Imiphumela yakamuva yocwaningo yama-organic photodetectors
Abacwaningi basungule futhi babonisa ama-photodetectors amasha aluhlaza azwela kakhulu futhi ahambisana nezindlela zokukhiqiza ze-CMOS. Ukufaka lezi zitholi zezithombe ezintsha kuzinzwa zesithombe ezihlanganisiwe ze-silicone kungaba usizo ezinhlelweni eziningi. Lezi...Funda kabanzi -
Umfutho wokuthuthukiswa kwenzwa ye-infrared muhle
Noma iyiphi into enezinga lokushisa elingaphezu kukaziro ophelele ikhipha amandla emkhathini ngendlela yokukhanya kwe-infrared. Ubuchwepheshe bezinzwa obusebenzisa imisebe ye-infrared ukukala amanani aphathekayo afanele bubizwa ngokuthi ubuchwepheshe bokuzwa kwe-infrared. Ubuchwepheshe bezinzwa ze-infrared bungenye ye-dev esheshayo...Funda kabanzi -
Isimiso se-Laser kanye nokusetshenziswa kwayo
I-Laser isho inqubo kanye nethuluzi lokukhiqiza imisebe yokukhanya ehlanganisiwe, e-monochromatic, ehambisanayo ngokukhuliswa kwemisebe evuselelwe kanye nempendulo edingekayo. Ngokuyisisekelo, ukukhiqizwa kwe-laser kudinga izinto ezintathu: “i-resonator,” “i-gain medium,” kanye “ne-pu...Funda kabanzi -
Iyini i-optics ehlanganisiwe?
Umqondo wokuhlanganisa optics wabekwa phambili nguDkt. Miller weBell Laboratories ngo-1969. I-Integrated optics iyisihloko esisha esicwaninga futhi sithuthukise amadivaysi okubona kanye namasistimu edivaysi kagesi eyingxubevange esebenzisa izindlela ezididiyelwe ngesisekelo se-optoelectronics kanye ne-microelectronics. Th...Funda kabanzi -
Isimiso sokupholisa i-laser kanye nokusetshenziswa kwayo kuma-athomu abandayo
Isimiso sokupholisa nge-laser nokusetshenziswa kwako kuma-athomu abandayo Ku-athomu ebandayo ye-athomu, umsebenzi omningi wokuhlola udinga ukulawula izinhlayiya (ama-athomu e-ionic avalelwe, njengamawashi e-athomu), ukuwanciphisa, nokuthuthukisa ukunemba kokulinganisa. Ngokuthuthukiswa kobuchwepheshe be-laser, i-laser coo...Funda kabanzi -
Isingeniso kuma-photodetectors
I-photodetector iyisisetshenziswa esiguqula amasignali okukhanya abe amasignali kagesi. Kusithwebuli sesithombe se-semiconductor, inkampani yenethiwekhi ekhiqizwe isithombe ejatshuliswe yi-photon yesigameko ingena kwisekethe yangaphandle ngaphansi kwe-voltage yokuchema esetshenzisiwe bese yenza i-photocurrent elinganisekayo. Ngisho nezimpendulo eziphezulu...Funda kabanzi -
Iyini i-laser esheshayo
A. Umqondo we-ultrafast lasers Ama-laser asheshayo ngokuvamile abhekisela kuma-lases akhiyiwe emodi esetshenziselwa ukukhipha amapulse amafushane kakhulu, isibonelo, ubude besikhathi se-femtosecond noma picosecond. Igama elinembe kakhudlwana kungaba i-ultrashort pulse laser. Ama-laser e-Ultrashort pulse cishe acishe abe ama-mode-locked lasers, kodwa ...Funda kabanzi -
Umqondo nokuhlukaniswa kwama-nanolasers
I-Nanolaser iwuhlobo lwedivayisi encane ne-nano eyenziwe ngama-nanomaterials njenge-nanowire njenge-resonator futhi ingakhipha i-laser ngaphansi kwe-photoexcitation noma i-excitation kagesi. Usayizi wale laser uvame ukuba ngamakhulu ama-microns noma amashumi ama-microns, futhi ububanzi bufika ku-nanometer ...Funda kabanzi -
I-spectroscopy ye-laser-induced breakdown
I-Laser-Induced Breakdown Spectroscopy (LIBS), eyaziwa nangokuthi i-Laser-Induced Plasma Spectroscopy (LIPS), iyindlela yokuthola i-spectral esheshayo. Ngokugxilisa i-laser pulse ene-high density yamandla ebusweni bethagethi yesampula ehloliwe, i-plasma ikhiqizwa ukuvuswa kwe-ablation, futhi ...Funda kabanzi -
Yiziphi izinto ezisetshenziswayo ezijwayelekile zokwenza i-optical element?
Yiziphi izinto ezivamile ezisetshenziselwa umshini we-optical element? Izinto ezisetshenziswa kakhulu ekucubunguleni izinto ezibonakalayo ikakhulukazi zifaka ingilazi ebonakalayo ejwayelekile, amapulasitiki okukhanya, namakristalu okukhanya. Ingilazi ye-Optical Ngenxa yokufinyelela kwayo kalula kokufana okuphezulu kokudluliswa okuhle, kuye kwaba ...Funda kabanzi -
Iyini imoduli yokukhanya yendawo?
I-Spatial light modulator isho ukuthi ngaphansi kokulawulwa okusebenzayo, ingakwazi ukuguqula amanye amapharamitha enkambu yokukhanya ngokusebenzisa ama-molecule e-crystal ewuketshezi, njengokushintsha i-amplitude yenkundla yokukhanya, ukulungisa isigaba ngenkomba ye-refractive, ukulungisa isimo se-polarization ngokuzungezisa ...Funda kabanzi
