A cikin nau'ikan nau'ikanna'urorin daukar hoto, Abubuwan da aka gyara na silicon photonic suna gasa tare da na'urori masu kyau a cikin aji, waɗanda aka tattauna a ƙasa. Wataƙila abin da muke ɗauka shine aikin da ya fi canzawa a cikisadarwa na ganishine ƙirƙirar dandamali masu haɗaka waɗanda ke haɗa na'urori masu daidaitawa, na'urorin ganowa, waveguides, da sauran abubuwan haɗin gwiwa akan guntu ɗaya waɗanda ke sadarwa da juna. A wasu lokuta, transistor kuma ana haɗa su a cikin waɗannan dandamali, yana ba da damar haɓakawa, serialization, da martani ga duka akan guntu ɗaya. Saboda tsadar haɓaka irin waɗannan hanyoyin, wannan ƙoƙarin yana da niyya da farko ga aikace-aikace don sadarwar bayanan ɗan adam-da-tsara.

Akwai fa'ida a bayyane cikin samun damar yin kwakwalwan kwamfuta waɗanda za su iya ƙididdigewa ta amfani da na'urorin lantarki da aiwatar da sadarwar gani. Yawancin aikace-aikacen farko na silicon photonics sun kasance a cikin sadarwar bayanan dijital. Wannan yana haifar da ainihin bambance-bambancen jiki tsakanin electrons (fermions) da photons (bosons). Electrons suna da kyau don yin lissafi saboda su biyun ba za su iya zama wuri ɗaya a lokaci ɗaya ba. Wannan yana nufin suna mu'amala mai ƙarfi da juna. Sabili da haka, yana yiwuwa a yi amfani da electrons don gina manyan na'urori masu sauyawa marasa daidaituwa - transistor.

Photons suna da kaddarorin daban-daban: yawancin photons na iya kasancewa a wuri ɗaya a lokaci guda, kuma a cikin yanayi na musamman ba sa tsoma baki tare da juna. Shi ya sa yana yiwuwa a iya watsa tiriliyan na bayanai a cikin daƙiƙa guda ta hanyar fiber guda: ba a yin hakan ta hanyar ƙirƙirar rafin bayanai tare da bandwidth guda ɗaya.
