Lub tswv yim ntawm kev sib koom ua ke optics tau muab tso rau los ntawm Dr. Miller ntawm Bell Laboratories hauv xyoo 1969. Integrated optics yog ib qho kev kawm tshiab uas kawm thiab tsim kho cov khoom siv kho qhov muag thiab hybrid optical electronic device systems siv cov kev sib xyaw ua ke raws li optoelectronics thiab microelectronics. Lub hauv paus theoretical ntawm kev sib xyaw optics yog optics thiab optoelectronics, suav nrog yoj optics thiab cov ntaub ntawv optics, nonlinear optics, semiconductor optoelectronics, siv lead ua optics, nyias zaj duab xis optics, coj yoj optics, ua ke hom thiab parametric kev sib cuam tshuam txoj kev xav, nyias zaj duab xis optical waveguide cov cuab yeej thiab tshuab. Lub hauv paus thev naus laus zis feem ntau yog nyias zaj duab xis thev naus laus zis thiab microelectronics thev naus laus zis. Daim ntawv thov teb ntawm kev sib xyaw optics yog dav heev, ntxiv rau kev sib txuas lus fiber ntau, kho qhov muag fiber ntau siv tshuab, kho cov ntaub ntawv kho qhov muag, kho qhov muag khoos phis tawj thiab kho qhov muag, muaj lwm yam kev tshawb fawb, xws li kev tshawb fawb txog cov khoom siv kho qhov muag, cov cuab yeej kho qhov muag, kev tshawb fawb spectral.
Ua ntej, integrated optical zoo
1. Sib piv nrog discrete optical device systems
Discrete optical device yog ib hom kev kho qhov muag kho qhov muag ntawm lub platform loj lossis kho qhov muag los tsim ib qho kev kho qhov muag. Qhov loj ntawm lub kaw lus yog nyob ntawm qhov kev txiav txim ntawm 1m2, thiab lub thickness ntawm lub nqaj yog hais txog 1cm. Ntxiv rau nws qhov loj me, kev sib dhos thiab kev hloov kho kuj nyuaj dua. Lub integrated optical system muaj qhov zoo hauv qab no:
1. Lub teeb nthwv dej nthuav dav hauv cov kab hluav taws xob kho qhov muag, thiab lub teeb nthwv dej yog qhov 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 no, kev sib koom ua ke optics xav kom ua ntau yam khoom siv ntawm tib lub substrate, yog li tsis muaj teeb meem sib dhos uas tsis sib xws ntawm optics muaj, yog li kev sib xyaw ua ke tuaj yeem ruaj khov, yog li nws kuj tseem hloov tau ntau dua rau ib puag ncig xws li kev co thiab kub. .
(3) Cov cuab yeej loj thiab kev sib cuam tshuam ntev yog luv; Cov khoom siv hluav taws xob cuam tshuam kuj tseem ua haujlwm ntawm cov hluav taws xob qis dua.
4. Muaj zog ceev ceev. Lub teeb kis tau los ntawm lub waveguide yog nyob rau hauv ib qho chaw me me hauv zos, uas ua rau lub zog kho qhov muag muaj zog, uas yooj yim mus txog qhov tsim nyog cov cuab yeej ua haujlwm pib thiab ua haujlwm nrog cov teebmeem uas tsis yog-linear optical.
5. Kev sib xyaw ua ke ntawm optics feem ntau yog sib xyaw ua ke ntawm ib lub centimeter-scale substrate, uas yog qhov me me thiab lub teeb hauv qhov hnyav.
2. Kev sib piv nrog kev sib xyaw ua ke
Qhov zoo ntawm kev sib koom ua ke kho qhov muag tuaj yeem muab faib ua ob yam, ib qho yog los hloov cov khoom siv hluav taws xob sib xyaw ua ke (kev sib koom ua ke) nrog kev sib xyaw ua ke ntawm optical system (integrated optical circuit); Lwm qhov yog cuam tshuam nrog cov fiber ntau optical thiab dielectric dav hlau optical waveguide uas coj lub teeb yoj es tsis txhob siv cov xaim lossis coaxial cable los xa cov teeb liab.
