Silicon Photonics Yogwira

Photonanics Yogwira ntchito imanenanso mwachindunji njira zopangitsira mwadala mwadala pakati pa kuwala ndi zinthu. Gawo logwira ntchito ku Phototonics ndi njira yosinthira. Silicon yonse yaposachedwamakonzedwe owoneka bwinozimakhazikitsidwa pa plasma mwaulere. Kusintha kuchuluka kwa mabowo a ma elekitiro a Silicon ndi Douctic, njira zamagetsi amatha kusintha mawonekedwe ake owoneka bwino (1,2) omwe amapezeka mu equation (1,2) omwe amapezeka mu equation (1,2) omwe amapezeka ndi mawonekedwe oyenera (1,2) omwe amawonetsedwa ndi zokwanira kuchokera ku Soref (1,2) zomwe zawonetsedwa ndi zidziwitso zochokera ku Soref ndi ma nanometter a 1550 nanometer. Poyerekeza ndi mabowo a mabowo, zomwe zimapangitsa kuti muwone zenizeni zenizeni komanso zofanizira zosintha zenizeni, ndiye kuti, zimatha kupanga gawo lalikulu la kutayika kwa omwe aperekedwa, chonchoMach-zehnderndi oyimba mosinthana, nthawi zambiri amakondedwa kugwiritsa ntchito mabowo kuti apangegawo mosinthana.

ZosiyanasiyanaSilicon (SI) SinthaniMitundu ikuwonetsedwa mu Chithunzi 10A. Mu jakisoni wonyamula, kuwala kumapezeka mu silicon mkati mwa zikhomo zazikulu kwambiri, ndipo ma elekitoni ndi mabowo amalowetsedwa. Komabe, ma modzimatu amakhala pang'onopang'ono, omwe amakhala ndi bandwidth wa 500 mhz, chifukwa mabowo amasuluka amatenga nthawi yayitali kubweza jakisoni. Chifukwa chake, mawonekedwe awa nthawi zambiri amagwiritsidwa ntchito ngati chingwe chosinthika chosinthika (VOA) m'malo mongotor. Mu chonyamulira cholefuka, gawo la kuwalako limapezeka mu chipwirikiti cha PN, ndipo m'lifupi mwake m'matumba a PNGER amasinthidwa ndi gawo lamagetsi. Izi zimatha kugwira ntchito mothamanga kwambiri. VPPIL ndi 2 V-cm. A Oxadide wa zitsulo (motion) (mode (kwenikweni Semiconductortioct-Oxidi-Semiconductor) ramilator) Zimaloleza kudzikundikira kwa chonyamulira komanso kunyamula, kulola phomble yocheperako pafupifupi 0.2 VM, koma ali ndi vuto la zotayika kwambiri komanso kutalika kwakukulu pa ule. Kuphatikiza apo, pali mayamwidwe a SIG Electronical redisators ochokera ku SAG (Silicon Germanium Almoy) gulu la Barm. Kuphatikiza apo, pali graphene rafingeors omwe amadalira graphene kuti ayike pakati pa zitsulo zonyamula ndi ogwiritsa ntchito owonjezera. Izi zikuwonetsa mitundu yosiyanasiyana ya njira zosiyanasiyana zothanirana ndi kuthamanga kwambiri, kutayika kotsika kotsika kwambiri.

Chithunzi 10:

Zowunikira zingapo zowunikira za silicon zimawonetsedwa mu Chithunzi 10B. Zinthu zokongola ndi Germanium (Ge). Geyu amatha kuyamwa kuwala kotsika mpaka ma microns 1.6. Chikuwonetsedwa kumanzere ndiye mawonekedwe abwino kwambiri a malonda masiku ano. Imapangidwa ndi licon dopton yomwe imamera. Ge ndi SI ili ndi cholakwika cha 4% cha 4%, ndipo kuti muchepetse kusungunuka, woonda woonda woyamba wamkulu ngati buffer wosanjikiza. Dongosolo la N-Tym limachitika pamwamba pa gee wosanjikiza. Chitsulo-semiconductor-chitsulo (msm) Photodioded akuwonetsedwa pakati, komanso apd (Chithunzithunzi cha Avalche) Amawonetsedwa kumanja. Chigawo cha Apdche ku APD chimapezeka mu si, chomwe chili ndi phokoso lotsika poyerekeza ndi dera la Avanche m'magulu a III-v Zabwino.

Pakadali pano, palibe njira zothetsera zabwino zophatikizira zokometsera zopepuka ndi silika. Chithunzi 11 chikuwonetsa njira zingapo zomwe zingachitike ndi misonkhano yamisonkhano. Kumanzere kumanzere ndi kuphatikizidwa kwa monolithic komwe kumaphatikizapo kugwiritsa ntchito grosemain grewmaum (Ge) ngati ma veside owoneka bwino), ndi Alyo3, omwe amafunikira kupondapomko kwa galasi) Nyanja yotsatira imakhala yotsika kwambiri ku msonkhano wodziwika, kuphatikiza kulumikizana ndi ozizira mu III-V Gulu Lambiri. Mbali yotsatirayi ndi msonkhano wotsatira wa chip, womwe umakonda kuphatikizira chip a iii-v Ubwino wa njira zitatu zoyambirirazi ndikuti chipangizocho chikhoza kukhala ntchito mokwanira mkati mwa chofewa musanadutse. Msonkhano waukulu kwambiri ndi msonkhano wa chip-chip, kuphatikizapo kulumikizana mwachindunji kwa siyicon tchipisi kwa IIIC-V Zomwe zimachitika pakugwiritsa ntchito malonda poyenda kumanzere kupita kumanzere kwa tchati chakumapeto kwa kuphatikiza.

Chithunzi 11: Kodi phindu lake limaphatikizidwa ndi zithunzi za silicon? Mukamachoka kumanzere kupita kumanja, kupanga malo opanga pang'onopang'ono kumasuntha.
