Modulator yesimba
Semuchina unoshandiswa zvakanyanya mumasisitimu akasiyana-siyana e optical, mhando dzawo uye mashandiro awo zvinogona kutsanangurwa sezvakawanda uye zvakaoma kunzwisisa. Nhasi, ndakugadzirirai mhinduro ina dze standard intensity modulator: mhinduro dze mechanical, mhinduro dze electro-optical, Acousto-optic scheme, uye liquid crystal scheme.
Mhinduro yeMichina
Modulator yesimba remagetsi ndiyo modulator yekutanga uye inonyanya kushandiswa zvakanyanya yesimba remagetsi. Nheyo yacho ndeyekushandura chiyero che s-light kuenda kune student muchiedza che polarized nekutenderedza hafu yewave plate uye kupatsanura chiedza kuburikidza ne analyzer. Kubva pakugadzirisa kwekutanga kwemaoko kusvika kune otomatiki uye yakanyatsogadzirwa nhasi, mhando dzezvigadzirwa zvayo uye kugadzirwa kwekushandisa zvakura. Fortune Technology inopa vatengi nhevedzano yekudzora magetsi kana manual uye inotsigira zvinhu zve polarization nezvimwe zvigadzirwa zvine chekuita nazvo kuti zvisangane nemashandisirwo akasiyana. Zvinodiwa pakugadzira:
mhinduro yemagetsi-optical
Modulator yemagetsi-optical intensity inogona kushandura simba kana amplitude yechiedza chakasanganiswa. Nheyo iyi yakavakirwa paPockels effect ye electro-optic crystal. Mushure mekunge polarized light beam yapfuura nepakati pe electro-optic crystal inoshandiswa ne electric field, polarization state inochinjwa uye inoparadzaniswa ne analyzer. Simba rechiedza chinoburitswa rinogona kudzorwa nekushandura simba re electric field, uye kukwira/kudonha kwe edge ye order ye ns kunogona kuwanikwa. Ichishandisa makore ayo ekubatsira mumunda wema electro-optic crystals, Fortune Technology yakatanga nhevedzano yema electro-optic intensity modulators akadai se high-speed shutters, zvichipa vatengi mhinduro dzakakura uye dzinogona kugadziriswa.
Purojekiti yeRuzha neChiedza
Modulator ye acousto-optic inogonawo kushandiswa se modulator ye intensity. Kuchinja mashandiro e diffraction kunogona kudzora simba re 0th order light ne 1st order light kuti zvibudirire kugadzirisa simba re light. Acousto-optic golden gate (optical attenuator) ine hunhu hwekumhanya kwe modulation nekukurumidza uye high damage threshold. Fortune Technology inogona kupa acousto-optic intensity modulators ine damage thresholds dzinopfuura 1GW/cm2 uye low scattering. Inogona kupa vatengi dhizaini yakanakisa yemhinduro zvichienderana nekumhanya kwe modulation, wavelength, beam diameter, extinction ratio, nezvimwe zviratidzo zvinodiwa nemutengi.
Mhinduro yeLCD
Zvishandiso zvemakristaro emvura zvinowanzo shandiswa sema "variable wave plates" kana "tunable filters". Kuwedzera zvinhu zvakati wandei zvinoparadzanisa mativi maviri e "liquid crystal cell" uko kunoiswa "driving voltage" kunogona kugadzirwa kuita "liquid crystal shutter" kana "variable attenuator". Chigadzirwa ichi chine "clear aperture"—zvinhu zvakaita sehukuru uye kuvimbika kwakanyanya.
Beijing Rofea Optoelectronics Co., Ltd. iri mu "Silicon Valley" yeChina - Beijing Zhongguancun, ikambani yetekinoroji yepamusoro yakatsaurirwa kushandira masangano ekutsvagisa emuno nekunze kwenyika, masangano ekutsvagisa, mayunivhesiti nevashandi vekutsvagisa sainzi vemabhizinesi. Kambani yedu inonyanya kuita tsvakurudzo yakazvimirira nekugadzira, dhizaini, kugadzira, kutengesa zvigadzirwa zve optoelectronic, uye inopa mhinduro itsva uye masevhisi ehunyanzvi, akagadzirirwa vaongorori vesainzi nemainjiniya emaindasitiri. Mushure memakore ekuvandudza kwakazvimirira, yakagadzira nhevedzano yakapfuma uye yakakwana yezvigadzirwa zve photoelectric, izvo zvinoshandiswa zvakanyanya mumaindasitiri emaguta, emauto, ekufambisa, emagetsi, emari, dzidzo, ekurapa nedzimwe nzvimbo.