Nyob rau hauv ib txoj kev kho qhov muag, cov ntsiab lus kho qhov muag yog tsim los ntawm wafer substrate thiab txuas nrog optical waveguides tsim sab hauv lossis ntawm qhov chaw ntawm lub substrate. Txoj kev kho qhov muag sib xyaw ua ke, uas sib koom ua ke ntawm cov khoom siv kho qhov muag ntawm tib lub substrate hauv daim ntawv ntawm cov yeeb yaj kiab nyias, yog ib txoj hauv kev tseem ceeb los daws qhov miniaturization ntawm qhov qub optical system thiab txhim kho kev ua tau zoo tag nrho. Cov khoom sib xyaw ua ke muaj qhov zoo ntawm qhov me me, ruaj khov thiab txhim khu kev qha, kev ua haujlwm siab, kev siv hluav taws xob tsawg thiab siv tau yooj yim.
Feem ntau, qhov zoo ntawm kev hloov cov kev sib txuas sib txuas nrog kev sib xyaw ua ke ntawm cov khoom siv kho qhov muag suav nrog kev nce bandwidth, wavelength division multiplexing, multiplex switching, me coupling poob, me me, lub teeb yuag, tsis tshua muaj zog noj, zoo batch npaj kev lag luam, thiab kev ntseeg siab. Vim muaj ntau yam kev sib cuam tshuam ntawm lub teeb thiab teeb meem, cov cuab yeej tshiab tuaj yeem ua tiav los ntawm kev siv ntau yam teebmeem ntawm lub cev xws li photoelectric effect, electro-optical effect, acousto-optical effect, magneto-optical effect, thermo-optical effect thiab lwm yam. muaj pes tsawg leeg ntawm txoj kev kho qhov muag integrated.
2. Kev tshawb fawb thiab kev siv cov optics integrated
Integrated optics yog dav siv nyob rau hauv ntau yam xws li kev lag luam, tub rog thiab kev lag luam, tab sis nws yog tsuas yog siv nyob rau hauv cov nram qab no yam:
1. Kev sib txuas lus thiab optical networks
Cov khoom siv kho qhov muag sib xyaw yog cov khoom siv tseem ceeb kom paub txog kev kub ceev thiab lub peev xwm loj ntawm kev sib txuas lus kho qhov muag, suav nrog cov lus teb ceev ceev sib xyaw laser, waveguide grating array ntom wavelength division multiplexer, narrowband teb integrated photodetector, routing wavelength converter, ceev teb optical switching matrix, tsawg poob ntau yam nkag waveguide beam splitter thiab lwm yam.
2. Photonic computer
Lub npe hu ua photon computer yog lub khoos phis tawj uas siv lub teeb ua qhov sib kis ntawm cov ntaub ntawv. Photons yog bosons, uas tsis muaj hluav taws xob, thiab cov kab teeb ci tuaj yeem dhau los ua ke lossis hla tsis muaj kev cuam tshuam rau ib leeg, uas muaj peev xwm ua tau zoo ntawm kev ua tib yam zoo. Photonic computer kuj muaj qhov zoo ntawm cov ntaub ntawv loj cia muaj peev xwm, muaj zog tiv thaiv kev cuam tshuam, tsis tshua muaj kev xav tau rau ib puag ncig, thiab muaj zog ua txhaum cai. Cov khoom siv tseem ceeb tshaj plaws ntawm cov khoos phis tawj photonic yog cov hloov kho qhov muag thiab cov khoom siv kho qhov muag sib xyaw ua ke.
3. Lwm yam kev siv, xws li optical information processor, fiber optic sensor, fiber grating sensor, fiber optic gyroscope, thiab lwm yam.
