He momo noa owhakakaha whatue whakamahia ana i roto i te whakawhitiwhiti kōrero whatu
Ina tukuna ngā tohu whatu i roto i ngā muka whatu, i te mea ka piki haere te tawhiti, ka ngoikore haere ngā tohu whatu, ā, ka raru pea te whakawhitiwhiti kōrero… Kia puta rā anō ngā whakakaha whatu, he rite rātou ki te "teihana penehīni", e whakakī ana i te kaha o ngā tohu whatu kia pai ai te kawe raraunga ki te ūnga. Ma tēnei putanga e whakaatu ki a koe tētahi whakakaha whatu noa i roto i te whakawhitiwhiti kōrero whatu – tewhakakaha muka kua tāpirihia ki te erbium(Whakakaha whatu EDFA).
He whakakaha muka kua tāpirihia ki te erbium, e ai ki te ingoa: Ko te Erbium (Er), he huānga whenua onge, kua whakauruhia ki roto i te muka quartz. Ina haere te tohu whatu whakauru mā roto i te muka kua tāpirihia ki te erbium, ka mimitihia e ngā katote erbium trivalent (Er³⁺) te kaha o te rama papu ka neke ki tētahi taumata kaha teitei ake. Ka hurihia te maha o ngā matūriki i roto i te āhua whakahihiri. I raro i te whakahihiri o te rama tohu whakauru, ka tukuna ngā katote whenua onge āhua whakahihiri, ka tukuna ngā photon o te auau rite ki te rama tohu, ā, ka tutuki te whakahihiri whatu.
Ngā wāhanga e hanga ana i tētahiWhakakaha whatu EDFAKo te nuinga o te wā kei roto ko ngā hononga whatu (he maha ngā wā e whakamahi ana i ngā whakarea wehewehenga roangaru WDM), ngā wehewehe whatu, ngā muka kua tāpirihia ki te erbium, ngā tātari, me ngā pūtake papu. I roto i ēnei, ka whakakotahi te hononga whatu i te mārama whakauru me te mārama papu kia tika ai te werohanga o te tohu ki roto i te muka kua tāpirihia ki te erbium; ko te mahi a te wehewehe whatu ko te pehi i te whakaata mārama koretake i roto i te ara whatu kia kore ai e puta ngā tohu pokanoa koretake, kia tika ai te tuku i te tohu i te taha kotahi; ka tangohia e te tātari whatu te haruru kore e hiahiatia kia pai ake ai te ōwehenga tohu-ki-haruru me te whakarite kia mārama te tuku mōhiohio.
I tēnei wā, kei te whakawhanake ngā kairangahau i ngā whakakaha muka takirua-rohe (DBFA) me ngā whakakaha ultra-whānui (UWOA), e whai ana kia whakawhānui ake i te whānui o te whiwhinga ki te whānui o te roangaru wehenga maha (WDM) katoa. Nō nā tata nei, kua whakawhanakehia e tētahi rōpū rangahau tahi mai i ngā whare rangahau Pākehā tētahi whakakaha ngaru haereere i runga i ngā maramara photonic. Mā te hanganga kiato, ka tutuki i a ia te whakakaha tohu ultra-whānui, me te whānui o te 140 nm (e toru ngā wā o te EDFA tuku iho), ā, kua whakaitihia te rōrahi ki te taumata henimita, e whakarato ana i te tautoko tere-tino mō ngā pokapū raraunga me te rorohiko AI. Ka tautokohia e ēnei "whakakaha tino" te tuku neke atu i te kotahi rau ngā roangaru mō ia muka, e whakatakoto ana i te turanga mō te whakawhitiwhiti kōrero holographic me ngā wheketere atamai me ētahi atu tono i te wā 6G.
