I-polarization ye-electro-opticUlawulo lufezekisiwe yi-FebtoseCond Laser kunye nemodareyitha yekristale
Abaphandi eJamani baphuhlise indlela yeNovers yolawulo lweSignali ngokudibanisa i-FebtoseCond Ell kunye ne-cystal yolweloImoDolo ye-electro-optic. Ngokuxhonywa kwe-crystal ye-crystal ye-curistal kwi-waveguide, ulawulo lwe-electro-olical lwendawo yePolicarazation ifezekisiwe. Itekhnoloji ivula amathuba amatsha apheleleyo kwizixhobo ezisekwe kwizixhobo ze-Chip kunye nesekethe entsokothileyo eshukumayo esebenzisa itekhnoloji yokubhala i-Febtosend. IQela loPhando lineenkcukacha zendlela abazenza ngayo iipleyiti ze-fed fred waveegides. Xa i-voltage isetyenziswa kwikristali yolwelo, iimolethi zekristale yolwelo ijikeleze, etshintsha imeko yokugcwala kokukhanya okuphezulu kwi-waveguide. Kuvavanyo olwenziweyo, abaphandi baziphose ngempumelelo ngokupheleleyo ukubonakala kokukhanya kumaza amabini abonakalayo abonakale (umzobo 1).
Ukudibanisa iitekhnoloji ezimbini eziphambili zokufezekisa inkqubela phambili ye-3D ye-phetotonic yesipho
Ukukwazi kwe-FebtoseCond Lasers ukuba bhala ngokuthe ngqo kumxholo, kunokuba ubuchwepheshele nje, bubenza ukuba babe netekhnoloji yokubonisa inani le-chip enye. Itekhnoloji isebenza ngokugxininisa i-Laser ye-Laser ePhakamileyo ngaphakathi kwento ebonakalayo. Xa ukukhanya okuqinileyo kufikelela kwinqanaba elithile, i-goam itshintsha iipropathi zezinto ngendlela yalo yesicelo, njengepeni kunye ne-PICS ECORCY.
IQela loPhando lidityaniswe neendlela ezimbini ezisisiseko ze-photon zokufaka ungqimba lweekristali zolwelo kwi-waveguide. Njengoko i-beam ihamba nge-wapeguide nangekristali yolwelo, iSigaba kunye nokungasebenzi kwe-Beam Guqula kube kanye kusetyenziswe intsimi yombane. Emva koko, i-Bheam yeMemodi iya kuqhubeka nokusasaza inxalenye yesibini ye-WaveGuide, ngaloo ndlela ifezekisa usulelo losulelo olubonakalayo kunye neempawu zemodyuli. Itekhnoloji ye-hybrid edibanisa iitekhnoloji ezimbini zikwenza ukuba izibonelelo zobabini: Kwelinye icala, ukuxinana okuphezulu kokugxininisa okukokwazi, kwelinye icala, uhlengahlengiso oluphezulu lwekristali yolwelo. Olu phando luvula iindlela ezintsha zokusebenzisa iipropathi zekristali yolwelo yokufaka i-wavegagides kumthamo wezixhobo njengokoiimodyulikubaIzixhobo ze-Photonic.
Umzobo 1 Abaphandi abangena kwi-crystal ye-crystal ye-wavegadis eyenziwe ngokubhala ngokuthe ngqo, kwaye isixhobo esine-hybrid esine-hybrid sinokusetyenziselwa ukutshintsha ukuguquguquka komgangatho wokukhanya
Isicelo kunye nezibonelelo zekristali yolwelo kwi-phytosecond lase-FebtoseCond LaveGeide
NangonaUkunyanzelwa kwemozuluKwi-phytosecond yaseFebtosencond WapeGegades ngaphambili yayifezekisiwe ngokusebenzisa ukufudumeza kwendawo kumakhonkco, kolu phando, ipoliza yalawulwa ngokuthe ngqo ngokusebenzisa amakristali olwelo. "Indlela yethu inezibonelelo ezininzi ezinokubakho: Ukusetyenziswa kwamandla okuthoba, amandla okwenza umntu wakhubeka ngokuzimeleyo, kwaye kunciphise ukuphazamiseka phakathi kwe-Avegagides," Qaphela abaphandi. Ukuvavanya ukusebenza kwefowuni, iqela laguqa i-laser kwi-wapegue kwaye yamongamela ukukhanya kwe-voltage esetyenzisiweyo kwi-crystal yolwelo. Iinguqulelo zokulinganisa ezibonisiweyo kwimveliso ziyahambelana nolindelo lwe-theoretical. Abaphandi bafumanise ukuba emva kokuba ikristale yolwelo idityaniswe ne-WaveGuide, iimpawu zemodyuli zekristali yolwelo zihlala zingaguqukanga. Abaphandi bagxininisa ukuba isifundo bubungqina bengcinga, ngenxa yoko kusekho umsebenzi omninzi ekufuneka wenziwe ngaphambi kokuba itekhnoloji ingasetyenziswa. Umzekelo, izixhobo ezikhoyo ngoku ezi zixhobo zangoku zenziwe ngalo lonke ixesha, ke iqela lisebenzela ukufezekisa ulawulo oluzimeleyo lwe-waveguide.
