Rudzi rwakajairika rweamplifier yemazisoinoshandiswa mukukurukurirana kwemaziso
Kana zviratidzo zvemaziso zvichitumirwa mufibers dzemaziso, sezvo daro richikwira, zviratidzo zvemaziso zvinopera simba zvishoma nezvishoma uye zvinotokonzera kukanganisa kutaurirana… Kusvika pakuonekwa kwema amplifiers emaziso, anenge akaita se "nzvimbo yepeturu", achizadza simba rezviratidzo zvemaziso kuitira kuti akwanise kutakura data zvakanaka kuenda kwaanoenda. Nyaya iyi ichakupa amplifier yemaziso yakajairika mukutaurirana kwemaziso - iyoamplifier yefayibha ine erbium-doped(EDFA optical amplifier).
Chishandiso che erbium-doped fiber amplifier, sezvinotaurwa nezita racho: Erbium (Er), chinhu chisingawanzoitiki chepasi, chinosanganiswa mu quartz fiber. Kana chiratidzo che input optical chikapfuura ne erbium-doped fiber, ma trivalent erbium ions (Er³⁺) anotora simba rechiedza chepombi uye anochinja kuenda kusimba rakakwirira. Huwandu hwezvikamu zviri mu excited state hunoshanduka. Pasi pe induction ye input signal light, ma excited-state rare earth ions anobuda nekusundwa uye anoburitsa ma photons ane frequency yakafanana ne signal light, nokudaro zvichiita kuti optical amplification ibudirire.
Zvinhu zvinoumbaEDFA optical amplifierKazhinji zvinosanganisira ma optical couplers (anowanzo shandisa wavelength division multiplexers WDM), ma optical isolators, ma erbium-doped fibers, ma filters, uye ma pombi sources. Pakati pawo, optical coupler inobatanidza neunyanzvi chiedza chekupinda nechiedza chepombi kuti ive nechokwadi chekuti chiratidzo chapinzwa nemazvo mu erbium-doped fiber; basa re optical isolator nderekudzivisa chiedza chisina basa chiri munzira ye optical kudzivirira masaini ekuvhiringidza asina kufanira kuti asaumbwe, zvichiita kuti chiratidzo chienderane nedivi rimwe chete; optical filter inobvisa ruzha rusingadiwe kuti ivandudze signal-to-noise ratio uye ive nechokwadi chekuti ruzivo rwunotumirwa zvakajeka.
Parizvino, vaongorori vari kugadzira ma-amplifiers e-fiber ane mabhendi maviri (DBFA) uye ma-amplifiers e-ultra-wideband (UWOA), nechinangwa chekuwedzera bandwidth ye-gain kusvika ku-wavelength division multiplexing (WDM) frequency band. Munguva pfupi yapfuura, timu yekutsvagisa yakabatana kubva kuEuropean research institutes yakagadzira traveling wave parametric amplifier yakavakirwa pama-photonic chips. Kuburikidza nechimiro chakamanikana, inowana ultra-wideband signal amplification, ine bandwidth ye140 nm (katatu kupfuura yeEDFA yechinyakare), uye vhoriyamu yaderedzwa kusvika padanho remasendimita, ichipa rutsigiro rwekumhanya kwakanyanya kune data centers uye AI computing. Aya "ma-amplifiers makuru" achatsigira kutapurirana kwema wavelengths anopfuura zana pafiber, zvichiisa hwaro hwekutaurirana kweholographic uye mafekitori akangwara nezvimwe zvinoshandiswa munguva ye6G.
