Silicon photonictekinoroji yekutaurirana nedata
Muzvikamu zvakasiyana-siyana zvezvishandiso zvemifananidzo, zvikamu zvesilicon photonic zvinokwikwidzana nemidziyo yepamusoro-soro, iyo inokurukurwa pazasi. Zvichida zvatinoona sebasa rinochinja zvakanyanya mukutaurirana kwemazisondiko kugadzirwa kwemapuratifomu akabatanidzwa anobatanidza ma modulators, ma detectors, ma waveguides, nezvimwe zvikamu pa chip imwe chete zvinotaurirana. Mune zvimwe zviitiko, ma transistors anowanikwawo mumapuratifomu aya, zvichibvumira amplifier, serialization, uye feedback kuti zvese zvibatanidzwe pa chip imwe chete. Nekuda kwemutengo wekugadzira maitiro akadaro, kuedza uku kwakanangana zvakanyanya nemashandisirwo ekutaurirana kwedata pakati pe peer-to-peer. Uye nekuda kwemutengo wekugadzira maitiro ekugadzira transistor, kubvumirana kuri kubuda mumunda ndekwekuti, kubva pamaonero ekushanda uye mutengo, zvine musoro kuti ramangwana rivepo kubatanidza zvishandiso zvemagetsi nekuita tekinoroji yekubatanidza padanho re wafer kana chip.
Pane kukosha kuri pachena mukukwanisa kugadzira machipisi anogona kuverenga uchishandisa michina yemagetsi uye kuita kutaurirana kwemaziso. Mazhinji emashandisirwo ekutanga esilicon photonics aive mukutaurirana kwedata redhijitari. Izvi zvinokonzerwa nemusiyano mukuru wepanyama pakati pemaerekitironi (fermions) nemaphoton (bosons). Maerekitironi akanaka pakuverenga nekuti maviri acho haagone kuva panzvimbo imwe chete panguva imwe chete. Izvi zvinoreva kuti anoshanda nesimba. Saka, zvinokwanisika kushandisa maerekitironi kuvaka zvishandiso zvikuru zvekuchinja zvisina kurongeka - matransistors.
Maphotoni ane hunhu hwakasiyana: maphotoni mazhinji anogona kuva panzvimbo imwe chete panguva imwe chete, uye mumamiriro ezvinhu akasiyana haapindirani. Ndosaka zvichikwanisika kutumira mabhiti edata akawanda pasekondi imwe chete kuburikidza nefiber imwe chete: hazviitwe nekugadzira data stream ine bandwidth imwe chete yeterabit.
Munzvimbo zhinji dzepasi, fiber kuenda kumba ndiyo nzira huru yekuwana data, kunyange hazvo izvi zvisati zvaratidzwa kuti ndezvechokwadi muUnited States, uko inokwikwidzana neDSL nedzimwe tekinoroji. Nekuda kwebandwidth nguva dzose, kudiwa kwekufambisa data kuburikidza nefiber optics kuri kukurawo zvishoma nezvishoma. Mafambiro akafara mumusika wekutaurirana kwedata ndeekuti sezvo daro richiderera, mutengo wechikamu chimwe nechimwe unodzikira zvakanyanya nepo huwandu huchikwira. Hazvishamisi kuti kuedza kwekushambadzira kwesilicon photonics kwave kutarisisa basa rakakura pamashandisirwo epamusoro, mapfupi, nzvimbo dzedata dzakanangana uye computing yepamusoro. Mashandisirwo emangwana anosanganisira board-to-board, USB-scale short-range connectivity, uye pamwe kunyange CPU core-to-core communication pakupedzisira, kunyangwe zvichaitika nemashandisirwo epakati-to-core pachip zvichiri kufungidzira. Kunyangwe zvisati zvasvika padanho reindasitiri yeCMOS, silicon photonics yatanga kuva indasitiri yakakosha.
