Rof Electro-optic modulator EOM LiNbO3 Intensity Modulator

Electro-optic modulatorndiye chida chofunikira kwambiri chosinthira chizindikiro cha laser mosalekeza pogwiritsa ntchito ma data, ma frequency a wailesi ndi ma wotchi. Mitundu yosiyanasiyana ya ma modulator imakhala ndi ntchito zosiyanasiyana. Kupyolera mu optical modulator, osati mphamvu ya kuwala kwa mafunde angasinthidwe, komanso gawo ndi polarization mkhalidwe wa mafunde a kuwala akhoza kusinthidwa. Ma modulators omwe amagwiritsidwa ntchito kwambiri ndi ma electro-optic ndi Mach-Zehndermphamvu modulatorsndigawo modulators.

TheLiNbO3 intensity modulatorimagwiritsidwa ntchito kwambiri pamakina olumikizirana othamanga kwambiri, laser sensing ndi makina a ROF chifukwa chakuchita bwino kwa electro-optic. Mndandanda wa R-AM wotengera kapangidwe ka MZ kankha-chikoka ndi kapangidwe ka X-kudula, uli ndi mawonekedwe okhazikika athupi ndi mankhwala, omwe angagwiritsidwe ntchito poyesera ma labotale ndi machitidwe a mafakitale.

Mtundu wa modulator
Kutalika: 850nm/1064nm/1310nm/1550nm
Bandwidth: 10GHz/20GHz/40GHz
Zina: High ER Intensity Modulator/CascadingModulator ya MZ/Dual-parallel MZ Modulator

Mbali:
Kutayika kochepa kolowetsa
Low theka-voltage
Kukhazikika kwakukulu

Ntchito:
Machitidwe a ROF
Kugawa makiyi a Quantum
Makina owonera laser
Kusintha kwa gulu la mbali

Zofunikira pakuwonongeka kwakukulu
1. Makina osinthira makina ayenera kukhala ndi chiwopsezo chambiri. Makhalidwe a makina osinthira amasankha kuti chiŵerengero cha kuzimiririka kwakukulu chikwaniritsidwe.
2. Polarization ya kuwala kolowera modulator iyenera kusamalidwa. Ma modulators amakhudzidwa ndi polarization. Polarization yoyenera imatha kupititsa patsogolo chiwopsezo cha 10dB. Muzoyesa za labu, nthawi zambiri wowongolera polarization amafunikira.
3. Olamulira atsankho oyenera. Pakuyesa kwathu kwa DC extinction ratio, chiŵerengero cha kutha kwa 50.4dB chakwaniritsidwa. Pomwe zidziwitso za makina opanga ma module amangolemba 40dB. Chifukwa cha kusinthaku ndikuti ma modulators ena amasuntha mwachangu kwambiri. Rofea R-BC-ALIYENSE owongolera kukondera amasintha voteji ya tsankho pa sekondi imodzi iliyonse kuti atsimikizire kuyankha mwachangu.

ROF yakhala ikuyang'ana kwambiri mabwalo ophatikizika a electro-optic ndi zigawo zake kwazaka khumi. Timapanga ma modulator ophatikizika owoneka bwino kwambiri ndipo timapereka mayankho ndi ntchito zaukadaulo kwa ofufuza asayansi ndi mainjiniya amakampani. Ma modulators a Rofea okhala ndi voteji yotsika komanso kutayika kocheperako adagwiritsidwa ntchito makamaka pakugawa makiyi a quantum, ma radio-over-fiber systems, laser sensing system, ndi ma telecommunication optical telecommunication.

Timaperekanso ma modulators ambiri osinthira makonda, monga 1 * 4 array phase modulators, Ultra-low Vpi, ndi ma Ultra-high extinction ratio modulators, omwe amagwiritsidwa ntchito m'mayunivesite ndi m'masukulu. Kuphatikiza apo, timapanganso RF amplifier (modulator driver) ndi BIAS controller, photonics detector etc.

M'tsogolomu, tidzapitiriza kukonza mndandanda wazinthu zomwe zilipo, kuti tipange gulu laukadaulo laukadaulo, pitilizani kupatsa ogwiritsa ntchito zinthu zapamwamba, zodalirika, zapamwamba komanso ntchito zaukadaulo.
