Pamene njira ya chip ikuchepa pang'onopang'ono, zotsatira zosiyanasiyana zomwe zimayambitsidwa ndi cholumikiziracho zimakhala chinthu chofunikira kwambiri chomwe chimakhudza magwiridwe antchito a chip. Kulumikizana kwa chip ndi chimodzi mwazopinga zamakono zomwe zikuchitika, ndipo ukadaulo wa optoelectronics wochokera ku silicon ukhoza kuthetsa vutoli. Ukadaulo wa Silicon photonic ndi njira yothandiza kwambiri.kulankhulana kwa kuwalaukadaulo womwe umagwiritsa ntchito kuwala kwa laser m'malo mwa chizindikiro cha semiconductor chamagetsi potumiza deta. Ndi ukadaulo wa m'badwo watsopano wozikidwa pa zinthu za silicon ndi silicon ndipo umagwiritsa ntchito njira ya CMOS yomwe ilipo kalechipangizo chowunikirachitukuko ndi kuphatikiza. Ubwino wake waukulu ndi wakuti uli ndi liwiro lalikulu kwambiri lotumizira deta, zomwe zingapangitse liwiro lotumizira deta pakati pa ma processor cores kukhala lachangu nthawi 100 kapena kuposerapo, ndipo mphamvu yamagetsi nayonso ndi yapamwamba kwambiri, kotero imaonedwa kuti ndi mbadwo watsopano wa ukadaulo wa semiconductor.
M'mbuyomu, ma silicon photonics adapangidwa pa SOI, koma ma SOI wafers ndi okwera mtengo ndipo sizinthu zabwino kwambiri pa ntchito zosiyanasiyana za ma photonics. Nthawi yomweyo, pamene kuchuluka kwa deta kukukwera, kusintha kwa liwiro la zinthu za silicon kukukhala vuto lalikulu, kotero zinthu zatsopano zosiyanasiyana monga mafilimu a LNO, InP, BTO, ma polima ndi zinthu za plasma zapangidwa kuti zigwire bwino ntchito.
Kuthekera kwakukulu kwa silicon photonics kuli pophatikiza ntchito zingapo mu phukusi limodzi ndikupanga zambiri kapena zonse, monga gawo la chip chimodzi kapena mulu wa tchipisi, pogwiritsa ntchito zipangizo zomwezo zomwe zimagwiritsidwa ntchito popanga zipangizo zamakono zamakono (onani Chithunzi 3). Kuchita izi kudzachepetsa kwambiri mtengo wotumizira deta paulusi wa kuwalandikupanga mwayi wa mitundu yosiyanasiyana ya mapulogalamu atsopano muzithunzi, zomwe zimathandiza kuti pakhale njira zovuta kwambiri zomangira makina pamtengo wotsika kwambiri.
Mapulogalamu ambiri akubwera pamakina ovuta a silicon photonic, omwe nthawi zambiri amakhala mauthenga a data. Izi zikuphatikizapo mauthenga a digito okhala ndi bandwidth yayikulu pamapulogalamu afupiafupi, njira zovuta zosinthira ma modulation pamapulogalamu akutali, komanso mauthenga ogwirizana. Kuphatikiza pa kulumikizana kwa data, ntchito zambiri zatsopano zaukadaulo uwu zikufufuzidwa m'mabizinesi ndi m'masukulu. Mapulogalamu awa akuphatikizapo: Nanophotonics (nano opto-mechanics) ndi condensed matter physics, biosensing, nonlinear optics, LiDAR systems, optical gyroscopes, RF integratedzamagetsi a opto, ma transceivers a wailesi ophatikizidwa, kulumikizana kogwirizana, zatsopanomagwero a kuwala, kuchepetsa phokoso la laser, masensa a gasi, ma photonics olumikizidwa ndi mafunde aatali kwambiri, kukonza ma signal mwachangu komanso mwachangu mu microwave, ndi zina zotero. Madera abwino kwambiri ndi monga biosensing, imaging, lidar, inertial sensing, hybrid photonic-radio frequency integrated circuits (RFics), ndi signal processing.
