Ingcamango ye-integrated optics yavezwa nguGqr. Miller weBell Laboratories ngo-1969. I-integrated optics sisifundo esitsha esifunda kwaye siphuhlise izixhobo ze-optical kunye neenkqubo ze-elektroniki ze-optical hybrid zisebenzisa iindlela ezidibeneyo ngokusekelwe kwi-optoelectronics kunye ne-microelectronics. Isiseko sethiyori se-integrated optics yi-optics kunye ne-optoelectronics, equka i-wave optics kunye ne-information optics, i-nonlinear optics, i-semiconductor optoelectronics, i-crystal optics, i-thin film optics, i-guided wave optics, i-coupled mode kunye ne-parametric interaction theory, izixhobo kunye neenkqubo ze-thin film optical waveguide. Isiseko setekhnoloji ikakhulu yitekhnoloji yefilimu encinci kunye netekhnoloji ye-microelectronics. Intsimi yesicelo se-integrated optics ibanzi kakhulu, ukongeza kunxibelelwano lwe-optical fiber, itekhnoloji yokubona i-optical fiber, ukucutshungulwa kolwazi lwe-optical, ikhompyutha ye-optical kunye nokugcinwa kwe-optical, kukho eminye imimandla, efana nophando lwesayensi yezinto, izixhobo ze-optical, uphando lwe-spectral.
Okokuqala, iingenelo ezidibeneyo zokukhanya
1. Uthelekiso neenkqubo zezixhobo ezibonakalayo ezizimeleyo
Isixhobo se-optical esingabonakaliyo luhlobo lwesixhobo se-optical esixhonywe kwiqonga elikhulu okanye kwisiseko se-optical ukwenza inkqubo ye-optical. Ubungakanani benkqubo bumalunga ne-1m2, kwaye ubukhulu be-beam bumalunga ne-1cm. Ukongeza kubukhulu bayo obukhulu, ukuhlanganiswa kunye nokulungiswa nako kunzima ngakumbi. Inkqubo ye-optical edibeneyo inezibonelelo ezilandelayo:
1. Amaza okukhanya asasazeka kwiindlela zokukhanya ezibonakalayo, kwaye amaza okukhanya kulula ukuwalawula nokugcina amandla awo.
2. Ukudibanisa kuzisa indawo ezinzileyo. Njengoko kukhankanyiwe apha ngasentla, ii-optics ezidibeneyo zilindele ukwenza izixhobo ezininzi kwi-substrate enye, ngoko ke akukho ngxaki zokudibanisa ezifana nee-optics ezihlukeneyo, ukuze indibaniselwano ikwazi ukuzinza, ukuze ikwazi ukuzivumelanisa neemeko zokusingqongileyo ezifana nokungcangcazela kunye nobushushu.
(3) Ubungakanani besixhobo kunye nobude bokusebenzisana bufinyeziwe; Izixhobo ze-elektroniki ezinxulumene nazo zisebenza kwiivoltheji eziphantsi.
4. Ubuninzi bamandla aphezulu. Ukukhanya okudluliselwa ecaleni kwe-waveguide kuxhomekeke kwindawo encinci yendawo, nto leyo ebangela ubuninzi bamandla e-optical, okulula ukufikelela kwimida yokusebenza kwesixhobo esifunekayo kwaye kusebenze ngeziphumo ze-optical ezingezizo ezomgca.
5. ii-optics ezidibeneyo zihlala zidityaniswe kwi-substrate yesikali seesentimitha, encinci ngobukhulu kwaye ilula ngobunzima.
2. Uthelekiso neesekethe ezidibeneyo
Iingenelo zokudibanisa i-optical zinokwahlulwa zibe ziinkalo ezimbini, enye kukutshintsha inkqubo ye-elektroniki edibeneyo (isekethe edibeneyo) ngenkqubo ye-optical edibeneyo (isekethe edibeneyo ye-optical); Enye inxulumene ne-optical fiber kunye ne-dielectric plane optical waveguide ekhokela i-light wave endaweni ye-wire okanye i-coaxial cable ukuhambisa isignali.
