Ko ngā whatu whakauru he kaupapa hou e ako ana, e whakawhanake ana hoki i ngā taputapu whatu me ngā pūnaha taputapu hiko whatu ranu mā te whakamahi i ngā tikanga whakauru i runga i te kaupapa o te optoelectronics me te microelectronics. Ko...Pānuihia atu -
Te mātāpono o te whakamatao taiaho me tōna tono ki ngā ngota matao
Te mātāpono o te whakamatao irahiko me tōna whakamahinga ki ngā ngota matao I roto i te ahupūngao ngota matao, he nui ngā mahi whakamātautau e hiahia ana ki te whakahaere i ngā matūriki (te pupuri i ngā ngota ioni, pērā i ngā karaka ngota), te whakaroa i a rātou, me te whakapai ake i te tika o te ine. I te whanaketanga o te hangarau irahiko, ka mahi te irahiko...Pānuihia atu -
He kupu whakataki ki ngā taputapu whakaahua
He taputapu te pūoko whakaahua e huri ana i ngā tohu mārama hei tohu hiko. I roto i te pūoko whakaahua haurua-haurua, ka uru te kaikawe whakaahua e whakaohokia ana e te photon taupatupatu ki te ara iahiko o waho i raro i te ngaohiko whakahāngai ka hangaia he iahiko whakaahua e taea te ine. Ahakoa i te urupare mōrahi...Pānuihia atu -
He aha te taiaho tino tere
A. Te ariā o ngā taiaho tere rawa Ko ngā taiaho tere rawa e pā ana ki ngā taiaho raka-aratau e whakamahia ana hei tuku i ngā pāoro poto rawa, hei tauira, ngā pāoro o te roanga femtosecond, picosecond rānei.
