Tsogolo la ma modulators amagetsi

Tsogolo lama modulators amagetsi

Ma electro optic modulators amachita gawo lalikulu m'makina amakono a optoelectronic, akuchita gawo lofunika kwambiri m'magawo ambiri kuyambira pa kulumikizana mpaka pa quantum computing mwa kuwongolera mawonekedwe a kuwala. Pepalali likufotokoza momwe zinthu zilili panopa, kupita patsogolo kwaposachedwa komanso chitukuko chamtsogolo cha ukadaulo wa electro optic modulator.

Chithunzi 1: Kuyerekeza magwiridwe antchito a mitundu yosiyanasiyanamodulator yowalaukadaulo, kuphatikizapo thin film lithium niobate (TFLN), III-V electrical absorption modulators (EAM), silicon-based ndi polymer modulators pankhani ya kutayika kwa insertion, bandwidth, mphamvu yogwiritsidwa ntchito, kukula, ndi mphamvu zopangira.

Ma modulators achikhalidwe opangidwa ndi silicon ndi zofooka zawo

Ma modulators a kuwala kwa photoelectric ochokera ku silicon akhala maziko a machitidwe olumikizirana kwa zaka zambiri. Kutengera ndi mphamvu ya plasma dispersion, zipangizo zotere zapita patsogolo kwambiri m'zaka 25 zapitazi, zomwe zawonjezera kuchuluka kwa kusamutsa deta ndi magulu atatu akuluakulu. Ma modulators amakono ochokera ku silicon amatha kukwaniritsa 4-level pulse amplitude modulation (PAM4) mpaka 224 Gb/s, komanso kuposa 300 Gb/s ndi PAM8 modulation.

Komabe, ma modulators opangidwa ndi silicon amakumana ndi zofooka zazikulu zomwe zimachokera ku zinthu zakuthupi. Pamene ma transceiver optical amafunikira kuchuluka kwa baud kopitilira 200+ Gbaud, bandwidth ya zida izi imakhala yovuta kukwaniritsa kufunikira kwake. Kuchepa kumeneku kumachokera ku makhalidwe enieni a silicon - kuletsa kutayika kwa kuwala kwambiri pamene kusunga ma conductivity okwanira kumapanga kusintha kosapeŵeka.

Ukadaulo watsopano wa modulator ndi zipangizo zake

Zofooka za ma modulators achikhalidwe opangidwa ndi silicon zapangitsa kuti kafukufuku apezeke pazinthu zina ndi ukadaulo wophatikiza. Thin film lithium niobate yakhala imodzi mwa nsanja zabwino kwambiri za mbadwo watsopano wa ma modulators.Ma modulators a lithiamu niobate electro-optic optic a filimu yopyapyalacholowa makhalidwe abwino kwambiri a bulk lithium niobate, kuphatikizapo: zenera lowonekera bwino, electro-optic coefficient yayikulu (r33 = 31 pm/V) linear cell Kerrs effect imatha kugwira ntchito m'malo osiyanasiyana a wavelength

Kupita patsogolo kwaposachedwa kwa ukadaulo wa lithiamu niobate wa filimu yopyapyala kwapereka zotsatira zabwino kwambiri, kuphatikizapo modulator yomwe imagwira ntchito pa 260 Gbaud yokhala ndi kuchuluka kwa deta ya 1.96 Tb/s pa njira iliyonse. Pulatifomuyi ili ndi zabwino zapadera monga magetsi oyendetsera CMOS ndi bandwidth ya 3-dB ya 100 GHz.

Kugwiritsa ntchito ukadaulo watsopano

Kupanga ma electro optic modulators kukugwirizana kwambiri ndi ntchito zomwe zikubwera m'magawo ambiri. Mu gawo la nzeru zopanga zinthu ndi malo osungira deta,ma modulators othamanga kwambirindi ofunikira kwambiri pa mibadwo yotsatira yolumikizana, ndipo mapulogalamu a AI computing akuyendetsa kufunikira kwa ma transceivers a 800G ndi 1.6T pluggable. Ukadaulo wa modulator umagwiritsidwanso ntchito pa: kukonza zambiri za quantum kuwerengera ubongo kuwerengera mafunde opitilira (FMCW) ukadaulo wa photon wa microwave lidar

Makamaka, ma modulators a lithiamu niobate electro-optic omwe ali ndi filimu yopyapyala amasonyeza mphamvu mu mainjini opangira makompyuta, zomwe zimapereka kusintha kwachangu kwa mphamvu zochepa komwe kumathandizira kuphunzira kwa makina ndi kugwiritsa ntchito luntha lochita kupanga. Ma modulators otere amathanso kugwira ntchito kutentha kochepa ndipo ndi oyenera ma interfaces a quantum-classical mu mizere ya superconducting.

Kupanga ma modulators a electro optic a m'badwo wotsatira kukukumana ndi mavuto akuluakulu angapo: Mtengo ndi kukula kwa kupanga: ma modulators a lithiamu niobate omwe ali ndi filimu yopyapyala pakadali pano ali ndi malire pakupanga ma wafer a 150 mm, zomwe zimapangitsa kuti ndalama zikwere. Makampaniwa akuyenera kukulitsa kukula kwa ma wafer pamene akusunga kufanana ndi khalidwe la filimu. Kuphatikizana ndi Kupangana: Kukula kopambana kwama modulators ogwira ntchito kwambirikumafuna luso lonse lopanga zinthu pamodzi, kuphatikizapo mgwirizano wa opanga ma optoelectronics ndi ma chip amagetsi, ogulitsa ma EDA, ma founts, ndi akatswiri opaka. Kuvuta kupanga: Ngakhale njira za ma optoelectronics zochokera ku silicon sizovuta kwambiri kuposa zamagetsi apamwamba a CMOS, kukwaniritsa magwiridwe antchito okhazikika ndi kukolola kumafuna ukatswiri wofunikira komanso kukonza njira zopangira.

Chifukwa cha kukula kwa luso la AI komanso zinthu zandale, ntchitoyi ikulandira ndalama zambiri kuchokera ku maboma, mafakitale ndi mabungwe achinsinsi padziko lonse lapansi, zomwe zikupanga mwayi watsopano wogwirizana pakati pa maphunziro ndi mafakitale ndikulonjeza kuti zinthu zatsopano zipitirire patsogolo.
