passive films
解釋
鈍化膜-
We use the laser output ( 320 nm, 200 fs ) of optical parametric amplifier ( opa ) in < wp = 5 > an active passive mode - locked femtosecond ti - sapphire laser operating at a repetition rate of 1khz as a exciting resource to develop optically pumped stimulated emission of zno thin films. when rectangular stripe laser irradiates thin films, optical resonant cavity is naturally formed between two nanocrystallites along with the rectangular laser stripe and planar weveguide confines the light scattering
利用飛秒激光器作為光泵浦激發光源，研究了氧化鋅薄膜的光泵浦受激發射，當條形光斑輻照薄膜樣品時，將沿著光斑條由氧化鋅納米晶面自然地形成光學諧振腔，由於平面介質波導結構限制光散射，所以成功地觀測到二氧化硅襯底上的納米氧化鋅（ zno ）薄膜的紫外受激發射。 -
The research progress and the facing difficulties of active / passive planar optical waveguides were systematically summarized and reviewed in this paper. zro2 - si02 binary oxide gel glasses and films applied for active optical waveguides were prepared by the sol - gel method with zirconium oxychloride and tetraethoxysilane as precursors. the paper has investigated the influence of the compositions of system and heat treatment temperature on the system refractive index in zroj - sioj binary oxide gel glasses
