Kaula kamaʻilio optical, resonator optical lahilahi loa
Hiki i nā resonators optical ke hoʻokaʻawale i nā nalu lōʻihi o nā nalu māmā ma kahi palena, a he mau noi koʻikoʻi i ka launa pū ʻana o ka māmā me nā mea.kamaʻilio ʻike maka, ʻike ʻike maka, a me ka hoʻohui ʻana o ka maka. ʻO ka nui o ka resonator e hilinaʻi nui ʻia i nā ʻano mea a me ka nalu hana, no ka laʻana, ʻo nā resonators silicon e hana ana ma ka band infrared kokoke e koi pinepine i nā ʻano optical o nā haneli nanometers a ʻoi aku. I nā makahiki i hala iho nei, ua huki nui nā resonators optical planar ultra-thin ma muli o kā lākou hiki ke hoʻohana ʻia i ke kala hoʻonohonoho, ke kiʻi holographic, ka hoʻoponopono ʻana i ke kahua māmā a me nā mea optoelectronic. ʻO ke ʻano o ka hōʻemi ʻana i ka mānoanoa o nā resonators planar kekahi o nā pilikia paʻakikī i kū i nā mea noiʻi.
ʻOkoʻa nā mea hoʻokaʻawale topological 3D (e like me bismuth telluride, antimony telluride, bismuth selenide, a pēlā aku) he mau mea ʻike hou me nā kūlana ʻili metala i pale ʻia e topologically a me nā kūlana insulator. Pale ʻia ke kūlana ʻili e ka symmetry o ka hoʻohuli manawa, a ʻaʻole i hoʻopuehu ʻia kāna mau electrons e nā haumia non-magnetic, nona nā manaʻolana noi koʻikoʻi i ka helu quantum mana haʻahaʻa a me nā mea spintronic. I ka manawa like, hōʻike pū nā mea hoʻokaʻawale topological i nā waiwai optical maikaʻi loa, e like me ke kuhikuhi refractive kiʻekiʻe, ka nonlinear nui.ʻike makacoefficient, ka laulā spectrum hana ākea, ka tunability, ka hoʻohui maʻalahi, a me nā mea ʻē aʻe, kahi e hāʻawi ai i kahi kahua hou no ka hoʻokō ʻana i ka hoʻoponopono māmā anā mea hana optoelectronic.
Ua hāpai kekahi hui noiʻi ma Kina i kahi ʻano hana no ka hana ʻana i nā resonators optical ultra-thin ma ka hoʻohana ʻana i nā nanofilms insulator topological bismuth telluride e ulu nui ana. Hōʻike ka lua optical i nā ʻano absorption resonance maopopo i loko o ka band infrared kokoke. Loaʻa iā Bismuth telluride kahi index refractive kiʻekiʻe loa ma mua o 6 i loko o ka band kamaʻilio optical (ʻoi aku ka kiʻekiʻe ma mua o ka index refractive o nā mea index refractive kiʻekiʻe kuʻuna e like me silicon a me germanium), i hiki ai i ka mānoanoa o ka lua optical ke hiki i ka iwakālua o ka nalu resonance. I ka manawa like, ua waiho ʻia ka resonator optical ma luna o kahi kristal photonic hoʻokahi-dimensional, a ua ʻike ʻia kahi hopena transparency electromagnetically i hoʻokomo ʻia i loko o ka band kamaʻilio optical, ma muli o ka hoʻopili ʻana o ka resonator me ka plasmon Tamm a me kāna hoʻopilikia luku. ʻO ka pane spectral o kēia hopena e pili ana i ka mānoanoa o ka resonator optical a he paʻa i ka loli o ka index refractive ambient. Wehe kēia hana i kahi ala hou no ka hoʻokō ʻana i ka lua optical ultrathin, ka hoʻoponopono spectrum material insulator topological a me nā mea optoelectronic.
E like me ka mea i hōʻike ʻia ma ke Kiʻi 1a a me 1b, ʻo ka resonator optical ka mea nui i haku ʻia me kahi insulator topological bismuth telluride a me nā nanofilms kālā. ʻO nā nanofilms bismuth telluride i hoʻomākaukau ʻia e ka magnetron sputtering he wahi nui a me ka pālahalaha maikaʻi. Ke 42 nm a me 30 nm ka mānoanoa o nā kiʻiʻoniʻoni bismuth telluride a me ke kālā, ʻo ia hoʻi, hōʻike ka lua optical i ka absorption resonance ikaika ma ke kāʻei o 1100 ~ 1800 nm (Kiʻi 1c). I ka wā i hoʻohui ai nā mea noiʻi i kēia lua optical ma luna o kahi kristal photonic i hana ʻia me nā puʻu ʻokoʻa o nā papa Ta2O5 (182 nm) a me SiO2 (260 nm) (Kiʻi 1e), ua ʻike ʻia kahi awāwa absorption ʻokoʻa (Kiʻi 1f) kokoke i ka piko absorption resonant mua (~ 1550 nm), kahi like me ka hopena transparency i hoʻoulu ʻia e ka electromagnetically i hana ʻia e nā ʻōnaehana atomic.

