Planar waveguide optical splitter thiab fusion tapered optical splitter.
Planar waveguide hom optical splitter: Planar waveguide hom yog micro-optical tivthaiv hom khoom. Nws siv photolithography thev naus laus zis los tsim kho qhov muag ntuag qhov muag ntawm lub dielectric lossis semiconductor substrate kom tau cov ceg xa tawm. Kev ploj yog qhov tsis txaus ntseeg rau qhov pom kev wavelengths thiab tuaj yeem ua tau raws li qhov sib txawv ntawm cov kab hluav taws xob Hloov kev xav tau. Lub teeb yog tusyees sib cais, thiab cov teeb liab tuaj yeem xa tusyees siv ntau yam. (Planar waveguide hom yog tag nrho-band splitter 1260-1650nm).
Fusion taper optical splitter: Lub fusion taper khoom yog tsim los ntawm fusion splicing ob lossis ntau dua optical fibers nyob rau sab, uas tuaj yeem paub txog qhov kev faib tawm ntawm lub teeb. (Cov kab hluav taws xob tseem ceeb yog 850, 1310, 1490, 1550nm).
