Lub tswv yim ntawm kev sib xyaw ua ke optics tau muab tso rau pem hauv ntej los ntawm Dr. Miller ntawm Bell Laboratories hauv xyoo 1969. Kev sib xyaw ua ke optics yog ib qho kev kawm tshiab uas kawm thiab tsim cov khoom siv kho qhov muag thiab cov khoom siv hluav taws xob sib xyaw ua ke siv cov txheej txheem sib xyaw ua ke ntawm optoelectronics thiab microelectronics. Lub hauv paus theoretical ntawm kev sib xyaw ua ke optics yog optics thiab optoelectronics, uas muaj cov wave optics thiab cov ntaub ntawv optics, nonlinear optics, semiconductor optoelectronics, crystal optics, thin film optics, guided wave optics, coupled mode thiab parametric interaction theory, thin film optical waveguide devices thiab systems. Lub hauv paus thev naus laus zis yog feem ntau yog thin film technology thiab microelectronics technology. Daim teb thov ntawm kev sib xyaw ua ke optics yog dav heev, ntxiv rau kev sib txuas lus fiber ntau optical, optical fiber sensing technology, optical information processing, optical computer thiab optical storage, muaj lwm yam teb, xws li kev tshawb fawb txog cov ntaub ntawv, cov cuab yeej optical, kev tshawb fawb spectral.
Ua ntej, kev sib xyaw ua ke ntawm qhov zoo ntawm qhov muag
1. Kev sib piv nrog cov kab ke kho qhov muag sib cais
Cov khoom siv kho qhov muag sib cais yog ib hom khoom siv kho qhov muag uas tau teeb tsa rau ntawm lub platform loj lossis lub hauv paus kho qhov muag los tsim ib lub tshuab kho qhov muag. Qhov loj ntawm lub tshuab yog li ntawm 1m2, thiab qhov tuab ntawm lub teeb yog li 1cm. Ntxiv rau nws qhov loj me, kev sib dhos thiab kev kho kuj nyuaj dua. Lub tshuab kho qhov muag sib xyaw ua ke muaj cov txiaj ntsig hauv qab no:
1. Cov nthwv dej teeb pom kev zoo kis mus rau hauv cov nthwv dej pom kev, thiab cov nthwv dej teeb pom kev yooj yim los tswj thiab tswj lawv lub zog.
2. Kev sib koom ua ke coj qhov chaw ruaj khov. Raws li tau hais los saum toj no, cov khoom siv sib xyaw ua ke xav kom ua ntau yam khoom siv ntawm tib lub substrate, yog li tsis muaj teeb meem sib dhos zoo li cov khoom siv sib cais muaj, yog li kev sib xyaw ua ke tuaj yeem ruaj khov, yog li nws kuj tseem hloov kho tau zoo dua rau cov yam ntxwv ib puag ncig xws li kev co thiab kub.
(3) Qhov loj ntawm lub cuab yeej thiab qhov ntev ntawm kev sib cuam tshuam raug luv dua; Cov khoom siv hluav taws xob cuam tshuam kuj ua haujlwm ntawm qhov hluav taws xob qis dua.
4. Lub zog ceev ceev. Lub teeb xa mus rau ntawm lub waveguide tsuas yog nyob rau hauv ib qho chaw me me hauv zos, ua rau muaj lub zog ceev ceev optical siab, uas yooj yim mus txog qhov tsim nyog ntawm cov cuab yeej ua haujlwm thiab ua haujlwm nrog cov teebmeem optical nonlinear.
5. cov khoom siv sib xyaw ua ke feem ntau yog sib xyaw ua ke ntawm cov khoom siv centimeter-scale, uas yog me me thiab lub teeb hauv qhov hnyav.
2. Kev sib piv nrog cov circuits sib xyaw ua ke
Qhov zoo ntawm kev sib koom ua ke ntawm optical muaj peev xwm muab faib ua ob yam, ib qho yog hloov lub tshuab hluav taws xob sib xyaw ua ke (integrated circuit) nrog lub tshuab kho qhov muag sib xyaw ua ke (integrated optical circuit); Qhov thib ob yog hais txog cov fiber ntau optical thiab dielectric plane optical waveguide uas coj cov nthwv dej teeb es tsis txhob siv hlau lossis coaxial cable los xa cov teeb liab.
