Chimodzi mwazinthu zofunikira kwambiri za kusinthidwe kosinthika ndi kuthamanga kwake kapena bandwidth, komwe kuyenera kukhala kosatha monga zamagetsi omwe alipo. Omasulira omwe amakhala ndi maulendo omasulira bwino pamwamba pa 100 ghz awonetsedwa kale muukadaulo wa 90 NM E silicon, ndipo liwiro liwonjezeka kuti kukula kwa mawonekedwe ocheperako amachepetsedwa [1]. Komabe, bandwidth ya matchulato-daicon-roduces okhala ndi malire. Silika sakhala ndi χ (2) - -no konlinearity chifukwa cha mawonekedwe ake a centro-symmetrine. Kugwiritsa ntchito silicon yopsompsondikitsidwa kwadzetsa zotsatira zosangalatsa [2], koma osadziwa sakuvomereza zida zothandiza. Boma la Art Linnicon Photonotors motero limadalirabe kupezeka kwaulere mu PN kapena PEPTE (3-5]. Zovuta zomwe zidawonetsedwa zikuwonetsedwa kuti ziwonetsetse kuti ziwonetsero zam'madzi zotsika ngati vπl = 0.36 v mm, koma kuthamanga kwa kusintha kumachepa ndi Mphamvu za onyamula minofu. Komabe, kuchuluka kwa makonda a 10 Gbit / s zapangidwa mothandizidwa ndi chisanachitike chizindikiro chamagetsi [4]. Kugwiritsa ntchito kusinthanitsa komwe kumabwezeretserani m'malo mwake, bandwidth yawonjezeka pafupifupi 30 ghz [5,6], koma volt] Tsoka ilo, ma plasma otere a altulators amatulutsa mawu osasinthika komanso osagwirizana ndi magetsi omwe amagwiritsidwa ntchito. Kusintha Kwanjala Ngati Qam kumafunikira, komabe, yankho la mzere ndi gawo la malo omasulira, kupangitsa kuti kugwiritsidwa ntchito kwa electro-optro-optro (1]) makamaka zofunika.
2. Njira ya sohh
Posachedwa, siyicnon-orbidic hybrid (soh) yalembedwa [9-12]. Chitsanzo cha soh moddulator akuwonetsedwa mu mkuyu. 1 (a). Ili ndi malo owombera potsogolera munda wamakono, ndipo mizere iwiri ya silicon yomwe imalumikiza mawonedwe owoneka bwino ku ma electrodes. Ma elekitirodi amapezeka kunja kwa malo owoneka owoneka bwino kuti apewe kutayika kwa makope [13], mkuyu. 1 (b). Chipangizocho chimakutidwa ndi zinthu zopangira ma electro-optor zomwe zimadzazanso. Magetsi osinthika amatengedwa ndi zitsulo zamagetsi zakumagetsi ndikugwetsa kudutsa malo othokoza a silika. Zotsatira zamagetsi zimasintha njira yotetezera mu slot kudzera mu ultra-gread electro-optic. Popeza malowo ali ndi m'lifupi mwake mu dongosolo la 100 nm, ma volts ochepa amakhala okwanira kupanga minda yolimba yokhazikika yomwe ili mu dongosolo lamphamvu kwambiri yazinthu zambiri. Kapangidwe kake kamakhala ndi vuto mosinthasintha kuyambira onse osintha ndi mawonedwe am'madzi amakhazikika mkati mwa slot, mkuyu. 1 (1 (14). Inde, kukhazikitsa koyamba kwa sohu modlulators ndi Sub-volt Cat-11] zawonetsedwa kale, ndipo sangodanadayo mpaka 40 GHz idawonetsedwa [15,16]. Komabe, zovuta zomwe zimapangidwa pomanga mafuta otsika kwambiri moddulasitors othamanga ndikupanga mzere wolumikizana kwambiri. Mu gawo lofanana ndi slot imatha kuyimitsidwa ndi capocator c ndi zolengedwa zoyipa mwa kukana r, mkuyu. 1 (b). Nthawi yofananira RC Nthawi zonse imazindikira gulu lankhondo [10,14,18,18]. Kuti muchepetse kukana R, kwakuti afotokozedwe kuti athetse zitsimikiziro [10,14]. Pomwe dopati ikuwonjezera mawonekedwe a zikwangwani za silika (chifukwa chake zimawonjezera kutaya kowoneka bwino) Kuphatikiza apo, zoyeserera zaposachedwa kwambiri zidawonetsa moyo wosayembekezeka.
Beijing Rofea Optoectronicts Comlent Conseponics Couchley "ya China" - Isiicicon Zhongoancun, ndi bizinesi yapamwamba yophunzitsira anthu, mayunitsezi akunja, mayunitsezi Kampani yathu makamaka imachitika makamaka pofufuza komanso kukhazikika, kupanga, kugulitsa zinthu zina zojambula, ndipo zimapereka njira zosinthira ndi akatswiri ofufuza zasayansi komanso amapanga mafakitale. Pambuyo pazaka zambiri zodziyimira pawokha, zapanga mndandanda wazinthu zolemera komanso zabwino kwambiri m'maboma, ankhondo, oyendetsa, mayendedwe, mphamvu yamagetsi, mafakitale ambiri.
Tikuyembekezera mgwirizano ndi inu!