Ua hōʻike ʻia ka mea bismuth telluride e ka microscopy electron transmission a me ka ellipsometry. Hōʻike ʻo FIG. 2a-2c i nā micrographs electron transmission (nā kiʻi hoʻonā kiʻekiʻe) a me nā ʻano diffraction electron i koho ʻia o nā nanofilms bismuth telluride. Hiki ke ʻike ʻia mai ke kiʻi he mau mea polycrystalline nā nanofilms bismuth telluride i hoʻomākaukau ʻia, a ʻo ke kuhikuhi ulu nui ʻo ia ka mokulele kristal (015). Hōʻike ʻo Figure 2d-2f i ka helu kuhikuhi refractive paʻakikī o ka bismuth telluride i ana ʻia e ka ellipsometer a me ke kūlana ʻili i hoʻopili ʻia a me ka helu kuhikuhi refractive paʻakikī o ka mokuʻāina. Hōʻike nā hopena ua ʻoi aku ka nui o ke coefficient extinction o ke kūlana ʻili ma mua o ka helu kuhikuhi refractive ma ka pae o 230 ~ 1930 nm, e hōʻike ana i nā ʻano like metala. ʻOi aku ka helu kuhikuhi refractive o ke kino ma mua o 6 ke ʻoi aku ka lōʻihi o ka nalu ma mua o 1385 nm, ʻoi aku ka kiʻekiʻe ma mua o ka silicon, germanium a me nā mea kuʻuna kiʻekiʻe refractive index ʻē aʻe i loko o kēia hui, kahi e waiho ai i ke kumu no ka hoʻomākaukau ʻana o nā resonators optical ultra-thin. Kuhikuhi nā mea noiʻi ʻo kēia ka ʻike mua i hōʻike ʻia o kahi topological insulator planar optical cavity me ka mānoanoa o nā ʻumi nanometers wale nō i loko o ke hui kamaʻilio optical. Ma hope mai, ua ana ʻia ka spectrum absorption a me ka lōʻihi o ka nalu resonance o ka lua optical ultra-thin me ka mānoanoa o bismuth telluride. ʻO ka hope loa, ua noiʻi ʻia ka hopena o ka mānoanoa o ka ʻili kālā ma nā spectra transparency i hoʻokomo ʻia e ka electromagnetically i loko o nā ʻano nanocavity/photonic crystal bismuth telluride.

Ma ka hoʻomākaukau ʻana i nā ʻili lahilahi pālahalaha nui o nā mea hoʻokaʻawale topological bismuth telluride, a me ka hoʻohana ʻana i ka index refractive ultra-kiʻekiʻe o nā mea Bismuth telluride ma kahi kokoke i ka band infrared, loaʻa kahi lua optical planar me ka mānoanoa o nā ʻumi nanometers wale nō. Hiki i ka lua optical ultra-thin ke hoʻomaopopo i ka absorption kukui resonant maikaʻi i ka band infrared kokoke, a he waiwai nui ka hoʻohana ʻana i ka hoʻomohala ʻana i nā mea optoelectronic i loko o ka band kamaʻilio optical. ʻO ka mānoanoa o ka lua optical bismuth telluride he linear i ka wavelength resonant, a ʻoi aku ka liʻiliʻi ma mua o ka silicon like a me ka germanium optical cavity. I ka manawa like, ua hoʻohui ʻia ka lua optical bismuth telluride me ka kristal photonic e hoʻokō i ka hopena optical anomalous e like me ka transparency i hoʻokomo ʻia e ka electromagnetically o ka ʻōnaehana atomic, e hāʻawi ana i kahi ʻano hana hou no ka hoʻoponopono spectrum o ka microstructure. He kuleana koʻikoʻi kēia haʻawina i ka hoʻolaha ʻana i ka noiʻi ʻana i nā mea insulator topological i ka hoʻoponopono kukui a me nā mea hana optical.
