Silicon Photonic Data Communication Technology

Zithunzi za siliconukadaulo wolumikizana ndi data
M'magulu angapo azipangizo zamakono, zigawo za silicon photonic zimapikisana ndi zipangizo zamakono, zomwe zikukambidwa pansipa. Mwina chomwe timachiwona ngati ntchito yosintha kwambirioptical kulankhulanandikupangidwa kwa nsanja zophatikizika zomwe zimaphatikiza ma modulators, zowunikira, ma waveguides, ndi zida zina pa chip chomwechi chomwe chimalumikizana wina ndi mnzake. Nthawi zina, ma transistors amaphatikizidwanso m'mapulatifomuwa, kulola kuti amplifier, serialization, ndi mayankho onse aziphatikizidwa pa chip chomwecho. Chifukwa cha mtengo wopangira njira zotere, kuyesayesa kumeneku kumayang'ana kwambiri pakugwiritsa ntchito kulumikizana kwa data ndi anzawo. Ndipo chifukwa cha mtengo wopangira njira yopangira ma transistor, mgwirizano womwe ukubwera m'mundawu ndikuti, kuchokera ku magwiridwe antchito ndi momwe amawonera mtengo, zimakhala zomveka kuti tsogolo lodziwikiratu liphatikize zida zamagetsi popanga ukadaulo wolumikizira pa chowotcha kapena chip. mlingo.

Pali phindu lodziwikiratu pakutha kupanga tchipisi totha kuwerengera pogwiritsa ntchito zida zamagetsi ndikuchita kulumikizana ndi kuwala. Zambiri mwazogwiritsidwa ntchito koyambirira kwa ma silicon photonics zinali mu kulumikizana kwa digito. Izi zimayendetsedwa ndi kusiyana kwakukulu pakati pa ma elekitironi (fermions) ndi ma photons (ma bosons). Ma electron ndi abwino pakompyuta chifukwa awiriwa sangakhale pamalo amodzi nthawi imodzi. Izi zikutanthauza kuti amalumikizana mwamphamvu wina ndi mnzake. Choncho, n'zotheka kugwiritsa ntchito ma elekitironi kuti apange zipangizo zazikulu zosinthira zopanda mzere - transistors.

Zithunzi zimakhala ndi katundu wosiyana: zithunzi zambiri zimatha kukhala pamalo amodzi nthawi imodzi, ndipo pazochitika zapadera sizimasokonezana. Ichi ndichifukwa chake ndizotheka kufalitsa ma thililiyoni a data pa sekondi imodzi kudzera mu ulusi umodzi: sizimachitidwa popanga mtsinje wa data ndi terabit bandwidth imodzi.

M'madera ambiri a dziko lapansi, ulusi wopita kunyumba ndiye njira yayikulu yofikira, ngakhale izi sizinatsimikizidwe kuti ndi zoona ku United States, komwe zimapikisana ndi DSL ndi matekinoloje ena. Ndi kufunikira kosalekeza kwa bandwidth, kufunikira koyendetsa kufalitsa kowonjezereka kwa deta kudzera mu fiber optics kukukulanso mosalekeza. Njira yotakata pamsika yolumikizirana ndi data ndikuti pomwe mtunda ukuchepa, mtengo wagawo lililonse umatsika kwambiri pomwe voliyumu ikuwonjezeka. N'zosadabwitsa kuti zoyesayesa zamalonda za silicon photonics zakhala zikuyang'ana ntchito yochuluka kwambiri, ntchito zazifupi, zowunikira malo opangira deta ndi makompyuta apamwamba kwambiri. Mapulogalamu amtsogolo adzaphatikizapo bolodi-to-board, kulumikizana kwaufupi kwa USB, ndipo mwinanso kulumikizana kwapakati pa CPU pamapeto pake, ngakhale zomwe zingachitike ndikugwiritsa ntchito pa chip pa chip zikadali zongopeka. Ngakhale sichinafike pamlingo wamakampani a CMOS, ma silicon photonics ayamba kukhala bizinesi yayikulu.
