Photonics Technology Development kom nrawm rau Daim Ntawv Thov Ntawm Pob Zeb Diamond

Kev nce qib hauv kev tsim cov pob zeb hluavtaws tau ua cov thev naus laus zis tshiab tau ua tau, tab sis ntau qhov kev sib tw tseem nyob rau cov thev naus laus zis tshiab no hauv kev pabcuam quantum daim ntawv thov.
Ntau xyoo dhau los los yog li ntawd, tau tsav los ntawm ntau qhov kev siv thev naus laus zis tseem ceeb thiab kev xav tau ntawm kev lag luam, ntau yam kev lag luam, cov thev naus laus zis photonics uas tau txais txiaj ntsig zoo ntawm lub cev tshwj xeeb ntawm pob zeb diamond tau pom kev nce qib tseem ceeb. Innovations nyob rau hauv lub synthesis ntawm optical zoo pob zeb diamond los ntawm tshuaj vapor deposition (CVD), pob zeb diamond xim chaw engineering, thiab technologies rau fabrication ntawm pob zeb diamond optical Cheebtsam thiab photonic lug tau ua rau cov kev nce qib no.
Photonics daim ntaub ntawv raws li pob zeb diamond zoo heev intrinsic zog
High purity diamond exhibits transparency in the frequency range from ultraviolet to terahertz and beyond. It has the highest room temperature thermal conductivity of any bulk material (>5 npaug ntawm tooj liab), thaum muaj qhov sib txawv ntawm cov thermo-optical coefficient. Cov khoom no ua rau pob zeb diamond optics zoo tagnrho rau kev siv hluav taws xob muaj zog laser, suav nrog kev siv tshuab, vuam thiab kev tsim khoom ntxiv, qhov twg nws muaj feem xyuam rau ntau qhov sib txawv ntawm electromagnetic spectrum.
Tsis tas li ntawd, pob zeb diamond yog qhov nyuaj tshaj plaws hauv ntiaj teb, thiab nws yog ib qho nyuaj heev thiab rugged, ua rau nws kuj zoo tagnrho rau kev tiv thaiv thiab kev ruaj ntseg daim ntaub ntawv uas yuav tsum tau rugged optical thiab infrared Cheebtsam thiab muaj peev xwm ua hauj lwm nyob rau hauv ib tug nyuaj heev puag ncig.
Optical zoo CVD pob zeb diamond muaj nyob rau hauv ib qho siv lead ua thiab polycrystalline cov ntaub ntawv. Qhov kom zoo dua ntawm pob zeb diamond polycrystalline yog tias nws tuaj yeem siv rau cov khoom siv loj loj hauv cheeb tsam txog li 135 hli. Piv txwv li, nws tuaj yeem siv los ua lub qhov rais rau lub zog siab 10.6 μm CO2 lasers rau huab ultraviolet (EUV) lithography tshuab rau cov khoom siv semiconductor tshaj plaws fabrication nodes.
Cov thev naus laus zis no, uas tau tsav los ntawm kev ua raws li Moore Txoj Cai, tso siab rau kev sib txuas thiab ua cov pob zeb diamond qhov rais kom nruj cov qauv kho qhov muag, vim tias tsis muaj lwm yam khoom siv kho qhov muag tuaj yeem ua haujlwm raws li qhov xav tau ntawm laser huab cua.
Scattering poob hauv polycrystalline CVD pob zeb diamond ntawm wavelengths luv dua li ntawm 1.5 μm txhais tau hais tias feem ntau cov ntawv thov nyob rau hauv qhov ntau yog hais txog siv ib lub pob zeb diamond. Vim muaj qhov txwv loj ntawm cov pob zeb diamond substrates tam sim no, ib lub pob zeb diamond ib leeg feem ntau nyob ib ncig ntawm 5-10 hli ntev, thiab txawm hais tias qee lub tuam txhab tab tom tsim cov pob zeb diamond loj loj ntawm cov pob zeb uas tsis yog pob zeb diamond substrates, cov khoom siv no tsis tuaj yeem. siv tau rau txhua daim ntawv thov kho qhov muag vim nws qhov kev sib zog siab sab hauv.
Txawm hais tias muaj kev txwv loj, qee cov txheej txheem ib leeg-crystal CVD pob zeb diamond photonics tau tsim, xws li pob zeb diamond Raman lasers raws li Element Six qhov tshwj xeeb qis-lub teeb-absorbing, low-birefringence crystals.
Cov nonlinear lasers siv qhov tshwm sim ntawm kev zoo siab Raman tawg los hloov lub twj tso kua mis mus rau Stokes-hloov tawm cov kab hluav taws xob, yog li nthuav dav ntau yam ntawm cov khoom siv laser rau cov ntawv thov tshiab npog UV rau IR, suav nrog: cov khoom siv vuam, 3D luam ntawv, qhia lub zog. , LIDAR, tej thaj chaw deb sensing, thiab laser coj hnub qub (LGS).
