Umqondo we-integrated optics wethulwa nguDkt. Miller waseBell Laboratories ngo-1969. I-integrated optics yisifundo esisha esihlola futhi sithuthukise amadivayisi optical kanye nezinhlelo zedivayisi ye-electronic optical hybrid esebenzisa izindlela ezihlanganisiwe ngokusekelwe ku-optoelectronics kanye ne-microelectronics. Isisekelo semfundiso yenkolo se-integrated optics yi-optics kanye ne-optoelectronics, ehilela i-wave optics kanye ne-information optics, i-nonlinear optics, i-semiconductor optoelectronics, i-crystal optics, i-thin film optics, i-guided wave optics, i-coupled mode kanye ne-parametric interaction theory, amadivayisi nezinhlelo ze-thin film optical waveguide. Isisekelo sezobuchwepheshe ikakhulukazi ubuchwepheshe befilimu encane kanye nobuchwepheshe be-microelectronics. Insimu yesicelo se-integrated optics ibanzi kakhulu, ngaphezu kokuxhumana kwe-optical fiber, ubuchwepheshe bokubona i-optical fiber, ukucubungula ulwazi lwe-optical, i-optical computer kanye ne-optical storage, kunezinye izinkambu, njengocwaningo lwesayensi yezinto ezibonakalayo, izinsimbi zokubona, ucwaningo lwe-spectral.
Okokuqala, izinzuzo zokukhanya ezihlanganisiwe
1. Ukuqhathaniswa nezinhlelo zamadivayisi optical ezihlukile
Idivayisi ye-Discrete optical uhlobo lwedivayisi ye-optical exhunywe epulatifomu enkulu noma esisekelweni se-optical ukuze kwakheke uhlelo lwe-optical. Usayizi wesistimu ungo-1m2, kanti ubukhulu bomsebe bungaba ngu-1cm. Ngaphezu kobukhulu bawo obukhulu, ukuhlanganiswa nokulungiswa nakho kunzima kakhulu. Uhlelo lwe-optical oluhlanganisiwe lunezinzuzo ezilandelayo:
1. Amaza okukhanya asakazeka kuma-waveguide abonakalayo, futhi amaza okukhanya kulula ukuwalawula nokugcina amandla awo.
2. Ukuhlanganiswa kuletha indawo eqinile. Njengoba kushiwo ngenhla, ama-optics ahlanganisiwe alindele ukwenza amadivayisi amaningana ku-substrate efanayo, ngakho-ke azikho izinkinga zokuhlanganiswa ezinazo ama-optics ahlukene, ukuze inhlanganisela ikwazi ukuzinza, ukuze ikwazi nokuzivumelanisa nezimo zemvelo njengokudlidliza kanye nokushisa.
(3) Usayizi wedivayisi kanye nobude bokuxhumana kuyafinyezwa; Ama-elekthronikhi ahlobene nawo asebenza ngama-voltage aphansi.
4. Ubuningi bamandla aphezulu. Ukukhanya okudluliselwa eceleni kwe-waveguide kuvinjelwe endaweni encane yendawo, okuholela ekubunjweni kwamandla aphezulu okukhanya, okulula ukufinyelela emikhawulweni yokusebenza kwedivayisi edingekayo futhi kusebenze ngemiphumela yokukhanya engeyona eye-linear.
5. Ama-optics ahlanganisiwe ngokuvamile ahlanganiswe ku-substrate yesilinganiso samasentimitha, encane ngobukhulu futhi inesisindo esincane.
2. Ukuqhathaniswa nezifunda ezihlanganisiwe
Izinzuzo zokuhlanganiswa kwe-optical zingahlukaniswa zibe izici ezimbili, esinye siwukufaka esikhundleni sohlelo lwe-elekthronikhi oluhlanganisiwe (isekethe ehlanganisiwe) ngohlelo lwe-optical oluhlanganisiwe (isekethe ehlanganisiwe ye-optical); Esinye sihlobene ne-optical fiber kanye ne-dielectric plane optical waveguide eqondisa igagasi lokukhanya esikhundleni sentambo noma ikhebula le-coaxial ukuze kudluliselwe isignali.
