Impinduramatwara-silicon Photodetector （Si Photodetector, Imikorere irenze gakondo

Hamwe no kwiyongera kwingero zubwenge bwubuhanga hamwe numuyoboro wimbitse wubwonko, cluster yo kubara ishyira hejuru cyane itumanaho ryurusobe hagati yabatunganya, kwibuka hamwe na compte node. Nyamara, imiyoboro gakondo kuri chip na interineti ihuza imiyoboro ishingiye ku mashanyarazi ntiyashoboye guhaza ibyifuzo bikenerwa n’umurongo mugari, ubukererwe no gukoresha amashanyarazi. Kugirango dukemure iki kibazo, tekinoroji ya optique ihuza intera ndende yayo, umuvuduko wihuse, ibyiza byo gukoresha ingufu, buhoro buhoro bihinduka ibyiringiro byiterambere. Muri byo, tekinoroji ya silicon Photonic ishingiye kubikorwa bya CMOS yerekana ubushobozi bukomeye bitewe no kwishyira hamwe kwayo, kugiciro gito no gutunganya neza. Ariko, gutahura imikorere yimikorere ya Photodetector iracyafite ibibazo byinshi. Mubisanzwe, fotodetekitori igomba guhuza ibikoresho hamwe nu cyuho gito, nka germanium (Ge), kugirango imikorere irusheho kumenyekana, ariko ibi kandi biganisha kubikorwa bigoye cyane byo gukora, ibiciro byinshi, numusaruro udakwiye. Photodetector ya silicon yose yakozwe nitsinda ryubushakashatsi yageze ku muvuduko wo kohereza amakuru kuri 160 Gb / s kuri buri muyoboro udakoresheje germanium, hamwe n’umuyoboro mugari wa 1.28 Tb / s, binyuze mu gishushanyo mbonera cya mikorobe ebyiri.

Vuba aha, itsinda ry’ubushakashatsi ryahurijwe hamwe muri Amerika ryasohoye ubushakashatsi bushya, butangaza ko bakoze neza fotodiode ya silicon yose ya silicon (APD ifotora) chip. Iyi chip ifite umuvuduko mwinshi cyane hamwe nigiciro gito cyamafoto yumuriro wa interineti, biteganijwe ko uzagera kuri 3.2 Tb kumasegonda yoherejwe mumasegonda ya optique.

Iterambere rya tekiniki: igishushanyo mbonera cya microring resonator

Gufotora gakondo akenshi bifite kwivuguruza kutavuguruzanya hagati yumurongo mugari no kwitabira. Itsinda ry’ubushakashatsi ryatsinze neza uku kwivuguruza hakoreshejwe igishushanyo mbonera cya resonator ebyiri kandi gihagarika ibiganiro byambukiranya imiyoboro. Ibisubizo byubushakashatsi byerekana kobyose-silicon Photodetectorifite igisubizo cya 0.4 A / W, umuyoboro wijimye uri munsi ya 1 nA, umuvuduko mwinshi wa 40 GHz, hamwe n’umuhanda muto cyane w'amashanyarazi uri munsi ya −50 dB. Iyi mikorere iragereranywa nubu fotodeteri yubucuruzi ishingiye kuri silicon-germanium nibikoresho bya III-V.

Urebye ahazaza: Inzira yo guhanga udushya mumiyoboro ya optique

Iterambere ryiza rya fotodetekeri ya silicon yose ntabwo ryarenze igisubizo gakondo mubuhanga gusa, ahubwo ryanageze ku kuzigama hafi 40% yikiguzi, biha inzira inzira yo kubona imiyoboro yihuse, ihendutse kandi ihendutse mugihe kizaza. Ikoranabuhanga rirahuza neza na gahunda ya CMOS isanzwe, ifite umusaruro mwinshi cyane n'umusaruro, kandi biteganijwe ko bizahinduka ikintu gisanzwe mubijyanye na tekinoroji ya silicon Photonics mugihe kizaza. Mu bihe biri imbere, itsinda ry’ubushakashatsi rirateganya gukomeza kunonosora igishushanyo mbonera kugira ngo turusheho kunoza igipimo cyo kwinjiza no kwaguka kwinshi kwa fotodetector mu kugabanya ingufu za doping no kunoza uburyo bwo gutera. Muri icyo gihe, ubushakashatsi buzanasuzuma uburyo ubwo buhanga bwa silikoni yose bwakoreshwa ku miyoboro ya optique mu bisekuruza bizaza bya AI kugira ngo bigere ku muvuduko mwinshi, ubunini kandi bukoreshwa neza.
