Kudzora kwe electro-optic kuburikidza ne polarization kunoitika kuburikidza ne femtosecond laser writing uye liquid crystal modulation.

Polarization electro-opticKudzora kunoitwa nekunyora kwefemtosecond laser uye modulation ye liquid crystal

Vaongorori vekuGermany vakagadzira nzira itsva yekudzora masaini emaziso nekubatanidza femtosecond laser writing ne liquid crystal.kushandurwa kwemagetsi-opticNekuisa jira rekristaro remvura mugwara remafungu, kudzora kwemagetsi kwemamiriro ekupisa kwemwaranzi kunoitika. Tekinoroji iyi inovhura mikana mitsva yemidziyo ine chip uye macircuits akaomarara ephotonic akagadzirwa uchishandisa tekinoroji yekunyora yefemtosecond laser. Chikwata chekutsvagisa chakatsanangura kuti vakagadzira sei mawave plates anogadziriswa mumawaveguides esilicon akabatanidzwa. Kana voltage ikaiswa pakristaro remvura, mamorekuru ekristaro emvura anotenderera, izvo zvinoshandura mamiriro ekupisa kwechiedza chinotumirwa mugwara remafungu. Mukuyedza kwakaitwa, vaongorori vakabudirira kugadzirisa zvachose polarization yechiedza pama wavelengths maviri akasiyana anoonekwa (Mufananidzo 1).

Kubatanidza matekinoroji maviri akakosha kuti pave nekufambira mberi kutsva mumidziyo yakabatanidzwa ye3D photonic
Kugona kwemafemtosecond lasers kunyora mawaveguides nemazvo mukati mechinhu, kwete pamusoro chete, kunoita kuti ave tekinoroji inovimbisa kuwedzera huwandu hwemawaveguides pachip imwe chete. Iyi tekinoroji inoshanda nekutarisa danda relaser rakasimba mukati mechinhu chinoonekera. Kana simba rechiedza rasvika padanho rakati, danda rinochinja hunhu hwechinhu chacho panzvimbo yaro yekushandisa, kungofanana nepeni ine micron accuracy.
Chikwata chekutsvagisa chakabatanidza matekiniki maviri ekutanga e photon kuti chiise jira remakristaro emvura mu waveguide. Sezvo danda richifamba nepakati pe waveguide uye nepakati pe liquid crystal, phase uye polarization yedanda inochinja kana simba remagetsi rashandiswa. Zvadaro, danda rakagadziriswa richaramba richipararira kuburikidza nechikamu chechipiri che waveguide, nokudaro richizadzisa kutapurirana kwechiratidzo che optical nehunhu hwe modulation. Iyi tekinoroji ye hybrid inosanganisa matekiniki maviri inogonesa mabhenefiti ezvose zviri mumudziyo mumwe chete: kune rumwe rutivi, kuwanda kwechiedza kunounzwa ne waveguide effect, uye kune rumwe rutivi, kugadziriswa kwakanyanya kwe liquid crystal. Tsvagiridzo iyi inovhura nzira itsva dzekushandisa hunhu hwe liquid crystals kuisa waveguides muhuwandu hwese hwezvishandiso semamodulatoryezvishandiso zvemifananidzo.

Mufananidzo 1 Vaongorori vakaisa zvidimbu zvemakristaro emvura mumawaveguides akagadzirwa nekunyora zvakananga nelaser, uye mudziyo wakasanganiswa unogona kushandiswa kushandura polarization yechiedza chinopfuura nemawaveguides.

Mashandisirwo uye mabhenefiti e liquid crystal mu femtosecond laser waveguide modulation
Kunyangwe zvakadaromodulation yemazisoMuma "femtosecond laser writing waveguides" akambowanikwa kare nekushandisa kupisa kwemuno kuma "waveguides", muchidzidzo ichi, "polarization" yaidzorwa zvakananga nekushandisa "liquid crystals". "Maitiro edu ane zvakanakira zvakawanda: kushandiswa kwesimba kwakaderera, kugona kugadzirisa ma "waveguides" ega ega, uye kuderedza kupindirana pakati pe "waveguides" dziri pedyo," vaongorori vanodaro. Kuti vaedze kushanda kwemuchina uyu, timu yakaisa laser mu "waveguides" uye yakachinja chiedza nekuchinja voltage inoshandiswa kune "liquid crystal layer". Shanduko dze "polarization" dzakaonekwa pakubuda dzinoenderana netariro dzedzidziso. Vaongorori vakawanawo kuti mushure mekunge "liquid crystal" yabatanidzwa ne "waveguides", hunhu hwe "modulation" hwe "liquid crystal" hwakaramba husina kuchinja. Vaongorori vanosimbisa kuti chidzidzo ichi chinongova humbowo hwepfungwa, saka kuchine basa rakawanda rinofanira kuitwa tekinoroji isati yashandiswa mukuita. Semuenzaniso, zvishandiso zviripo zvino zvinogadzirisa ma "waveguides" ese nenzira imwechete, saka timu iri kushanda kuti iwane kutonga kwakazvimirira kwe "waveguides" yega yega.
