Optical Isolator Magnet

Optical Isolator Magnets

Optical isolator yog ib qho khoom siv kho qhov muag uas tso cai rau lub teeb xa mus rau hauv ib qho kev taw qhia nkaus xwb. Optical isolator tuaj yeem siv los ua kom tsis txhob cuam tshuam lub teeb pom kev rau hauv cov khoom siv kho qhov muag, thiab nws tau siv dav hauv kev sib txuas lus kho qhov muag thiab thaj chaw laser. Optical isolator mas siv Faraday Effect ntawm magneto-optic siv lead ua. Raws li ib feem tseem ceeb ntawm optical isolator, ob qho tib si sintered Samarium Cobalt hlau nplaum thiab sintered Neodymium hlau nplaum tuaj yeem ua haujlwm raws li cov hlau nplaum optical isolator.

Magneto-optical Effect yog dab tsi?

Magneto-optical effect yog hais txog kev sib nqus teb rau kev sib cuam tshuam ntawm cov teeb meem thiab lub teeb. Lub electromagnetic nthwv dej yuav tsim ntau qhov tshwm sim thaum kis los ntawm qhov nruab nrab uas tau hloov pauv los ntawm lub xub ntiag ntawm quasi static magnetic teb. Cov pa magneto-optical nyhuv muaj xws li:

1.Faraday Effect: tuaj yeem siv rau kho qhov muag cais tawm thiab kho qhov muag circulator.

2.Kerr Effect: tuaj yeem siv rau lub koob yees duab kaw.

3.Zeeman nyhuv: tuaj yeem siv rau kev ntsuas ntawm qhov tshwj xeeb tus nqi-rau-mass piv thiab sib nqus teb ntawm lub cev xilethi-aus.

Faraday Effect yog dab tsi?

Faraday Effect yog hais txog kev sib cuam tshuam ntawm qhov chaw sib nqus thiab qhov muag yoj hauv nruab nrab. Lub polarization ntawm lub teeb polarized yuav raug hloov los ntawm qhov kev txiav txim ntawm lub magnetic teb. Faraday Effect tau siv dav hauv ntau lub ntsuas ntsuas, suav nrog kev hloov kho qhov muag, kev hloov pauv hloov pauv, thiab kev paub txog thaj tsam ntawm thaj chaw sib nqus.

Lub hauv paus ntsiab lus ntawm kev khiav hauj lwm ntawm optical isolator puag ntawm nonreciprocity ntawm Faraday rotation. Lub ntsiab tivthaiv ntawm optical isolator yog lub thiaj li hu ua Faraday rotator. Faraday rotator muaj Terbium Gallium Garnet (TGG) magneto-optical siv lead ua thiab kev ua haujlwm siab ruaj khov hlau nplaum. Lub magneto-optical siv lead ua yuav tsum tau siv lub magnetic teb haum uas yuav tsum tau cov hlau nplaum ruaj khov muab cov hlau nplaum txaus nyob rau hauv qhov chaw ntawm magneto-optical crystal. Micro Samarium Cobalt Magnets yog qhov kev xaiv tseem ceeb hauv daim ntawv thov no.
