Kimwe mu bintu by'ingenzi bya modulator ya optique ni umuvuduko wacyo cyangwa umurongo, ugomba kuba byibuze byihuse nka elegitoroniki iboneka. Abacukuzi bafite imirongo yo gutambuka hejuru ya 100 GHz bamaze kugaragara muri tekinoroji ya 90 ya NM muri Silicon, kandi umuvuduko uzarushaho kwiyongera nkimiterere ntarengwa yagabanutse [1]. Ariko, umurongo wa modulatori ya silicon muri iki gihe ikorera muri iki gihe ni make. Silicon ntabwo afite χ (2) -Nkunlinearity bitewe na centro-symmetric stracet. Gukoresha silicon igororotse byatumye ibisubizo bishimishije bimaze [2], ariko kutabagirana ntibigera kwemerera ibikoresho bifatika. Leta-ya-Art Sitelic Modulator ya Photonic iracyashingira kuri Disirity Gutatana muri PN cyangwa PIN (3-5]. IHINDURE Ihumure ryo kubogama ryagaragaye kugirango rigaragaze ibicuruzwa bya volut. Nubwo bimeze bityo, ibipimo byamakuru bya 10 Gut / s byatanzwe hifashishijwe mbere yikimenyetso cyamashanyarazi [4]. Ukoresheje imiryango ibogamye ibogamye aho, umugwani yiyongereyeho nka 30 GHz [5,6], ariko ibikoresho bikomeye bya voltagele byazamutse kuri v0l = 40 v mm. Kubwamahirwe, ingaruka nkizo modulator zitanga ubukana utifuzwa na hamwe [7], kandi basubiza tutari mumagambo yakoreshejwe. Ikirangantego cyateye imbere nka QAM isaba, ariko, igisubizo cyumurongo hamwe nicyiciro cyapa, bigakora ingaruka za electro-optic (8]) cyane.

Vuba aha, Silicon-Orbrid Hybrid (Soh) uburyo bwatanzwe [9-12]. Urugero rwa modutor ya soh irerekanwa ku gishushanyo 1 (a). Igizwe n'umwanya wa Wavegue uyobora umurima mwiza, hamwe na silicon ebyiri za silicon zihuza amashanyarazi ya optique kuri electrode metallic. Electrode iherereye hanze yumurima wa optique kugirango wirinde igihombo cya optique [13], Ishusho 1 (b). Igikoresho cyashizwemo ibikoresho bya electro-optique biranga kimwe cyuzuyemo urupapuro. Imyitwarire ya modulating itwarwa na Metallic Amashanyarazi hanyuma agabanuka hirya no hino arashimira imirongo ya silicon igenda. Umurima w'amashanyarazi wavuyemo hanyuma uhindure indangagaciro yo gutunganya mumwanya unyuze mu ntsinzi ya electro-yihuta. Kubera ko ikibanza gifite ubugari muri gahunda ya NM 100, hurika nkeya zirahagije kugirango utange imirima ikomeye ya modulating iringaniza iringaniza ryinshi ryimbaraga zimirire y'ibikoresho byubusa. Imiterere ifite uburyo bworoshye bwo gukora neza kuva modulating hamwe nimirima ya optique yibanze mumwanya, ishusho 1 (b) [14]. Mubyukuri, gushyira mubikorwa byambere bya modulators hamwe nibikorwa byo munsi yisumbuye [11] byaragaragaye, kandi byahinduye Sinusoidal kugeza 40 GHZ yerekanwe [15,16]. Ariko, ikibazo cyo kubaka voltage-voltage yihuta cyane soh modulator ni ugukora umurongo uhuza neza. Mubikorwa bihwanye nabyo birashobora guhagararirwa na capainer c hamwe nimirongo itwara abagurisha r, fig. 1 (b). Igihe cya RC gihuye kigena umurongo wagataguro wibikoresho [10,14,17,18]. Mu rwego rwo kugabanya kurwanya r, byasabwe gukora imirongo ya silicon [10,14]. Mugihe icyogajuru cyongera imirongo ya silicon (bityo rero yongera igihombo cya optique), umuntu yishyura igihombo cyinyongera kuko kugenda kwa elegitoroniki yangirika kwanduye [10,14,19]. Byongeye kandi, kugerageza guhimba ibihimbano byagaragaye ko bitunguranye.
LTDING ROFONEA Optoelectronics Co., Ltd. Ikibaya cya Silicon "- ni ikigo cy'ikoranabuhanga mu bushinwa cyahariwe gukorera ibigo by'ubushakashatsi mu gihugu. Isosiyete yacu ikorwa ahanini ubushakashatsi niterambere ryigenga niterambere, igishushanyo, inganda, kugurisha ibicuruzwa bya optoelectronic, kandi bitanga ibisubizo bishya, byihariye kubashakashatsi bahangana na ba injeniyeri. Nyuma yimyaka myinshi yo guhanga udushya, yashinze urukurikirane rwibicuruzwa bikungahaye kandi byuzuye bikoreshwa cyane mu komini, igisirikare, ubwikorezi, ubuhinzi bwamashanyarazi, ubuvuzi, ubuvuzi nizindi nganda.