Endleleni ehlanganisiwe ye-optical, izakhi ze-optical zakhiwa ku-substrate ye-wafer futhi zixhunywe yi-optical waveguides ezakhiwe ngaphakathi noma ebusweni be-substrate. Indlela ehlanganisiwe ye-optical, ehlanganisa izakhi ze-optical ku-substrate efanayo ngesimo sefilimu encane, iyindlela ebalulekile yokuxazulula i-miniaturization yesistimu yokuqala ye-optical nokuthuthukisa ukusebenza okuphelele. Idivayisi ehlanganisiwe inezinzuzo zobukhulu obuncane, ukusebenza okuzinzile nokuthembekile, ukusebenza kahle okuphezulu, ukusetshenziswa kwamandla aphansi kanye nokusetshenziswa okulula.
Ngokuvamile, izinzuzo zokushintsha amasekethe ahlanganisiwe ngamasekethe ahlanganisiwe e-optical zifaka phakathi i-bandwidth eyandisiwe, i-multiplexing yokuhlukaniswa kwe-wavelength, ukushintshashintsha kwe-multiplex, ukulahlekelwa okuncane kokuxhuma, usayizi omncane, isisindo esincane, ukusetshenziswa kwamandla aphansi, ukugcinwa okuhle kokulungiswa kwe-batch, kanye nokuthembeka okuphezulu. Ngenxa yokusebenzisana okuhlukahlukene phakathi kokukhanya nezinto, imisebenzi emisha yedivayisi ingabonakala ngokusebenzisa imiphumela ehlukahlukene yomzimba efana nomphumela we-photoelectric, umphumela we-electro-optical, umphumela we-acousto-optical, umphumela we-magneto-optical, umphumela we-thermo-optical njalo njalo ekwakhiweni kwendlela ehlanganisiwe ye-optical.
2. Ucwaningo kanye nokusetshenziswa kwe-optics ehlanganisiwe
I-Integrated optics isetshenziswa kabanzi emikhakheni eyahlukene njengemboni, ezempi kanye nomnotho, kodwa isetshenziswa kakhulu kulezi zici ezilandelayo:
1. Amanethiwekhi okuxhumana kanye nokukhanya
Amadivayisi ahlanganisiwe e-Optical ayihadiwe eyisihluthulelo sokufeza amanethiwekhi okuxhumana e-optical asheshayo futhi anomthamo omkhulu, kufaka phakathi umthombo we-laser ohlanganisiwe we-response high-speed, 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 nokunye.
2. Ikhompyutha ye-Photonic
Ikhompyutha ebizwa ngokuthi i-photon iyikhompyutha esebenzisa ukukhanya njengendlela yokudlulisa ulwazi. Ama-photon angama-boson, angenawo amandla kagesi, futhi imisebe yokukhanya ingadlula ngokulingana noma inqamule ngaphandle kokuthintana, enekhono elingokwemvelo lokucubungula okukhulu okuhambisanayo. Ikhompyutha ye-Photonic nayo inezinzuzo zomthamo omkhulu wokugcina ulwazi, ikhono eliqinile lokulwa nokuphazamiseka, izidingo eziphansi zezimo zemvelo, kanye nokubekezelelana kwamaphutha okunamandla. Izingxenye eziyisisekelo zokusebenza kwamakhompyutha e-photonic yizinkinobho ze-optical ezihlanganisiwe kanye nezingxenye ze-optical logic ezihlanganisiwe.
3. Ezinye izinhlelo zokusebenza, njengeprosesa yolwazi lwe-optical, inzwa ye-fiber optic, inzwa ye-fiber grating, i-fiber optic gyroscope, njll.
