Ngā tono hou mōHiko-Whiti kaiwhakarerekētanga wāhanga
Kaiwhakarerekē LiNbO3He mea nui te whakarerekētanga ā-wāhanga e taea ai te whakahaere i te huringa ā-wāhanga o te ngaru mārama, ā, he mahi matua tāna i roto i te whakawhitiwhiti kōrero whatu me te rongonga o ēnei rā. Nō nā tata nei, kua puta he momo hou okaiwhakarerekētanga wāhangakua kukume i te aro o ngā kairangahau me ngā kaihangarau, e mahi ana i ngā roangaru e toru o te 780nm, 850nm me te 1064nm, me ngā whānuitanga whakarerekētanga tae atu ki te 300MHz, 10GHz, 20GHz me te 40GHz.
Ko te āhuatanga tino nui o tēnei pūwhakarerekētanga ā-wāhanga ko te whānui o te whānuitanga o te whakarerekētanga me te iti o te ngaronga whakaurunga. Ko te ngaronga whakaurunga e pā ana ki te hekenga o te kaha, te pūngao rānei o te tohu whatu i muri i te haere i roto i te pūwhakarerekētanga. He tino iti te ngaronga whakaurunga o tēnei pūwhakarerekētanga ā-wāhanga, e whakarite ana i te pono o te tohu, kia taea ai e te tohu te pupuri i te kaha teitei i muri i te whakarerekētanga.
Hei tāpiritanga, ko te āhuatanga o te pūwhakarerekētanga ā-wāhanga ko te ngaohiko haurua-ngaru iti. Ko te ngaohiko haurua-ngaru te ngaohiko e hiahiatia ana kia whakamahia ki te pūwhakarerekētanga hei whakarerekē i te ā-wāhanga o te mārama mā te 180 nekehanga. Ko te tikanga o te ngaohiko haurua-ngaru iti he ngaohiko iti noa iho e hiahiatia ana hei whakatutuki i te huringa nui o te ā-wāhanga whatu, e tino whakaiti ana i te whakapaunga pūngao o te taputapu.
Mō ngā mara tono, ka taea te whakamahi whānui i tēnei pūwhakatikatika ā-wāhanga hou i roto i te pūoko muka whatu, te whakawhitiwhiti muka whatu, te whakaroa ā-wāhanga (kaitahuri), me te whakawhitiwhiti irahiko. I roto i te pūoko muka whatu, ka taea e te pūwhakatikatika ā-wāhanga te whakapai ake i te aro me te taumira o te pūoko. I roto i te whakawhitiwhiti muka whatu, ka taea e ia te whakapai ake i te tere whakawhitiwhiti me te pai o te tuku raraunga. I roto i te whakaroa ā-wāhanga (kaitahuri), ka taea e ia te whakahaere tika i te ahunga o te horapa o te mārama; I roto i te whakawhitiwhiti irahiko, ka taea te whakamahi hei whakahaere me te whakahaere i ngā āhua irahiko.
I te nuinga o te wā, ka whakaratohia mai e te pūwhakarerekētanga ā-wāhanga hou he tikanga whakahaere whatu pai ake, tika ake hoki, ka kawea mai ai ngā huringa hou ki ngā mara maha. E tumanako ana mātou ka whanakehia ake, ka tino pai ake hoki tēnei hangarau ā muri ake nei, ka hurahia mai ai ētahi atu mea ngaro whatu mā mātou.
