I-Optical Confication Band, umgcini we-Ultra-Fightical Resonator
Ama-sponatoron abonakalayo angeza ezami amagagasi athile amagagasi akhanyayo endaweni elinganiselwe, futhi abe nezicelo ezibalulekile ekuxhumaneni okungumbala,Ukuxhumana kwe-Optical, Ukuzwa okubonakalayo, nokuhlanganiswa kokubona. Ubungako bomthengisi ikakhulukazi buya ngezimpawu ezibonakalayo kanye ne-waveleng esebenzayo, isibonelo, ama-silicon abadlali abasebenza eqenjini eliseduze le-infrared adinga ukwakheka kwamakhulu ama-nanometers nangaphezulu. Eminyakeni yamuva nje, ama-plan-ama-ultra-mncane planethi aphostoli adonsela ukunakwa okukhulu ngenxa yezinhlelo zawo ezingaba khona ngombala wesakhiwo, ukucabanga kwe-holographic, ukulawulwa kwensimu ekhanyayo kanye namadivayisi we-optoelectronic kanye namadivayisi we-optoelectronic kanye namadivayisi we-optoelectronic kanye namadivayisi we-optoelectronic kanye namadivayisi we-optoelectronic. Unganciphisa kanjani ubukhulu bePlanethi Resonators kungenye yezinkinga ezinzima ababhekene nazo abacwaningi.
Okuhlukile kwezinto zokwenziwa ze-semiconductor, ama-insurators we-3D we-toplical arluride, i-antimony telteride, i-belenide ye-bismuth, njll.) Izinsiza zolwazi ezivikelekile zensimbi ezivikelwe nge-insulator. Isimo esingaphezulu komhlaba sivikelwe ukuvumelanisa isikhathi sokungenisa isikhathi, futhi ama-elektroni awo awahlakazekile ngokungcola okungewona uMagnetic, onamathemba okusebenza abalulekile e-computer ephansi yamandla nama-spiptronic. Ngasikhathi sinye, izinto zokwenziwa ze-insulator ze-topological nazo zibonisa izakhiwo ezinhle kakhulu ze-Optical, njengezinkomba eziphezulu eziphezulu, okungezona ezingekho emthethweni-phathelene nokubonaI-coefficient, ububanzi be-spectrum uhla, ukuguquguquka, ukuhlanganiswa okulula, njll.Amadivayisi we-Optoelectronic.
Iqembu labacwaningi eChina lihlongoze indlela yokwakhiwa kwama-promonars a-Ultra-mncane ngokusebenzisa indawo enkulu ekhulisa i-bismuth arluride toologilongo ye-nanofilms. I-optical cavity ikhombisa izici ezisobala zokufakwa kokutholwa kwebhendi eseduze ye-infrared. I-Bismuth Orluride inenkomba ephakeme kakhulu yokuphinda i-6 ebhendini yokuxhumana ye-Optical Ngasikhathi sinye, i-optical resonator ifakwa kwi-crystal eyodwa enezici-hlobo, bese kuthi inoveli yokufakelwa kwe-trapparnnestication Effect ibonwa ebhendi lokuxhumana le-Optical Ukuphendula okubonakalayo kwalomphumela kuncike ekubumbeni komthengisi we-optical Lo msebenzi uvula indlela entsha yokugcwaliseka kwe-Ultrathin Optical Cavity, umthetho we-insulator we-insulator wezinto ezibonakalayo zokulawulwa kokulawulwa kwamadivayisi kanye namadivayisi we-optoelectronic.
Njengoba kukhonjisiwe ku-Fig. I-1A ne-1b, umgcini we-optical lononator wakhiwa ikakhulukazi i-bismuth arluride insulide yezenkolo ne-nanofilms yesiliva. Ama-bismuth arluride nanofilms alungiselelwe yi-magnetron sputtering anendawo enkulu kanye nefulethi elihle. Lapho ubukhulu be-bismuth merluride kanye namafilimu esiliva kungu-42 nm no-30 nm, ngokulandelana, i-cavity ye-optical ekhombisa ukumunca amandla okubukisa ngokuqinile ebhendi ka-1100 ~ 1800 nm (isithombe 1c). Lapho abaphenyi behlanganisa le ndawo ebonakalayo ekwi-crystal ye-Photonic eyenziwe ngezitaki ze-TA2O5 (182 NM) kanye ne-SAME2 (1550 NM), okufana nethonya lokufakelwa ngokusobala elikhiqizwa yi-atomic.