Pob zeb diamond muaj ib lub siab tshaj plaws Raman nce coefficients, uas, ua ke nrog nws zoo heev thermal conductivity, ua rau nws ib tug zoo tagnrho nce nruab nrab rau kev ua kom pom lub zog scaling thiab brightness li, nrog rau nyob rau hauv lub "tib neeg qhov muag nyab xeeb" spectral cheeb tsam ntawm 1.{{1} }.8m ib. Hauv qhov ntau, qhov kev xaiv ntawm cov khoom siv laser muaj yav dhau los tau txwv.
Nthuav Pob Zeb Diamond Daim Ntawv Thov los ntawm Xim Core Engineering
Thaum lub pob zeb diamond muaj cov txheej txheem zoo ntawm cov khoom siv kho qhov muag, nws kuj tseem muaj ntau pua qhov sib txawv ntawm qhov tsis xws luag (xim chaw). Qee qhov no yog qhov tseem ceeb rau cov kev siv uas siv lub quantum xeev ntawm lub teeb thiab cov khoom siv hluav taws xob ntawm cov chaw xim, suav nrog kev sib txuas lus quantum, quantum suav, thiab ntau yam kev siv sensing.
Ntawm qhov kev ceeb toom tshwj xeeb yog qhov chaw tsis muaj nitrogen (NV) xim chaw - lub teeb pom kev tsis zoo hauv pob zeb diamond uas tau ua raws li kev tshawb fawb hnyav vim muaj peev xwm los tswj nws lub xeev quantum yooj yim los ntawm kev siv lub teeb thiab RF teb ntawm chav tsev kub.
Nyob ntawm cov txheej txheem kev thov zaum kawg, ib tus tuaj yeem tsim NV xim chaw hauv ob txoj hauv kev. Ib qho yog los ntawm kev tswj cov doping ntawm nitrogen thaum lub sij hawm CVD txoj kev loj hlob kom cov nitrogen atoms faib thoob plaws hauv cov khoom ntawm qhov xav tau concentration. Ntawm qhov tod tes, kev tswj xyuas qhov tseeb ntawm tus kheej cov chaw xim yog xav tau, siv nitrogen txhaj. Lub lattice vacancy yog tom qab ntawd tsim los ntawm high-zog electron irradiation, thiab cov siv lead ua yog annealed nyob rau hauv siab kub los npaj cov chaw ua hauj lwm rau kev sib raug zoo nrog cov nitrogen atoms nyob rau hauv lub siv lead ua, ua rau NV xim chaw. Ib txoj hauv kev zoo sib xws tuaj yeem siv los tsim lwm qhov chaw xim xim xws li silicon vacancies (SiV) lossis germanium vacancies (GeV) chaw.
Rau kev ua cov ntaub ntawv quantum, arrays ntawm cov chaw xim yog xav tau - ob qho tib si los tswj lawv cov khoom quantum thiab kom ua tau zoo ob peb lub chaw ua ke los ntawm cov kab noj hniav photonic. Vim yog cov tshuaj inertness ntawm pob zeb diamond thiab tsis muaj kev lag luam thoob plaws, kev siv zog ntau thiab nyiaj txiag tseem xav tau los tsim cov txheej txheem nanofabrication uas xav tau rau cov qauv zoo li no; Txawm li cas los xij, nyob rau xyoo tas los no, cov kws tshawb fawb tau ua tiav zoo hauv cheeb tsam no, suav nrog kev tsim cov nanostructures nyuaj nyob rau hauv daim ntawv ntawm waveguides, kab, kab noj hniav, thiab disks, siv ntau hom kev yees duab photolithography, thiab siv plasma thiab reactive ion beams rau etching. .
Cov kev sib tw yav tom ntej rau kev ua tiav pob zeb diamond quantum photonics
Nyob rau hauv xyoo tas los no, cov kws tshawb fawb tau ua tiav cov txiaj ntsig tseem ceeb hauv kev tsim cov pob zeb diamond nrog cov khoom siv kho qhov muag zoo thiab cov chaw xim zoo nkauj, thiab tau ua kom muaj ntau yam tshiab thiab cov txheej txheem photonics uas twb muaj lawm.
Txawm li cas los xij, ntau qhov kev sib tw tseem nyob ua ntej cov ntawv thov pob zeb diamond hauv quantum photonics tuaj yeem ua tiav raws li cov chips scalable rau cov ntawv thov xws li kev ua cov ntaub ntawv quantum. Cov no muaj xws li: kev txhim kho cov xim-centered engineering thiab robustness ntawm quantum khoom; fabrication ntawm wafers; thiab hybrid kev koom ua ke nrog lwm cov ntaub ntawv photonic thiab cov khoom. Txawm hais tias muaj cov teeb meem no, kev tshawb fawb tam sim no qhia rau cov cheeb tsam no yog qhov muaj zog heev thiab yuav tsum muaj kev vam meej ntau hauv xyoo tom ntej.
