Rofea Optoelectronics imapereka zinthu zathu zapamwamba komanso zapamwamba za photonics ndi optoelectronics.

Rofea Optoelectronics Zogulitsa zathu zapamwamba komanso zapamwamba:
1. Mndandanda wa zida zowunikira zithunzi
2. Mndandanda wa ma modulator a Electro-optic
3. Mndandanda wa laser (gwero la kuwala)
4. Mndandanda wa Amplifier ya Kuwala
5. Zogulitsa za microwave photonic link
6. Mayeso Owona

Rofea Optoelectronics ili ndi ubwino waukulu mumakampani, monga kusintha, kusiyanasiyana, kufotokozera, kugwira ntchito bwino, ndi ntchito yabwino kwambiri. Ndipo mu 2016 idapambana satifiketi yamakampani apamwamba ku Beijing, ili ndi ziphaso zambiri za patent, mphamvu yamphamvu, zinthu zogulitsidwa m'misika yakunja ndi kunja, ndi magwiridwe ake okhazikika komanso apamwamba kwambiri kuti ipambane ulemu wa ogwiritsa ntchito kunyumba ndi kunja!

Electro-optic modulator ndiye chida chofunikira kwambiri chosinthira chizindikiro cha laser chopitilira pogwiritsa ntchito deta, ma frequency a wailesi ndi ma signal a wotchi. Kapangidwe kosiyanasiyana ka modulator kali ndi ntchito zosiyanasiyana. Kudzera mu optical modulator, sikuti mphamvu ya mafunde a kuwala yokha ingasinthidwe, komanso momwe gawo ndi polarization ya mafunde a kuwala zimatha kusinthidwa. Ma electro-optic modulators omwe amagwiritsidwa ntchito kwambiri ndi Mach-Zehnder intensity modulators ndi phase modulators.

Rofea idapanga yokha chowunikira zithunzi cholumikizidwa ndi chowunikira phokoso lotsika, pomwe ikupereka zinthu zosiyanasiyana, kwa ogwiritsa ntchito kafukufuku wasayansi. Imapereka ntchito yabwino kwambiri yosinthira zinthu, chithandizo chaukadaulo komanso ntchito yabwino yogulitsa pambuyo pogulitsa. Mzere wazinthu zomwe zilipo pano umaphatikizapo: chowunikira zithunzi cha analog chokhala ndi amplification, chowunikira chosinthika cha gain, chowunikira zithunzi cha liwiro lalikulu, chowunikira msika wa chipale chofewa (APD), chowunikira bwino, ndi zina zotero.

Rofea imapereka ma module okhazikika komanso odalirika a laser kuti azitha kulumikizana ndi fiber optical, optical fiber sensor, fiber optic gyro ndi quantum communication. Drive circuit ndi temperature control circuit zophatikizidwa mu imodzi, kuti ogwiritsa ntchito mayunitsi ofufuza asayansi apereke mbali.
Zinthu monga DEB laser light source, broadband light source, pulse light source, ndi zina zotero.

Chojambulira kuwala ndi chipangizo chomwe chimalandira kuwala kwa chizindikiro cholowera ndikupanga chizindikiro chotulutsa ndi mphamvu yayikulu yowunikira. Kawirikawiri, zolowetsa ndi zotulutsa zimakhala kuwala kwa laser (kawirikawiri mitundu ina ya kuwala), mwina zimafalikira ngati kuwala kwa Gaussian pamalo omasuka kapena mu ulusi.
Kukulitsa kumeneku kumachitika mu njira yotchedwa gain medium, yomwe imayenera "kupompedwa" (kutanthauza, kupatsidwa mphamvu) kuchokera ku gwero lakunja. Ma amplifiers ambiri a kuwala amapompedwa ndi kuwala kapena magetsi.

Rofea imadziwika kwambiri pa gawo lotumizira ma RF, kutulutsidwa kwaposachedwa kwa zinthu zingapo zotumizira ma RF optical fiber. Gawo lotumizira ma RF fiber limasinthira mwachindunji chizindikiro cha analog RF kupita ku transceiver ya optical, ndikuchitumiza kudzera mu fiber yowunikira mpaka kumapeto,
kenako n’kuisintha kukhala chizindikiro cha RF pambuyo posintha kuwala kwa dzuwa. Zogulitsazi zimaphatikizapo ma band a L, S, X, Ku ndi ma frequency ena, pogwiritsa ntchito chipolopolo chachitsulo chopopera, kukana bwino kusokonezedwa ndi ma electromagnetic, band yogwira ntchito bwino, kusalala bwino m’band, komwe kumagwiritsidwa ntchito kwambiri mu
Antena yolumikizira ma microwave delay line multimotion, siteshoni yobwerezabwereza, siteshoni yapansi panthaka ya satellite ndi malo ena.

Zipangizo zosungira ulusi monga laser yosunga polarization, ulusi wosunga polarization, collimator yosunga polarization, modulator ya y-waveguide, ulusi wosunga polarization, ndi zina zotero zimagwiritsidwa ntchito kwambiri m'magawo a interferometer, gyroscope, fiber sensing,
ndi zina zotero. Kuyesa zipangizozi ndi gawo lofunika kwambiri pakupanga. Pambuyo pa zaka zambiri zofufuza ndi kupanga, Rofea Optoelectronics yasonkhanitsa mayankho osiyanasiyana oyesera, kuphatikizapo gwero la kuwala koyesera, dalaivala wa laser, mita yamagetsi owonera, choyezera kuchuluka kwa kutayika ndi zida zina. Malinga ndi zosowa za makasitomala, Rofea Optoelectronics imapereka njira imodzi/kawiri ya siteshoni ndi njira yoyesera yolumikizidwa ya njira zambiri kuti iwonetse kukhazikika kwa nthawi yayitali, zomwe zimathandizira kwambiri magwiridwe antchito opanga.