Izinto ze-bismuth merturide zazibonakala ngokudlulisela i-lelliescopy microscopy kanye ne-ellipsometry. Fig. I-2A-2c ikhombisa ukuhambisa ama-elektroni ama-micronch (izithombe ezinesinqumo esiphakeme) kanye namaphethini wokuphazamiseka we-elektroni akhethiwe we-bismuth arluride nanofilms. Kungabonakala esifanekisweni ukuthi ama-bismuth arluride alungiselelwe ama-nanofilms ayizinto ze-polycrystalline, kanye nokukhula okuphambili kokukhula (015) indiza ye-crystal. Umdwebo we-2D-2F ukhombisa inkomba eyinkimbinkimbi ye-bismuth merteride ekalwa yi-ellipsometer kanye nesimo esilinganiselwe sobuso kanye ne-State eyinkimbinkimbi yenkomba ye-standard eyinkimbinkimbi. Imiphumela ikhombisa ukuthi i-coeffiction ekhokhelwayo yezwe elingaphezulu komhlaba inkulu kune-Index Resuaction ebangeni lama-230 ~ 1930 nm, ekhombisa izici zensimbi. Inkomba evulekayo yomzimba ingaphezu kuka-6 lapho i-wavelength inkulu kune-1385 nm, ephakeme kakhulu kunaleso se-silico, i-germanium nezinye izinto zenkomba eziphakeme zenkomba eziphakeme kuleli bhendi, ebeka isisekelo sokulungiselela ama-ultra-mncane ama-resonators. Abaphenyi bakhomba ukuthi lokhu kungukuqala kokuqashelwa kwe-insulator planethi ye-insulator ye-insular enobukhulu bamashumi ama-nanometers ebhendi lokuxhumana. Kamuva, i-spectrum yokumunca kanye nokubuyiselwa kwe-waven-mncane ye-ultra-mncane yalinganiswa ngobukhulu be-bismuth allteride. Ekugcineni, umphumela wokugqitshwa kwefilimu kwesiliva ku-Electromagnetical Onderchetic Spectra Spectra ku-Bismuth Ourluride Nanocavity / Izakhiwo ze-Photonic Crystal ziyaphenywa

Ngokulungiselela indawo enkulu yamafilimu amancane amancane we-bismuth arluride opoturango, futhi asebenzise insizakalo ye-ultra-high resurive yezinto zokwakha ama-bismuth e-brismuth active worles ebhendini eliseduze ye-infrared, i-planar aptical enobukhulu bamashumi ama-nanometer atholakala. I-Ultra-Fight Optical Cavity ingabona ukumuncwa kokukhanya okusebenzayo kubhendi eduzane ne-infrared band, futhi inenani lesicelo elibalulekile ekuthuthukisweni kwamadivayisi we-optoelectronic ebhendi ye-optoelectonic. Ubukhulu be-bismuth arluride apticial cavity ilandelana liqonde ku-wavelength resonant, futhi lincane kunalolo lwe-silicon ne-germanium aptical cavity. Ngasikhathi sinye, i-bismuth arluride aptical cavity ihlanganiswe ne-Photonic Crystal ukufeza umphumela wokukhanya okungathandeki okufana nokusobala okubangelwa yi-athomu kwe-athomu, okunikezela indlela entsha yokulawulwa kokubumba kwe-miscrumple. Lolu cwaningo lubamba iqhaza elithile ekuthuthukiseni ucwaningo lwezinto zokwenziwa ze-insulator ze-topological ekusebenzeni okukhanyayo kanye namadivayisi asebenza ngokukhanya.
