Ka pololei o ka mīkini ʻāpana
Pono nā kānana Q-Kiʻekiʻe i ka pololei kiʻekiʻe loa i ka mīkini ʻāpana. ʻOiai nā ʻokoʻa liʻiliʻi i ka nui, ke ʻano, a i ʻole ke kūlana hiki ke hoʻopilikia nui i ka hana o ke kānana a me ka Q-factor. No ka laʻana, i nā kānana lua, ʻo nā ana a me ka ʻili o ka lua e hoʻopilikia pololei i ka Q-factor. No ka hoʻokō ʻana i kahi Q-factor kiʻekiʻe, pono e mīkini ʻia nā ʻāpana me ka pololei kiʻekiʻe, e koi pinepine ana i nā ʻenehana hana holomua e like me ka mīkini CNC pololei a i ʻole ka ʻoki laser. Hoʻohana ʻia nā ʻenehana hana additive e like me ka hoʻoheheʻe laser koho e hoʻomaikaʻi i ka pololei o nā ʻāpana a me ka hana hou ʻana.

Koho Mea a me ka Mana Kūlana
He mea koʻikoʻi ke koho ʻana i nā mea no nā kānana Q-kiʻekiʻe. Pono nā mea me ka pohō haʻahaʻa a me ke kūpaʻa kiʻekiʻe e hōʻemi i ka pohō ikehu a hōʻoia i ka hana paʻa. ʻO nā mea maʻamau e komo pū me nā metala maʻemaʻe kiʻekiʻe (e laʻa, keleawe, alumini) a me nā dielectrics pohō haʻahaʻa (e laʻa, nā keramika alumina). Eia naʻe, he pipiʻi pinepine kēia mau mea a he paʻakikī ke hana. Eia kekahi, pono ka kaohi maikaʻi koʻikoʻi i ka wā o ke koho ʻana a me ka hana ʻana i nā mea e hōʻoia i ke kūlike o nā waiwai mea. ʻO nā mea haumia a i ʻole nā ​​​​hemahema i loko o nā mea hiki ke alakaʻi i ka pohō ikehu a me ka hoʻemi ʻana i ka Q-factor.

ʻAhahui a me ka Hoʻonohonoho Pololei
ʻO ke kaʻina hana hōʻuluʻulu nonā kānana Q-kiʻekiʻepono e pololei loa. Pono e hoʻonoho pololei ʻia nā ʻāpana a hoʻākoakoa ʻia e pale aku i ka hewa a i ʻole nā ​​hakahaka, kahi e hiki ai ke hoʻohaʻahaʻa i ka hana o ke kānana. No nā kānana Q kiʻekiʻe hiki ke hoʻololi ʻia, ʻo ka hoʻohui ʻana o nā ʻano hana hoʻonohonoho me ka lua kānana e hōʻike ana i nā pilikia hou aʻe. No ka laʻana, i nā kānana resonator dielectric me nā ʻano hana hoʻonohonoho MEMS, ʻoi aku ka liʻiliʻi o ka nui o nā actuators MEMS ma mua o ka resonator. Inā hana ʻokoʻa ʻia ka resonator a me nā actuators MEMS, lilo ke kaʻina hana hōʻuluʻulu i mea paʻakikī a pipiʻi hoʻi, a hiki i nā hewa liʻiliʻi ke hoʻopilikia i ka hana hoʻonohonoho o ke kānana.

Ka hoʻokō ʻana i ka Bandwidth Mau a me ka Tunability
He mea paʻakikī ka hoʻolālā ʻana i kahi kānana hiki ke hoʻololi ʻia me ka bandwidth mau. No ka mālama ʻana i ka bandwidth mau i ka wā e hoʻonohonoho ana, pono e loli pololei ka Qe i hoʻouka ʻia ma waho me ke alapine waena, ʻoiai ʻo nā hui inter-resonator e loli like me ke alapine waena. ʻO ka hapa nui o nā kānana hiki ke hoʻololi ʻia i hōʻike ʻia ma ka palapala e hōʻike ana i ka hoʻohaʻahaʻa ʻana o ka hana a me nā ʻano bandwidth. Hoʻohana ʻia nā ʻano hana e like me nā hui uila a me nā magnetic i kaulike ʻia e hoʻolālā i nā kānana hiki ke hoʻololi ʻia me ka bandwidth mau, akā paʻakikī mau ka hoʻokō ʻana i kēia ma ka hana. No ka laʻana, ua hōʻike ʻia kahi kānana lua ʻano pālua TE113 hiki ke hoʻololi ʻia e hoʻokō i kahi Q-factor kiʻekiʻe o 3000 ma luna o kona laulā hoʻonohonoho, akā ua hiki nō kona ʻano bandwidth i ± 3.1% i loko o kahi laulā hoʻonohonoho liʻiliʻi.

Nā hemahema hana a me ka hana nui
ʻO nā hemahema hana e like me ke ʻano, ka nui, a me nā ʻokoʻa kūlana hiki ke hoʻolauna i ka momentum hou i ke ʻano, e alakaʻi ana i ka hoʻopili ʻana o ke ʻano ma nā wahi like ʻole ma ka k-space a me ka hoʻokumu ʻana o nā kahawai radiative keu, a laila e hōʻemi ana i ka Q-factor. No nā mea hana nanophotonic free-space, ʻo ka wahi hana nui a me nā kahawai pohō hou aʻe e pili ana me nā nanostructure arrays e paʻakikī ai ka hoʻokō ʻana i nā Q-factors kiʻekiʻe. ʻOiai ua hōʻike nā hoʻokō hoʻokolohua i nā Q-factors e like me 10⁹ i nā microresonators ma ka chip, ʻo ka hana nui ʻana o nā kānana Q-kiʻekiʻe he mea pipiʻi pinepine a hoʻopau manawa. Hoʻohana ʻia nā ʻano hana e like me ka grayscale photolithography e hana i nā wafer-scale filter arrays, akā ʻo ka hoʻokō ʻana i nā Q-factors kiʻekiʻe i ka hana nui ʻana he mea paʻakikī mau ia.

Ka Palena Ma waena o ka Hana a me ke Kumukūʻai
ʻO ka maʻamau, koi nā kānana High-Q i nā hoʻolālā paʻakikī a me nā kaʻina hana hana kiʻekiʻe e hoʻokō ai i ka hana kiʻekiʻe, kahi e hoʻonui nui ai i nā kumukūʻai hana. I nā noi hana, aia kahi pono e kaulike i ka hana a me ke kumukūʻai. No ka laʻana, ʻae ka ʻenehana micromachining silicon i ka hana ʻana o ka batch haʻahaʻa o nā resonators tunable a me nā kānana ma nā alapine haʻahaʻa. Eia nō naʻe, ʻaʻole i ʻimi ʻia ka hoʻokō ʻana i nā Q-factors kiʻekiʻe i nā alapine kiʻekiʻe. ʻO ka hoʻohui ʻana i ka ʻenehana hoʻonohonoho silicon RF MEMS me nā ʻano hana hoʻoheheʻe injection kūpono e hāʻawi i kahi hopena kūpono no ka hana ʻana i nā kānana kiʻekiʻe-Q me ke kumu kūʻai haʻahaʻa me ka mālama ʻana i ka hana kiʻekiʻe.
