izisombululo ze-standard intensity modulator

Imodyuli yokuqina

Njenge-modulator esetyenziswa kakhulu kwiinkqubo ezahlukeneyo ze-optical, ukwahluka kwayo kunye nokusebenza kwayo kunokuchazwa njengento eninzi neyinkimbinkimbi. Namhlanje, ndikulungiselele izisombululo ezine ze-standard intensity modulator: izisombululo ze-mechanical, izisombululo ze-electro-optical, i-Acousto-optic scheme, kunye ne-liquid crystal scheme.

Isisombululo seMishini

I-mechanical intensity modulator yeyona modulator inamandla yokuqala nesetyenziswa kakhulu. Umgaqo kukutshintsha umlinganiselo we-s-light ukuya kwi-hazard ekukhanyeni oku-polarized ngokujikeleza ipleyiti ye-half-wave kunye nokwahlula ukukhanya nge-analyzer. Ukususela kuhlengahlengiso lokuqala lwesandla ukuya kwi-automated kakhulu kunye nokuchaneka okuphezulu kwanamhlanje, iintlobo zemveliso kunye nophuhliso lwesicelo ziye zavuthwa. I-Fortune Technology inika abathengi uthotho lolawulo lombane okanye lwesandla kunye nokuxhasa izinto ze-polarized kunye nezinye iimveliso ezinxulumene noko ukuhlangabezana nokusetyenziswa okwahlukileyo. Iimfuno zoyilo:

isisombululo se-electro-optical

I-electro-optical intensity modulator inokutshintsha i-intensity okanye i-amplitude yokukhanya oku-polarized. Lo mgaqo usekelwe kwi-Pockels effect ye-electro-optical crystal. Emva kokuba i-polarized light beam idlule kwi-electro-optic crystal esetyenziswa kunye ne-electric field, imeko ye-polarization iyatshintshwa kwaye yahlulwe ngokukhetha yi-analyzer. I-intensity yokukhanya okukhutshiweyo inokulawulwa ngokutshintsha i-electric field intensity, kwaye umda onyukayo/owayo womyalelo we-ns unokufezekiswa. Ixhomekeke kwiminyaka yayo yeenzuzo kwicandelo le-electro-optic crystals, i-Fortune Technology iqalise uthotho lwee-electro-optic intensity modulators ezifana nee-high-speed shutters, ezibonelela abathengi ngezisombululo ezivuthiweyo nezinokwenziwa ngokwezifiso.

Iprojekthi yeSandi nokukhanya

I-modulator ye-acousto-optic ingasetyenziswa njenge-modulator ye-intensity. Ukutshintsha ukusebenza kwe-diffraction kunokulawula amandla okukhanya kwe-0th order kunye ne-1st order light ukuze kufezekiswe injongo yokulungisa i-intensity yokukhanya. I-Acousto-optic golden gate (i-optical attenuator) ineempawu zesantya sokuguquguquka esikhawulezayo kunye nomlinganiselo womonakalo ophezulu. I-Fortune Technology inokubonelela ngee-modulator ze-acousto-optic intensity ezine-debrids zomonakalo ezidlula i-1GW/cm2 kunye ne-scattering ephantsi. Inokubonelela abathengi ngoyilo lwesisombululo esingcono ngokwesantya sokuguquguquka, ubude be-wavelength, ububanzi be-beam, umlinganiselo wokuphela, kunye nezinye izalathisi ezifunekayo kumthengi.

Isisombululo se-LCD

Izixhobo zekristale yolwelo zihlala zisetyenziswa njengeepleyiti zamaza eziguquguqukayo okanye izihluzi ezinokuhlengahlengiswa. Ukongeza izinto ezithile zepolarizing kwiziphelo ezimbini zeseli yekristale yolwelo apho kusetyenziswa khona i-drive voltage kungenziwa i-liquid crystal shutter okanye i-variable attenuator. Imveliso ine-aperture ecacileyo—iimpawu ezifana nokuthembeka okukhulu nokuphezulu.

I-Beijing Rofea Optoelectronics Co., Ltd. ekwi "Silicon Valley" yaseTshayina – iBeijing Zhongguancun, lishishini elinobuchwepheshe obuphezulu elizinikele ekukhonzeni amaziko ophando asekhaya nangaphandle, amaziko ophando, iiyunivesithi kunye nabasebenzi bophando lwezesayensi kwishishini. Inkampani yethu ibandakanyeka kakhulu kuphando oluzimeleyo nophuhliso, uyilo, imveliso, ukuthengiswa kweemveliso ze-optoelectronic, kwaye ibonelela ngezisombululo ezintsha kunye neenkonzo zobungcali, ezenzelwe wena kubaphandi bezesayensi kunye neenjineli zemizi-mveliso. Emva kweminyaka yokuvelisa izinto ezintsha ngokuzimeleyo, yenze uthotho lweemveliso ze-photoelectric ezityebileyo nezigqibeleleyo, ezisetyenziswa kakhulu kumashishini kamasipala, emkhosini, kwezothutho, kumandla ombane, kwezemali, kwimfundo, kwezonyango nakwamanye amashishini.
