Remangwana remamodulator emagetsi emagetsi

Ma electro optic modulators anoita basa guru mumasisitimu emazuva ano e optoelectronic, achiita basa rakakosha muminda yakawanda kubva pakutaurirana kusvika pa quantum computing nekudzora hunhu hwechiedza. Pepa rino rinotaura nezvemamiriro aripo iye zvino, kubudirira kwazvino uye kuvandudzwa mune ramangwana kwetekinoroji ye electro optic modulator.

Mufananidzo 1: Kuenzanisa mashandiro emhando dzakasiyana dzemodulator yemazisomatekinoroji, anosanganisira thin film lithium niobate (TFLN), III-V electrical absorption modulators (EAM), silicon-based uye polymer modulators maererano nekurasikirwa kweinsertion, bandwidth, simba rinoshandiswa, saizi, uye kugona kugadzira.

Mamodulator emagetsi e-electro optic akavakirwa pasilicon uye zvaasingakwanisi kuita

Mamodulators echiedza chephotoelectric akavakirwa pasilicon ave ari hwaro hwemasisitimu ekutaurirana kwemaziso kwemakore mazhinji. Zvichibva pamhedzisiro yekupararira kweplasma, zvishandiso zvakadaro zvakafambira mberi zvinoshamisa mumakore makumi maviri nemashanu apfuura, zvichiwedzera mwero wekutamiswa kwedata nematanho matatu ehukuru. Mamodulators emazuva ano akavakirwa pasilicon anogona kuwana 4-level pulse amplitude modulation (PAM4) inosvika 224 Gb/s, uye kunyange anopfuura 300 Gb/s nePAM8 modulation.

Zvisinei, ma modulators akavakirwa pa silicon anosangana nemiganhu mikuru inobva muhunhu hwezvinhu. Kana ma transceiver e optical achida mwero we baud unopfuura 200+ Gbaud, bandwidth yemidziyo iyi inonetsa kusangana nezvinodiwa. Muganho uyu unobva muhunhu hwe silicon - chiyero chekudzivirira kurasikirwa nechiedza zvakanyanya uku uchichengetedza conductivity yakakwana chinoita kuti pave nekuchinjana kusingadzivisike.

Tekinoroji ye modulator iri kubuda uye zvinhu

Kusakwana kwema modulators echinyakare akavakirwa pasilicon kwakaita kuti pave nekutsvagurudza mune zvimwe zvinhu uye matekinoroji ekubatanidza. Thin film lithium niobate yave imwe yemapuratifomu ane tariro zvikuru kune chizvarwa chitsva chema modulators.Mafirimu matete e lithium niobate electro-optic modulatorsgara nhaka hunhu hwakanaka hwe bulk lithium niobate, kusanganisira: hwindo rakafara rakajeka, electro-optic coefficient hombe (r33 = 31 pm/V) linear cell Kerrs effect inogona kushanda munzvimbo dzakasiyana-siyana dze wavelength.

Kufambira mberi kwazvino mu tekinoroji ye lithium niobate yakaburitsa mhedzisiro inoshamisa, kusanganisira modulator inoshanda pa260 Gbaud ine data rates ye1.96 Tb/s pachiteshi chimwe nechimwe. Puratifomu iyi ine zvakanakira zvakasiyana zvakaita seCMOS-compatible drive voltage uye 3-dB bandwidth ye100 GHz.

Chishandiso chetekinoroji chiri kubuda

Kugadzirwa kwema electro optic modulators kwakabatana zvakanyanya nemashandisirwo ari kuenderera mberi muminda yakawanda. Mumunda we artificial intelligence nenzvimbo dzedata,mamodulators anomhanya kwazvodzakakosha kuchizvarwa chinotevera chekubatana, uye mashandisirwo eAI computing ari kukurudzira kudiwa kwema transceivers e800G ne1.6T anodzvanywa. Tekinoroji yemodulator inoshandiswawo ku: quantum information processing neuromorphic computing Frequency modulated continuous wave (FMCW) lidar microwave photon technology

Zvikuru sei, ma "thin film lithium niobate electro-optic modulators" anoratidza simba muma "optical computational processing engines", achipa "low-power modulation" inokurumidza kukurumidza kudzidza kwemuchina uye mashandisirwo ehungwaru hwekugadzira. Ma "modulators" akadaro anogonawo kushanda patembiricha yakaderera uye akakodzera ma "quantum-classical interfaces" mu "superconducting lines".

Kugadzirwa kwema electro optic modulators echizvarwa chinotevera kunosangana nematambudziko makuru akati wandei: Mutengo wekugadzira uye kukura: ma thin-film lithium niobate modulators parizvino akaganhurirwa pakugadzirwa kwe 150 mm wafer, zvichikonzera mitengo yakakwira. Indasitiri iyi inoda kuwedzera saizi ye wafer uku ichichengetedza kufanana uye mhando yefirimu. Kubatanidzwa uye Kubatanidzwa: Kubudirira kwekuvandudzwa kwema modulators anoshanda zvakanyanyainoda hunyanzvi hwakakwana hwekugadzira pamwe chete, hunosanganisira kushanda pamwe chete kwevanogadzira ma optoelectronics nevagadziri vemachipisi emagetsi, vatengesi veEDA, ma founts, uye nyanzvi dzekurongedza. Kuoma kwekugadzira: Kunyange hazvo maitiro e optoelectronics akavakirwa pasilicon asina kuoma kupfuura eCMOS electronics yepamusoro, kuwana kushanda kwakasimba uye goho kunoda hunyanzvi hwakakura uye kugadzirisa maitiro ekugadzira.

Nekuda kwekukura kweAI uye geopolitical factors, basa iri riri kuwana mari yakawanda kubva kuhurumende, maindasitiri nemasangano akazvimirira pasi rese, zvichigadzira mikana mitsva yekushandira pamwe pakati pedzidzo nemaindasitiri uye zvichivimbisa kukurumidzisa hunyanzvi hutsva.
