Ko te heru auau whatu he whānuitanga i titoa mai i tētahi raupapa o ngā wāhanga auau ōrite te mokowā i runga i te whānuitanga, ka taea te whakaputa mā ngā taiaho aratau-raka, ngā resonator, ngāngā whakarerekētanga hiko-whatuNgā heru auau whatu i hangaia engā kaiwhakatikatika hiko-whatuhe āhuatanga o te auau auau teitei, te whakamaroke ā-roto me te mana teitei, me ētahi atu, e whakamahia whānuitia ana i roto i te whakatikatika taputapu, te tirotiro ira, te ahupūngao taketake rānei, ā, kua nui haere te aro o ngā kairangahau i ngā tau tata nei.
Nō nā tata nei, i whakaputa a Alexandre Parriaux me ētahi atu o Te Whare Wānanga o Burgendi i Parani i tētahi pepa arotake i roto i te puka Advances in Optics and Photonics, e whakaatu ana i ngā ahunga whakamua rangahau hou me te tono o ngā heru auau whatu i hangaia ewhakarerekētanga hiko-whatuKei roto ko te whakaurunga o te heru auau whatu, te tikanga me ngā āhuatanga o te heru auau whatu i hangaia ekaiwhakarerekē hiko-whatu, ā, hei whakamutunga, ka whakarārangihia ngā horopaki tono okaiwhakarerekē hiko-whatuKa whakamāramahia te taipitopito o te heru auau whatu, tae atu ki te whakamahinga o te whānuitanga tika, te pokanoa o te heru whatu takirua, te whakatikatika taputapu me te whakaputa ngaru ā-wātea, ā, ka matapakihia hoki te mātāpono kei muri i ngā whakamahinga rerekē. Hei whakamutunga, ka hoatu e te kaituhi te tirohanga ki te hangarau heru auau whatu whakarerekētanga hiko-whatu.

E 60 tau ki muri i tēnei marama i hangaia ai e Tākuta Maiman te rēseri rupi tuatahi. E whā tau i muri mai, ko Hargrove, ko Fock me Pollack o Bell Laboratories i te Hononga o Amerika ngā tuatahi ki te pūrongo i te raka aratau hohe i tutuki i roto i ngā rēseri helium-neon, ko te whānuitanga rēseri raka aratau i roto i te rohe wā e tohuhia ana hei tukunga pātere, i roto i te rohe auau he raupapa o ngā rārangi poto motuhake me te tawhiti rite, he tino rite ki tā tātou whakamahinga o ia rā o ngā heru, nō reira ka kiia e mātou tēnei whānuitanga ko te "heru auau whatu". E kiia ana ko te "heru auau whatu".
Nā te pai o te whakamahinga o te heru whatu, i whakawhiwhia te Tohu Nobel mō te Ahupūngao i te tau 2005 ki a Hansch rāua ko Hall, nā rāua i mahi tuatahi ki te hangarau heru whatu, mai i taua wā, kua eke te whanaketanga o te heru whatu ki tētahi taumata hou. Nā te mea he rerekē ngā whakaritenga mō ngā heru whatu i ngā whakamahinga rerekē, pērā i te mana, te mokowā rārangi me te roangaru pokapū, kua arahina tēnei ki te hiahia ki te whakamahi i ngā tikanga whakamātautau rerekē hei whakaputa i ngā heru whatu, pērā i ngā taiaho aratau-raka, ngā moroiti-whakaoho me te whakarerekētanga hiko-whatu.

Pūtake ahua: Ngā heru auau hiko-whatu
Mai i te kitenga o ngā heru auau whatu, ko te nuinga o ngā heru auau whatu kua hangaia mā te whakamahi i ngā taiaho raka-aratau. I roto i ngā taiaho raka-aratau, ka whakamahia he kōhao me te wā haerenga-hoki o τ hei whakatika i te whanaungatanga ā-wāhanga i waenga i ngā aratau roa, kia taea ai te whakatau i te tere tukurua o te taiaho, e taea ana te noho mai i te megahertz (MHz) ki te gigahertz (GHz).
Ko te heru auau whatu i hangaia e te micro-resonator e ahu mai ana i ngā pānga kore-raina, ā, ko te wā haere-hoki ka whakatauhia e te roa o te moko-iti, nā te mea he iti iho i te 1mm te roa o te moko-iti, ko te heru auau whatu i hangaia e te moko-iti he 10 gigahertz ki te 1 terahertz. E toru ngā momo moko-iti e kitea whānuitia ana, arā, ko ngā microtubules, ko ngā microspheres me ngā microrings. Mā te whakamahi i ngā pānga kore-raina i roto i ngā muka whatu, pērā i te marara Brillouin, te whakaranu ngaru-whā rānei, me ngā moko-iti, ka taea te whakaputa i ngā heru auau whatu i roto i te whānuitanga tekau nanometer. Hei tāpiri, ka taea hoki te whakaputa i ngā heru auau whatu mā te whakamahi i ētahi modulators acousto-whatu.
