Rofea Optoelectronics Zvigadzirwa zvedu zvemhando yepamusoro uye zvemhando yepamusoro:
1. Nhevedzano yemifananidzo
2. Nhevedzano yeElectro-optic modulator
3. Nhevedzano yeLaser (chiedza)
4. Optical Amplifier Series
5. Zvigadzirwa zve microwave photonic link
6. Kuedzwa kweMaziso
Rofea Optoelectronics ine mabhenefiti makuru muindasitiri, akadai sekugadzirisa, kusiyana-siyana, magadzirirwo, kushanda zvakanaka, uye sevhisi yakanaka. Uye muna 2016 yakahwina chitupa chebhizinesi repamusoro-soro reBeijing, ine zvitupa zvakawanda zvepatenti, simba rakasimba, zvigadzirwa zvinotengeswa mumisika yemumba nekunze kwenyika, ine kushanda kwayo kwakasimba, kwepamusoro-soro kuti iwane rumbidzo kubva kuvashandisi vari kumba nekunze kwenyika!
Electro-optic modulator ndiyo chinhu chakakosha chekugadzirisa chiratidzo chelaser chinoramba chichienderera mberi uchishandisa data, radio frequency uye masaini ewachi. Maumbirwo akasiyana emodulator ane mabasa akasiyana. Kuburikidza ne optical modulator, simba remafungu echiedza rinogona kuchinjwa kwete chete, asiwo phase uye polarization state ye light wave inogona kugadziriswa. Electro-optic modulators dzinonyanya kushandiswa ndiMach-Zehnder intensity modulators uye phase modulators.
Rofea yakazvigadzira yega photodetector yakabatanidzwa photodiode uye low noise amplifier circuit, uku ichipa zvigadzirwa zvakasiyana-siyana, kune vashandisi vesainzi. Inopa sevhisi yekugadzirisa zvigadzirwa zvemhando yepamusoro, rutsigiro rwehunyanzvi uye sevhisi iri nyore mushure mekutengesa. Mutsetse wezvigadzirwa zvemazuva ano unosanganisira: analog signal photodetector ine amplification, gain adjustable photodetector, high speed photodetector, snow market detector (APD), balance detector, nezvimwewo.
Rofea inopa mamodule elaser akasimba uye akavimbika ekutaurirana kwefiber, optical fiber sensing, fiber optic gyro uye quantum communication. Drive circuit uye tembiricha control circuit zvakabatanidzwa mune imwe, kuti vashandisi vemayuniti ekutsvagisa kwesainzi vape divi. Chinhu chikuru
zvigadzirwa zvinosanganisira DEB laser light source, broadband light source, pulse light source, nezvimwewo.
optical amplifier chishandiso chinogamuchira chiedza chechiratidzo chekupinda uye chinoburitsa chiratidzo chekupinda chine simba repamusoro rekuona. Kazhinji, zvinopinda uye zvinobuda imalaser beams (kashoma dzimwe mhando dzemwenje), dzingave dzichipararira seGaussian beams munzvimbo yakasununguka kana mufiber.
Kuwedzerwa kwesimba kunoitika mune inonzi gain medium, iyo inofanirwa "kupombwa" (kureva, kupihwa simba) kubva kune imwe nzvimbo yekunze. Mazhinji ema optical amplifiers anopombwa ne optically kana ne electrically.
Rofea inonyanya kugadzira RF transmission field, iyo yazvino kuburitswa kwezvigadzirwa zveRF optical fiber transmission. Iyo RF fiber transmission module inochinja zvakananga chiratidzo cheRF cheanalog kuenda kune optical transceiver, ichichitumira kuburikidza ne optical fiber kusvika kumagumo anogamuchira,
uye wobva waishandura kuita RF signal mushure mekuchinja kwe photoelectric. Zvigadzirwa izvi zvinofukidza L, S, X, Ku nedzimwe frequency bands, uchishandisa compact metal casting shell, electromagnetic interference resistance yakanaka, wide working band, flatness yakanaka muband, inonyanya kushandiswa mu
antenna yekufamba-famba kwe microwave, chiteshi chekudzokorora, chiteshi chepasi chesatellite nedzimwe nzvimbo.
Zvishandiso zvefiber zvinochengetedza polarization zvakaita se laser inochengetedza polarization, fiber inochengetedza polarization, collimator inochengetedza polarization, y-waveguide modulator, polarization inochengetedza fiber, nezvimwewo zvinoshandiswa zvakanyanya muminda ye interferometer, gyroscope, fiber sensing,
nezvimwewo. Kuedzwa kwemidziyo iyi idanho rakakosha mukugadzirwa kwayo. Mushure memakore akawanda ekutsvaga nekugadzira, Rofea Optoelectronics yakaunganidza mhando dzakasiyana dzemhinduro dzekuyedza, kusanganisira chiedza chekuedza, laser driver, optical power meter, extinction ratio tester nezvimwe zvishandiso. Zvichienderana nezvinodiwa nevatengi, Rofea Optoelectronics inopa nzira imwe chete/mbiri yechiteshi uye multi-channel integrated test system yekuedza kugadzikana kwenguva refu, izvo zvinovandudza zvikuru kushanda zvakanaka kwekugadzira.
