Ngā tūemi matua opūoko whakaahuawhakamātautau
Ko te whānui me te wā piki (e mōhiotia ana ko te wā urupare) o ngā taputapu whakaahua, hei mea matua i roto i te whakamātautau i ngā taputapu whakaahua, kua arohia e te tini o ngā kairangahau optoelectronic. Heoi, kua kitea e te kaituhi he tokomaha te hunga kāore i te mārama ki ēnei tawhā e rua. I tēnei rā, ka whakamōhio motuhake a JIMu Optoresearch i te whānui me te wā piki o ngā taputapu whakaahua ki te katoa.
I roto i te tuhinga o mua mō te kōwhiringa o ngā tawhā matua mōngā diode whakaahua, i whakaurua e mātou ko te wā piki (τr) me te wā hinga (τf) he tohu matua mō te ine i te tere urupare o ngā taputapu whakaahua. Ko te whānui o te 3dB, hei tohu i roto i te rohe auau, he hononga tata ki te wā piki e pā ana ki te tere urupare. Ko te whanaungatanga i waenga i te whānui o te BW o te taputapu whakaahua me tōna wā urupare Tr ka taea te huri mā te tātai e whai ake nei: Tr=0.35/BW.
Ko te wā piki he kupu i roto i te hangarau pāorooro, e whakaahua ana, e tohu ana hoki i te pikinga o te tohu mai i tētahi pūwāhi (te tikanga: Vout*10%) ki tētahi atu pūwāhi (te tikanga: Vout*90%). Ko te kaha o te taha piki o te tohu Wā Piki e pā ana ki te wā e pau ana ki te pikinga mai i te 10% ki te 90%. Mātāpono whakamātautau: Ka tukuna te tohu i runga i tētahi ara, ā, ka whakamahia tētahi atu pane tauira hei tiki me te ine i te uara pāorooro ngaohiko i te pito tawhiti.
He mea nui te wā piki o te tohu hei mārama ki ngā take o te pono o te tohu. Ko te nuinga o ngā raruraru e pā ana ki te mahi a te tono hua i roto i te hoahoa opūoko whakaahua tere-teiteie pā ana ki tēnei. I te wā e whiriwhiri ana i tētahi taputapu whakaahua, me aro nui koe ki tēnei. He mea nui kia whakatūria e tātou te ariā he pānga nui te wā piki ki te mahi a te ara iahiko. Mena kei roto i tētahi whānuitanga, me tino aro atu ki tēnei, ahakoa he whānuitanga tino pōuri. Kāore he take ki te tautuhi tika i tēnei paerewa whānuitanga, kāore hoki he hiranga mahi. Kia mahara noa kua poto rawa tēnei wā nā te hangarau tukatuka maramara o nāianei, ā, kua tae ki te taumata ps. Kua tae ki te wā kia aro nui koe ki tōna pānga.
I te hekenga o te wā pikinga o te tohu, ka nui haere ngā raruraru pēnei i te whakaata, te whakawhitiwhiti kōrero, te hinganga o te porowhita, te irahiko hikohiko, me te peke whenua i puta mai i te tohu ā-roto, i te tohu putanga rānei o te taputapu whakaahua, ā, ka uaua ake te whakaoti i te raruraru haruru. Mai i te tirohanga a te tātaritanga hihi, ko te whakaiti i te wā pikinga o te tohu he rite ki te pikinga o te whānui o te tohu, arā, he nui ake ngā wāhanga auau-teitei i roto i te tohu. Ko ēnei wāhanga auau-teitei tonu te mea e uaua ai te hoahoa. Me whakaaro ngā raina hononga ki ngā raina tuku, ā, kua hua ake he maha ngā raruraru kāore i mua.
Nō reira, i roto i te tukanga tono o ngā taputapu whakaahua, me whai whakaaro pēnei koe: ina he pikinga teitei te tohu putanga o te taputapu whakaahua, he nui rawa rānei te rahinga, ā, he kore pumau te tohu, he tino tūponotanga kāore te taputapu whakaahua i hokona e koe e tutuki i ngā whakaritenga hoahoa e tika ana mō te pono o te tohu, ā, kāore e taea te whakatutuki i ō whakaritenga tono tuturu e pā ana ki te whānui me ngā tawhā wā piki. Ko ngā hua taputapu whakaahua hiko o JIMU Guangyan katoa e whakaatu ana i ngā maramara whakaahua hiko matatau hou, ngā maramara whakakaha whakahaere tere-teitei, me ngā ara iahiko tātari tika. E ai ki ngā āhuatanga tohu tono tuturu a ngā kiritaki, ka ōrite te whānui me te wā piki. Ka whakaarohia e ia taahiraa te pono o te tohu. Āta karohia ngā raruraru noa pēnei i te haruru tohu nui me te pumau ngoikore i puta mai i te kore taurite i waenga i te whānui me te wā piki i roto i te tono o ngā taputapu whakaahua ki ngā kaiwhakamahi.
