Photonics Silicon Ikintu gikora

Photonike Ibigize IBIKORWA Bivuga byumwihariko kugirango imikoranire yateguwe nkana hagati yumucyo nikibazo. Ikintu gisanzwe gikora cya fotosics ni modulator nziza. Byose Byuzuye SiliconModulator ya Optiquebashingiye ku ngaruka za Plasma kubuntu. Guhindura umubare wa electron yubusa nimwobo mubikoresho bya silicon kubikoresho, amashanyarazi cyangwa optique yerekanwe mubipimo bihuye na soref na bennett kumurongo wa Nanometero 150. Ugereranije na electron, umwobo utera uruhara runini rwimyandikire nyayo kandi yibitekerezo bihinduka, nibyo, birashobora gutanga ibyiciro binini byicyiciro cyatewe nigihome cyatanzwe, reroMach-Zehnder Modulatorna modulator, mubisanzwe ihitamo gukoresha umwobo kugirango ukoreAbanyeshuri ba Para.

IbinyuranyeSilicon (Si) ModulatorUbwoko bwerekanwe ku gishushanyo cya 10a. Muri Modulator yashishikarije, urumuri ruherereye muri siliconi yitegereza cyane muri pinte yagutse cyane, na electron nimwobo. Ariko, modulatosizi iratinda, mubisanzwe hamwe numurongo wa 500 mhz, kuko electron yubusa nimwobo zifata igihe kinini kugirango usubiremo nyuma yo gutera inshinge. Kubwibyo, iyi miterere ikunze gukoreshwa nkumuntu uhinduka Opteuator (VOA) aho kuba Modulator. Muri Modulator yo guhungabanya umutekano, umugabane wicyo uherereye muri PN Ihuriro rito rya PN, kandi ubugari bwo guhunga bwa PN bwahinduwe numurima w'amashanyarazi. Iyi Modutor irashobora gukora ku muvuduko urenze 50GB / s, ariko ifite igihombo kinini cyo kwinjiza. Vpil isanzwe ni 2 v-cm. Icyuma cya Oxide Semiconductor (Mos) (mubyukuri semiconductor-oxide-semickonductor) modulator irimo urwego ruto ruto muri pn ihuriro rya PN. Iyemerera kwigarurira abatwara kimwe no kugabanuka, kwemerera v0l ntoya ya 0.2 V-cm, ariko ifite ibishoboka byose igihombo cyo hejuru cya optique hamwe nubushobozi bwo murwego rwo hejuru. Byongeye kandi, hari aho bahuza amashanyarazi ashingiye kuri Sige (Silicon Genium Morloy) Urugendo rwa Band Edge. Mubyongeyeho, hari modulatori ya Gradulator ishingiye kuri graphene kugirango ihindure imiyoboro ikurura ibyuma hamwe na sudulatickers. Ibi byerekana uburyo butandukanye bwo gusaba uburyo butandukanye kugirango ugere kumuvuduko mwinshi, igihombo gito cya Optique.

Igicapo 10: (a) Igishushanyo-gishushanyo mbonera cyibishushanyo mbonera bishingiye kuri shidulator ya silicon. B) Igishushanyo cyambukiranya igice cyibishushanyo mbonera.

Ibibaho byinshi bishingiye kuri silicon bigaragarira ku gishushanyo cya 10b. Ibikoresho bikurura ni ikidage (ge). GE ishoboye gukuramo urumuri ku burebure bugera kuri microne 1.6. Yerekanwe ibumoso nuburyo bwiza bwa PIN iki gihe. Igizwe nubwoko bwa P-Ubwoko bwa Silicon kuri gene ikura. GE na si bafite 4% bidahuye, kandi kugirango ugabanye imyigishiriri, urwego ruto rwa sige rwabanje gukura nkurwego rwa buffer. N-Andika doping ikorwa hejuru ya ge layer. Icyuma-semiconductor-ibyuma (MSM) Photodiode yerekanwe hagati, hamwe na APD (Avalanche Photodetetector) irerekanwa iburyo. Agace ka Avalanche muri APD iherereye muri si, ifite ibiranga urusaku byo hasi ugereranije n'akarere ka Avalanche mu itsinda rya III-v ibikoresho bikomeye.

Kugeza ubu, nta gisubizo gifite inyungu zigaragara muguhuza inyungu za optique hamwe na fonesics silicon. Igishushanyo cya 11 cyerekana uburyo bwinshi bushoboka bwateguwe nurwego rwinteko. Kubumoso bwa kure ni ubufatanye bwa monolithic birimo gukoresha Eptaxic robite yubudage (ge) nkibikoresho byiza. Nka al2o3, hamwe na EPITO3 Inkingi ikurikira ni wafer mu nteko ya Wafer, irimo okiside no guhuza kama mukarere ka III-v. Inkingi ikurikira ni Inteko ya Chip-Uwafer, ikubiyemo kwinjiza itsinda rya III-v mu mwobo wa silicon wafer hanyuma ukariha imiterere ya Waveguide. Inyungu yiyi mitwe itatu yambere yinkingi nuko igikoresho gishobora kuba gikora neza imbere muri Wafer mbere yo guca. Inkingi iburyo ni Inkomoko ya Chip-To-Chip, harimo guhuza amacakubiri ya silicon kuri chip ya III-v V. Icyerekezo cyo gusaba ubucuruzi kiva iburyo kugera ibumoso bwimbonerahamwe yerekeza kubisubizo byinjijwe kandi ihujwe.

Igishushanyo 11: Ukuntu inyungu zoroshye zihujwe muri photonic ishingiye kuri silicon. Mugihe wimuka uva ibumoso ugana iburyo, gufatanya kwinjiza buhoro buhoro buhoro buhoro buhoro.
