshi ari ishingiro rya sisitemu y'itumanaho ry'urumuri. Hashingiwe ku ngaruka zo gukwirakwira kwa plasma, ibikoresho nk'ibi byateye imbere cyane mu myaka 25 ishize, byongera umuvuduko wo kohereza amakuru ku rugero rutatu rw'ubunini. Utwuma dukoresha silicon dukoresha silicon dushobora kugera ku muvuduko wa pulse amplitude modulation wa 4-level (PAM4) kugeza kuri 224 Gb/s, ndetse na Gb/s zirenga 300 hamwe na modulation ya PAM8.

Ariko, modulators zishingiye kuri silicon zihura n'imbogamizi z'ibanze zikomoka ku miterere y'ibikoresho. Iyo transceivers z'amajwi zisaba igipimo cya baud kirenga 200+ Gbaud, bandwidth y'ibi bikoresho iragoye guhaza ibyifuzo. Iyi mbogamizi ituruka ku miterere y'umwimerere ya silicon - uburinganire bwo kwirinda gutakaza urumuri rwinshi mu gihe ukomeza gukoresha amashanyarazi ahagije butuma habaho impinduka zitari ngombwa.

Ikoranabuhanga n'ibikoresho bishya bya modulator

Inzitizi z’ibikoresho bisanzwe bikoresha silikoni byatumye ubushakashatsi ku bikoresho n’ikoranabuhanga ryo guhuza ibikoresho. Thin film lithium niobate yabaye imwe mu mbuga zitanga icyizere ku gisekuru gishya cy’ibikoresho bikoresha silikoni.Modulators za electro-optic za lithium niobate zikozwe muri firime ntokuragwa imiterere myiza ya lithium niobate, harimo: idirishya rinini ribonerana, coefficient nini ya electro-optic (r33 = 31 pm/V) linear cell Kerrs effect ishobora gukora mu byiciro byinshi by'uburebure

Iterambere riherutse mu ikoranabuhanga rya lithium niobate rya thin film ryatanze umusaruro utangaje, harimo modulator ikora kuri 260 Gbaud ifite igipimo cy'amakuru cya 1.96 Tb/s kuri buri muyoboro. Uru rubuga rufite ibyiza bidasanzwe nka voltage ihuza na CMOS na bandwidth ya 3-dB ya 100 GHz.

Porogaramu y'ikoranabuhanga igezweho

Iterambere rya modulator za electro optique rifitanye isano rya hafi n'ikoreshwa rishya mu nzego nyinshi. Mu rwego rw'ubwenge bw'ubukorano n'ibigo by'amakuru,modulators zihuta cyaneni ingenzi ku iterambere ry’ikoranabuhanga ritaha, kandi porogaramu za mudasobwa za AI zirimo gutuma abantu benshi bakenera transceivers za 800G na 1.6T zishobora gucomeka. Ikoranabuhanga rya modulator rikoreshwa kandi kuri: gutunganya amakuru ya quantum. Kubara imikorere ya neuromorphic. Ikoranabuhanga rya microwave fotoni rikozwe mu buryo bwa Frequency modulated continuous wave (FMCW)

By’umwihariko, modulators za lithium niobate electro-optic zigaragaza imbaraga muri moteri zitunganya ikoranabuhanga rya optique, zitanga modulation yihuta y’ingufu nke yihutisha ikoreshwa ry’imashini mu kwiga no mu bumenyi bw’ubukorano. Izo modulators zishobora kandi gukora ku bushyuhe buke kandi zikwiriye imiyoboro ya quantum-classical mu miyoboro ya superconducting.

Iterambere rya modulator za electro optique zo mu gisekuru gitaha rihura n'imbogamizi nyinshi zikomeye: Ikiguzi n'ingano y'umusaruro: modulator za lithium niobate zikozwe muri thin-film ubu zigarukira ku musaruro wa wafer wa mm 150, bigatuma ibiciro byiyongera. Inganda zigomba kwagura ingano ya wafer mu gihe zigumana ubwiza n'ubuziranenge bwa filime. Guhuza no gushushanya hamwe: Iterambere ryiza ryamodulator zikora neza cyanebisaba ubushobozi busesuye bwo gushushanya hamwe, burimo ubufatanye bw'abahanga mu by'ikoranabuhanga n'abashushanya chips z'ikoranabuhanga, abatanga serivisi za EDA, founts, n'inzobere mu gupakira. Ubuhanga mu gukora: Nubwo inzira za optoelectronics zishingiye kuri silicon zidagoye cyane ugereranyije n'ibikoresho bya elegitoroniki bya CMOS bigezweho, kugera ku musaruro uhamye no kuvugurura uburyo bwo gukora bisaba ubuhanga buhambaye.

Bitewe n’iterambere ry’ikoranabuhanga rya siyansi n’ikoranabuhanga (AI) hamwe n’ibintu bya politiki y’isi, uru rwego rurimo kubona ishoramari ryinshi riturutse muri za leta, inganda n’abikorera ku giti cyabo hirya no hino ku isi, bitanga amahirwe mashya yo gukorana hagati y’amashuri makuru n’inganda kandi bisezeranya kwihutisha udushya.
