Te whakataurite i ngā pūnaha rauemi ara iahiko whakauru photonic
E whakaatu ana te Pikitia 1 i tētahi whakataurite o ngā pūnaha rauemi e rua, te indium Phosphorus (InP) me te silicon (Si). Nā te onge o te indium ka nui ake te utu o te InP i te Si. Nā te mea he iti ake te tipu epitaxial o ngā ara iahiko e ahu mai ana i te silicon, he nui ake te hua o ngā ara iahiko e ahu mai ana i te silicon i ērā o ngā ara iahiko InP. I roto i ngā ara iahiko e ahu mai ana i te silicon, ko te germanium (Ge), e whakamahia ana i roto iPūoko Whakaahua(ngā pūoko mārama), me tupu te epitaxial, i roto i ngā pūnaha InP, me whakarite ngā arataki ngaru kore mahi mā te tupu epitaxial. Ko te tipu epitaxial he nui ake te kiato hapa i te tupu tioata kotahi, pērā i te mea mai i te ingot tioata. He teitei te rerekētanga o te taupū whakaata o ngā arataki ngaru InP i te whakawhiti anake, ko ngā arataki ngaru e hangai ana ki te silicon he teitei te rerekētanga o te taupū whakaata i te whakawhiti me te roa, e āhei ai ngā taputapu e hangai ana ki te silicon ki te whakatutuki i ngā radius piko iti ake me ētahi atu hanganga kiato ake. He āputa roopu tika tō te InGaAsP, engari kāore a Si me Ge. Nō reira, he pai ake ngā pūnaha rauemi InP i runga i te whai huatanga o te laser. Kāore ngā waikura ā-roto o ngā pūnaha InP i te pumau me te pakari pērā i ngā waikura ā-roto o te Si, te hauhā silicon (SiO2). He rauemi kaha ake te silicon i te InP, e āhei ai te whakamahi i ngā rahi wafer nui ake, arā, mai i te 300 mm (ka whakahoutia wawe ki te 450 mm) ki te whakaritea ki te 75 mm i roto i te InP. InPngā kaiwhakarerekēi te nuinga o te wā ka whakawhirinaki ki te pānga Stark e herea ana e te matū, he mea tairongo ki te pāmahana nā te nekehanga o te taha o te whitiki i puta mai i te pāmahana. He rerekē, he iti noa te whakawhirinakitanga o te pāmahana o ngā kaiwhakatikatika e hangai ana ki te silicon.

Ko te hangarau hāora hiko e whakaarohia ana he pai anake mō ngā hua iti te utu, poto te tawhiti, nui te rahinga (neke atu i te 1 miriona ngā wahi ia tau). Nā te mea e whakaaetia whānuitia ana he nui te kaha o te wafer e hiahiatia ana hei tohatoha i ngā utu mō te kopare me te whanaketanga, ā,hangarau whakaahua siliconhe nui ngā ngoikoretanga o te mahi i roto i ngā tono hua mai i te tāone ki te tāone, ā-rohe, me te tawhiti. Heoi, ko te mea pono, ko te ritenga kē. I roto i ngā tono iti te utu, poto te tawhiti, nui te hua, ko te taiaho tuku mata kōhao poutū (VCSEL) mete taiaho whakatikatika-tika (Taiaho DML) : he nui te pēhanga whakataetae o te reera whakarerekētia tika, ā, ko te ngoikore o te hangarau photonic e hangai ana ki te silicon e kore e taea te whakauru ngāwari i ngā reera kua waiho hei ngoikoretanga nui. He rerekē, i roto i ngā tono metro, tawhiti, nā te pai ki te whakauru i te hangarau photonics silicon me te tukatuka tohu mamati (DSP) (he maha ngā wā i roto i ngā taiao pāmahana teitei), he pai ake te wehe i te reera. Hei tāpiri, ka taea e te hangarau kitenga honohono te whakakī i ngā ngoikoretanga o te hangarau photonics silicon ki te whānuitanga nui, pēnei i te raruraru he iti ake te ia pōuri i te ia whakaahua oscillator ā-rohe. I taua wā anō, he hē hoki te whakaaro he nui te kaha o te wafer e hiahiatia ana hei utu i ngā utu kopare me te whanaketanga, nā te mea ka whakamahia e te hangarau photonics silicon ngā rahi pona he nui ake i ngā semiconductors waikura whakarewa tino matatau (CMOS), nō reira he iti te utu o ngā kopare me ngā oma whakaputa e hiahiatia ana.
