Ukuqhathaniswa kwezinhlelo zezinto ezihlanganisiwe ze-Photonic ezihlanganisiwe
Umdwebo 1 ukhombisa ukuqhathanisa kwezinhlelo ezimbili ezibonakalayo, i-Indium phosphorus (inp) ne-silicon (SI). Ukuvuselelwa kwe-Indium kwenza i-inp i-inc kubiza kakhulu ukwedlula i-SI. Ngenxa yokuthi amasekhethi asuselwa ku-silicon afaka ukukhula okuncane kwe-Epitaxial, isivuno semijikelezo esekwe ku-silicon imvamisa iphakeme kunaleyo yemibuthano ye-INP. Emibuthanweni esekwe ku-silicon, i-germanium (ge), evame ukusetshenziswa kuphela ngaphakathiI-PhotoDETETETETECETETET(Imitshizo elula), kudinga ukukhula kwe-epitaxial, ngenkathi kusezinhlelweni ze-INP, ngisho nama-wavegcuides angabonakali kufanele alungiswe ngokukhula kwe-Epitaxial. Ukukhula kwe-EpiTaxial kuvame ukuba nesici esinamandla esiphakeme kunokukhula okukodwa kwe-crystal, njengokuvela ku-ingot yekristalu. I-INP WaveGuides inezinkomba eziphakeme kakhulu ze-reuntud ihlukahlukana kuphela, kanti ama-waveguides asuselwa ku-silicon anezinkomba eziphakeme kakhulu kuhluke kakhulu ku-transverse futhi ende, evumela amadivaysi asuselwa ku-silicon ukufeza i-radii emincane yokugoba nezinye izinhlaka ezihlangene. I-Ingaas inegebe eliqondile le-band, ngenkathi kufanele Ngenxa yalokho, izinhlelo ze-INP ezibonakalayo ziphakeme ngokwemigomo yokusebenza kahle kwe-laser. I-oxides engaphakathi kwezinhlelo ze-INP ayizinzile futhi iqine njengezinto ezingaphakathi ze-oxides ze-SI, i-silicon dioxide (Sio2). I-Silicon iyinto enamandla kakhulu kune-INP, ivumela ukusetshenziswa kosayizi abakhulu be-wafer, okungukuthi kusuka ngo-300 mm (kungekudala ukuze kuthuthukiswe ku-450 mm) kuqhathaniswe no-75 mm ku-INP. Inhleloama-modulatorsImvamisa incike emqhumeni we-quantum-eboshiwe, okuzwela izinga lokushisa ngenxa yokunyakaza kwe-band emaphethelweni okubangelwa izinga lokushisa. Ngokuphambene, ukuncika kokushisa kwama-modulators asuselwa ku-silicon kuncane kakhulu.

I-Silicon Photonics Technology icatshangelwa kuphela ilungele izindleko eziphansi, ibanga elifushane, imikhiqizo ephezulu yevolumu (izingcezu ezingaphezu kwezigidi eziyi-1 ngonyaka). Lokhu kungenxa yokuthi kwamukelwa kabanzi ukuthi inani elikhulu lomthamo okhalweni liyadingeka ukusabalalisa imaski nezindleko zokuthuthuka, nokuthiI-Silicon Photonics TechnologyInobunzima obukhulu bokusebenza ekusebenzeni kwezicelo zoMkhiqizo weCity-to-City kanye ne-Long-Haul Product. Eqinisweni, noma kunjalo, okuphambene nalokho kuyiqiniso. Ngezindleko eziphansi, ububanzi obufushane, izinhlelo eziphezulu zesivuno, i-vertical cavity surving i-laser (VCSEL) neI-laser eqondiswe ngqo (I-DML Laser): I-laser elungiswe ngokuqondile ibeka ingcindezi enkulu yokuncintisana, kanye nobuthakathaka bobuchwepheshe obusekelwe eSilicon Photonic abakwazi ukuhlanganisa ama-lasers kalula abe yingozi ebalulekile. Ngokuphambene nalokho, ku-metro, izinhlelo ezinde zebanga, ngenxa yokuthanda kokuhlanganisa ubuchwepheshe be-silicon Photonics kanye nokusebenza kwesiginali yedijithali (DSP) ndawonye (okuvame ukuba sendaweni ephezulu yokushisa), kunenzuzo enkulu yokuhlukanisa i-laser. Ngaphezu kwalokho, ubuchwepheshe bokuthola ukubumbana bungakha amaphutha obuchwepheshe be-silicon Photonics ngezinga elikhulu, njengenkinga yokuthi amanje amnyama mancane kakhulu kune-Oscillator yendawo. Ngasikhathi sinye, futhi akulungile ukucabanga ukuthi inani elikhulu lobuthakathi okhalweni liyadingeka ukumboza ama-mask kanye nezindleko zokuthuthuka, ngoba ubuchwepheshe be-silicon Photonics busebenzisa ama-semivuctuctors wensimbi athuthuke kakhulu (ama-CMOs), ngakho-ke ama-masks adingekayo ashibhile.
