Ramangwana reelectro optical modulators
Electro optic modulators inoita basa repakati mune zvemazuva ano optoelectronic masisitimu, ichiita basa rakakosha muminda yakawanda kubva pakutaurirana kuenda kuquantum computing nekudzora zvimiro zvechiedza. Iri bepa rinokurukura mamiriro azvino, budiriro yazvino uye kuvandudza kweramangwana kwe electro optic modulator tekinoroji
Mufananidzo 1: Kuenzanisa kwekuita kwezvakasiyanaOptical modulatormatekinoroji, anosanganisira akaonda firimu lithium niobate (TFLN), III-V yemagetsi absorption modulators (EAM), silicon-based uye polymer modulators maererano nekuisa kurasikirwa, bandwidth, kushandiswa kwesimba, saizi, uye kugona kugadzira.
Traditional silicon-yakavakirwa electro optic modulators uye nezvaasingakwanisi
Silicon-based photoelectric light modulators yanga iri hwaro hwe optical communication system kwemakore mazhinji. Zvichienderana neiyo plasma dispersion effect, michina yakadai yakaita fambiro mberi inoshamisa mumakore makumi maviri neshanu apfuura, ichiwedzera mazinga ekufambisa data nemirairo mitatu yehukuru. Mazuva ano silicon-based modulators inogona kuwana 4-level pulse amplitude modulation (PAM4) inosvika 224 Gb/s, uye kunyange kupfuura mazana matatu Gb/s ine PAM8 modulation.
Nekudaro, ma-silicon-based modulators anotarisana neakakosha zvimisikidzo zvinobva kuzvinhu zvenyama. Kana ma transceivers optical anoda ma baud rates anodarika 200+ Gbaud, bandwidth yemidziyo iyi yakaoma kuzadzisa zvinodiwa. Uku kudzikisira kunobva kune zvakasikwa zvivakwa zvesilicon - chiyero chekudzivirira kurashikirwa kwechiedza chakanyanya uku uchichengetedza conductivity yakakwana inogadzira kutengeserana kusingadzivisike.
Emerging modulator tekinoroji uye zvinhu
Izvo zvinogumira zvechinyakare silicon-based modulators zvakamhanyisa kutsvagisa mune zvimwe zvinhu uye yekubatanidza matekinoroji. Thin film lithium niobate yave imwe yemapuratifomu anovimbisa echizvarwa chitsva che modulators.Mutete firimu lithium niobate electro-optic modulatorsgara nhaka yakanakisa hunhu hweakawanda lithium niobate, kusanganisira: yakafara hwindo hwindo, hombe electro-optic coefficient (r33 = 31 pm/V) linear cell Kerrs mhedzisiro inogona kushanda mune akawanda wavelength renji.
Kufambira mberi munguva pfupi yapfuura mufirimu yakatetepa lithium niobate tekinoroji yakaunza mhedzisiro inoshamisa, kusanganisira modulator inoshanda pa260 Gbaud ine data reti ye1.96 Tb/s pachiteshi. Iyi puratifomu ine yakasarudzika mabhenefiti akadai seCMOS-inoenderana drive voltage uye 3-dB bandwidth ye100 GHz.
Emerging tekinoroji application
Iko kuvandudzwa kwe electro optic modulators kwakabatana zvakanyanya nezviri kubuda mundima dzakawanda. Mumunda wehungwaru hwekugadzira uye nzvimbo dzedata,high-speed modulatorszvakakosha kuchizvarwa chinotevera chekubatanidza, uye AI computing applications iri kutyaira kudiwa kwe800G uye 1.6T pluggable transceivers. Modulator tekinoroji inoshandiswawo kune: quantum information processing neuromorphic computing Frequency modulated continuous wave (FMCW) lidar microwave photon tekinoroji.
Kunyanya, firimu rakatetepa lithium niobate electro-optic modulators inoratidza simba mune optical computational processing injini, ichipa kukurumidza kuderera-simba modulation inomhanyisa kudzidza kwemuchina uye hunyanzvi hwekushandisa. Mamodulator akadaro anogona zvakare kushanda pakadzika tembiricha uye akakodzera quantum-classical interfaces mu superconducting mitsetse.
Kuvandudzwa kwechizvarwa chinotevera electro optic modulators kunotarisana nematambudziko akati wandei: Mutengo wekugadzira uye chiyero: mutete-firimu lithium niobate modulators parizvino anogumira ku150 mm wafer kugadzirwa, zvichikonzera mutengo wakakwira. Iyo indasitiri inoda kuwedzera saizi yewafer uku ichichengetedza kufanana kwemafirimu uye mhando. Kubatanidzwa uye Co-dhizaini: Kubudirira kubudirira kwehigh-performance modulatorsinoda huwandu hwakakwana hwekugadzira hunyanzvi, hunosanganisira kubatana kweoptoelectronics uye vagadziri vemagetsi chip, vatengesi veEDA, matsime, uye nyanzvi dzekurongedza. Kugadzira kuomarara: Nepo silicon-yakavakirwa optoelectronics maitiro asina kuomarara pane epamberi CMOS zvemagetsi, kuwana yakagadzikana kuita uye goho kunoda hunyanzvi hwakakosha uye kugadzirisa maitiro ekugadzira.
Inotungamirwa neAI boom uye geopolitical zvinhu, munda uri kugamuchira yakawedzera mari kubva kuhurumende, indasitiri neyakazvimiririra kutenderera pasirese, ichigadzira mikana mitsva yekubatana pakati pevadzidzi neindasitiri uye ichivimbisa kukurumidza hunyanzvi.
