Ngā Taupānga Hou oPūoko Whakaahua Tere-Tiketike
He mārama, he kanapa rawa, ā, tata kore e kitea, engari koia te mea e whakatau ana i te tere o te whakawhitiwhiti kōrero ā muri ake nei… I te ao gigabit e rere ana ngā tohu mārama ki ngā wāhi katoa, ko ia nanohekona o te whakaroa ka tohu pea i te ngaronga o ngā raraunga nui. Te kimi i te tere o te mārama, ngā pūnaha whakawhitiwhiti kōrero 43Gbit/s, ngā hononga photonic ngaruiti… Kei te pātai tonu ēnei mara hou: He kaupapa kimi optoelectronic e whakakotahi ana i te aro nui me te urupare tere rawa?
I ēnei rā, ko te raupapa ROF-PT o ngā oro whakakaha tere-teiteipūoko whakaahuaKua whakaratohia e ngā kōwae he whakautu mārama, he whakautu whakatau hoki.
Mā te whakauru hōhonu i te tere teiteiNgā pūoko PINMā te whakamahi i ngā maramara whakakaha TIA tino tika, kua hangaia e mātou he hononga arotau tohu katoa mai i te whakaurunga ki te putanga. Mā te hononga muka aratau-kotahi ka whakarite kia parakore te whakaurunga tohu, ka tutuki i ngā hononga K te putanga pumau me te whai hua, ā, mā te whānui o te whānuitanga tae atu ki te 40GHz me te wā urupare iti iho i te 10ps ka kore e taea te huna i te ara o te tohu whatu. Ahakoa ko te hopu whānui o te whānuitanga hihi 1200-1650nm, ko te taurite rānei o te whakanui teitei, te aro nui me te papatahi o te whakanui, ka whai tonu te raupapa ROF-PT ki te whakatutuki i te taurite huatau i waenga i te tere me te tika.
Ahakoa ngā whakaritenga tino pakari o te pūnaha hononga ngaruiti ROF, te wero rānei o ngā tohu ngoikore i roto i te pūoko Brillouin, ka taea hoki e ia te tautoko i te putanga rerekētanga ritenga, ka taea ai te whakauru ngāwari ki roto i tō hoahoa pūnaha teitei.
Ko te whakanui hihi tere-teitei raupapa ROF-PTpūoko hiko whakaahuaKa tukuna e te kōwae he otinga whai hua ake, he pono ake hoki ki ngā kaihangarau, kia taea ai e rātou te whakahaere i ngā mahi uaua ki te kimi tohu mārama me te marino me te maia ake. Ehara tēnei i te kōwae noa iho; koia hoki te tūāpapa mahi mō ngā tono hangarau whatu ā muri ake nei – i konei, ka hopukina tika te ara mārama, ā, ka tautuhia ngātahitia te tere e mātou.