Hauv txoj kev sib xyaw ua ke ntawm lub teeb pom kev zoo, cov khoom siv teeb pom kev zoo tau tsim rau ntawm lub wafer substrate thiab txuas nrog los ntawm cov waveguides teeb pom kev zoo uas tsim sab hauv lossis ntawm qhov chaw ntawm lub substrate. Txoj kev sib xyaw ua ke ntawm lub teeb pom kev zoo, uas sib xyaw ua ke cov khoom siv teeb pom kev zoo ntawm tib lub substrate hauv daim ntawv ntawm zaj duab xis nyias, yog ib txoj hauv kev tseem ceeb los daws qhov miniaturization ntawm lub kaw lus teeb pom kev zoo qub thiab txhim kho kev ua tau zoo tag nrho. Lub cuab yeej sib xyaw ua ke muaj qhov zoo ntawm qhov me me, kev ua haujlwm ruaj khov thiab txhim khu kev qha, kev ua haujlwm siab, kev siv hluav taws xob tsawg thiab kev siv yooj yim.
Feem ntau, qhov zoo ntawm kev hloov cov integrated circuits nrog cov integrated optical circuits suav nrog kev nce bandwidth, wavelength division multiplexing, multiplex switching, me me coupling poob, me me, lub teeb yuag, tsawg zog siv, zoo batch preparation economy, thiab kev ntseeg siab siab. Vim muaj ntau yam kev sib cuam tshuam ntawm lub teeb thiab khoom, cov haujlwm tshiab ntawm cov khoom siv kuj tuaj yeem ua tiav los ntawm kev siv ntau yam teebmeem lub cev xws li photoelectric effect, electro-optical effect, acousto-optical effect, magneto-optical effect, thermo-optical effect thiab lwm yam hauv cov khoom sib xyaw ntawm txoj kev optical integrated.
2. Kev tshawb fawb thiab kev siv cov optics sib xyaw ua ke
Kev sib xyaw ua ke optics yog siv dav hauv ntau qhov chaw xws li kev lag luam, tub rog thiab kev lag luam, tab sis nws feem ntau yog siv rau hauv cov hauv qab no:
1. Kev sib txuas lus thiab kev sib txuas lus kho qhov muag
Cov khoom siv sib xyaw ua ke ntawm cov kho vajtse yog cov khoom siv tseem ceeb los ua kom muaj kev sib txuas lus ceev ceev thiab muaj peev xwm loj, suav nrog cov laser source teb ceev ceev, waveguide grating array dense wavelength division multiplexer, narrowband teb integrated photodetector, routing wavelength converter, fast response optical switching matrix, low loss multiple access waveguide beam splitter thiab lwm yam.
2. Lub khoos phis tawj photonic
Lub khoos phis tawj hu ua photon yog lub khoos phis tawj uas siv lub teeb ua lub hauv paus xa cov ntaub ntawv. Photons yog bosons, uas tsis muaj hluav taws xob, thiab lub teeb ci tuaj yeem hla mus rau hauv ib qho sib luag lossis hla yam tsis cuam tshuam rau ib leeg, uas muaj peev xwm ua tiav cov txheej txheem sib luag zoo. Lub khoos phis tawj photonic kuj muaj qhov zoo ntawm kev khaws cov ntaub ntawv loj, muaj peev xwm tiv thaiv kev cuam tshuam zoo, tsis tas yuav tsum tau ua raws li qhov xwm txheej ib puag ncig, thiab muaj zog ua kom tsis txhob ua yuam kev. Cov khoom siv ua haujlwm yooj yim tshaj plaws ntawm cov khoos phis tawj photonic yog cov khoom siv hloov kho qhov muag thiab cov khoom siv kho qhov muag sib xyaw.
3. Lwm yam kev siv, xws li cov khoom siv kho qhov muag, lub sensor fiber optic, lub sensor fiber grating, lub gyroscope fiber optic, thiab lwm yam.