Kwindlela edibeneyo yokukhanya, izinto ezibonakalayo zenziwa kwi-substrate ye-wafer kwaye ziqhagamshelwe zii-waveguides ze-optical ezenziwe ngaphakathi okanye kumphezulu we-substrate. Indlela edibeneyo yokukhanya, edibanisa izinto ezibonakalayo kwi-substrate efanayo ngendlela yefilimu encinci, yindlela ebalulekileyo yokusombulula i-miniaturization yenkqubo yokuqala yokukhanya kunye nokuphucula ukusebenza ngokubanzi. Isixhobo esidibeneyo sineenzuzo zobukhulu obuncinci, ukusebenza okuzinzileyo nokuthembekileyo, ukusebenza kakuhle okuphezulu, ukusetyenziswa kwamandla aphantsi kunye nokusetyenziswa okulula.
Ngokubanzi, iingenelo zokutshintsha iisekethe ezidityanisiweyo ngeesekethe ze-optical ezidityanisiweyo ziquka ukwanda kwe-bandwidth, i-multiplexing yokwahlulahlula ubude be-wavelength, i-multiplex switching, i-small coupling loss, ubungakanani obuncinci, ubunzima obulula, ukusetyenziswa kwamandla aphantsi, ukulungiswa kakuhle kwebhetshi, kunye nokuthembeka okuphezulu. Ngenxa yokusebenzisana okwahlukeneyo phakathi kokukhanya kunye nezinto, imisebenzi emitsha yesixhobo inokufunyanwa ngokusebenzisa iziphumo ezahlukeneyo zomzimba ezifana ne-photoelectric effect, i-electro-optical effect, i-acousto-optical effect, i-thermo-optical effect njalo njalo kwisakhiwo sendlela ye-optical edityanisiweyo.
2. Uphando kunye nokusetyenziswa kwe-optics edibeneyo
I-Integrated optics isetyenziswa kakhulu kwiinkalo ezahlukeneyo ezifana nezoshishino, ezomkhosi kunye noqoqosho, kodwa isetyenziswa kakhulu kwezi zinto zilandelayo:
1. Unxibelelwano kunye neenethiwekhi ze-optical
Izixhobo ezidityanisiweyo zezona zixhobo ziphambili zokuphumeza iinethiwekhi zonxibelelwano lwe-optical ezikhawulezayo nezinomthamo omkhulu, kubandakanya umthombo we-laser odibeneyo wempendulo ephezulu, i-waveguide grating array dense wavelength division multiplexer, i-narrowband response integrated photodetector, i-routing wavelength converter, i-fast response optical switching matrix, i-low loss multiple access waveguide beam splitter njalo njalo.
2. Ikhompyutha yeFotoniki
Ikhompyutha ebizwa ngokuba yi-photon yikhompyutha esebenzisa ukukhanya njengendlela yokudlulisela ulwazi. Ii-photon zii-bosons, ezingenayo itshaja yombane, kwaye imisebe yokukhanya inokudlula ngaxeshanye okanye inqamleze ngaphandle kokuchaphazelana, enobuchule bendalo bokucubungula kakuhle okufanayo. Ikhompyutha ye-Photonic ikwanazo neengenelo zomthamo omkhulu wokugcina ulwazi, amandla aqinileyo okulwa nokuphazamiseka, iimfuno eziphantsi kwiimeko zokusingqongileyo, kunye nokunyamezelana okunamandla kweempazamo. Ezona zinto zibalulekileyo ezisebenzayo kwiikhompyutha ze-photonic ziiswitshi ze-optical ezidibeneyo kunye nezixhobo ze-logic ze-optical ezidibeneyo.
3. Ezinye izicelo, ezifana neprosesa yolwazi lwe-optical, i-fiber optic sensor, i-fiber grating sensor, i-fiber optic gyroscope, njl.njl.
