I-42.7 GBICH / S Electro-Optic Podulator kwiTekhnoloji yaseSilicon

Enye yezona ndawo zibalulekileyo zomthambo obalulekileyo yisantya sayo semodyuli okanye i-bandwidth, ekufuneka ibekho ngokukhawuleza njengee-elektroniki. Abahambileyo banesantya sokuhamba ngaphezulu kwe-100 i-GHZ sele kuboniswe kwiTekhnoloji ye-90 ye-70 ye-NM, kwaye isantya siya kwandiswa ngakumbi njengoko ubuncinci bobuncinci buncitshisiwe [1]. Nangona kunjalo, i-bandwidth yosuku lwangoku i-selicon-esekwe kwimodyuli ilinganiselwe. I-Silicon ayinayo i-χ (2) -ublineity ngenxa yeseti yawo ye-Creetalline. Ukusetyenziswa kwe-Silicon eqingqiweyo kukhokelele kwiziphumo ezinomdla sele zisele zikho [2], kodwa ukungaziphathi okanye ukungafumani nto kungavumeli izixhobo ezisebenzayo. I-State-ye-Articon Puf Thestoliators ye-Photoniic ke ixhomekeke ekusasazeni i-PNARE-SHINT kwi-PN okanye iPINTUTS [3-5]. I-chancy right cunts ibonisiwe ukuba ibonise imveliso ubude bevolthi njenge-vπl = 0.36 v MM, kodwa isantya semodyuli silinganiselwe ngamandla abathwali abaninzi. Nangona kunjalo, amaxabiso edatha aveliswayo nge-10 GBIT / s avelisiwe ngoncedo logxininiso lombane [4]. Sebenzisa i-cunsols eguqulweyo endaweni yoko, i-bandwidth inyuswe ukuya kwi-30 GHZ [5,6], kodwa i-voltageletlengthy yemveliso yavuka i-vphol = 40 v mm. Ngelishwa, abo banesigaba sesigaba sePlasma semodyuli be-Plasma bavelisa i-Internsity ye-Insoncy engafunekiyo kunye [7], kwaye basabela ngaphandle kwevolli esetyenzisiweyo. Iifomati zemodyuli ezihambele phambili njenge-QAM idinga, nangona kunjalo, i-chardar yendlela yenqanaba kunye nemo esulungekileyo yesigaba, esenza ukuxhaphazwa kwempembelelo ye-elektroniki optic (8]) enqwenelekayo.

I-2. Isondela
Kutshanje, indlela ye-silicon-i-shrid Hybrid (SOH) iphakanyisiwe [9-12]. Umzekelo we-moddulator ye-Soh uboniswe kwi-Fig. 1 (a). Inendawo yokufaka i-slot wavegaide ekhokela intsimi ye-Optical, kwaye imitya emibini ye-silicon edibanisa umbane oqhagamshelo lwe-optical wapho kwii-elektroniki zentsimbi. I-electrode ibekwe ngaphandle kwendawo yemodyuli yokukhanya ukunqanda ilahleko yamehlo [13], fig. 1 (b). Esi sixhobo sidityaniswe kunye ne-ofisi ye-elektroniki optic echanekileyo ehambelana ne-slot. I-vortage yemodyuli yenziwa ngumbane we-metallic waveGuide kwaye ihla kwi-slot enkosi kwimigca ye-silicon esebenzayo. Ibala lombane elikhuthazayo emva koko liyayitshintsha isalathiso sokuvuselelwa kweSlot ngokusebenzisa isiphumo se-Elecro-Optic. Kuba i-slot inobubanzi ngokomyalelo we-100 NM, iivolthi ezimbalwa zanele ukuvelisa amabala okunyanzela okuqinileyo kulungelelwano lwamandla amakhulu. Isakhiwo sinengxaki yokusebenza ephakamileyo ekuseni zombini i-modulation kunye neendawo ezibonakalayo zigxile ngaphakathi kwiSlot, i-1 (b) [14]. Ewe, ukumiliselwa okokuqala kwemodyuli yeSoh enomsebenzi we-vort [11] sele kubonisiwe, kwaye ukuDonuoivesmoid ukuya kuthi ga kwi-40 GHz kwaboniswa [i-15,16]. Nangona kunjalo, umngeni ekwakheni i-vortage ye-SOH ye-SOH ye-Soh ye-Soh ye-SOH ye-SOH yeyokwenza umtya wokudibanisa oqukayo. Kwisekethe elingalinganiyo i-slot inokumelwa yiCapacitor c kunye nemitya eqhubayo ngabaqeqeshwa yi-R, fig. 1 (b). Ixesha le-RC elihambelanayo lihlala libeka i-bandwidth yesixhobo [10,14,14,17,18]. Ukuze kuncitshiswe ukuxhathisa r, kucetyisiwe ukwenza i-doping scris [10,11]. Ngelixa ukusombulula ukunyusa ukuqhubela komzili weSilicon (kwaye ke yonyusa ilahleko yelahleko), enye ihlawula isohlwayo esongeziweyo kuba i-Electron ngenxa yokuba i-Electroning iphazamisekile yingcongconi [10,14,19]. Ngapha koko, ezona mizamo idlulileyo inzalisekisiwe ibonakalise ukuqhekeka kancinci ngokungalindelekanga.

Beijing rofea optoelectilicy Co., i-LTD. I-Clicon Valley "- I-Beijing Zhonghensun, ishishini leTekhnoloji elinikezelweyo, amaziko ophando kunye nabasebenzi bophando lwezenzululwazi. Inkampani yethu isebenzisa uphando oluzimeleyo lophando, uyilo, imveliso, ukuthengisa, ukuthengisa kweemveliso ze-Optoectroalct, kwaye ibonelela ngezisombululo ezinobuchule kunye neenjineli zengcali, kunye neenjineli zemveliso. Emva kweminyaka yokuphucula izinto ezizimeleyo, yenze uthotho olugqibeleleyo nolugqibeleleyo lweemveliso zefotfoletri, ezisetyenziswa ngokubanzi kumasipala, emkhosini, ezomkhosi, ezorhwebo, ezemfundo, ezonyango kunye namanye amashishini.
