Realization of Wide Band Tunable Solid-State Dye Optical Amplification

对有机染料 4 Dieyanomethylene 2 methyl 6 (p dimethylaminostyryl) 4H pyran(DCM)掺杂的PMMA(聚甲基丙烯酸甲酯 )以及DCM掺杂的PMMA/凝胶玻璃复合材料平面光波导中的放大自发辐射进行了研究。实验表明 ,通过合理地控制波导层的折射率及厚度 ,可以在较宽范围内选择放大自发辐射的波长 ,从而实现波长调谐 ,波长调谐范围可达 30nm。该方法可应用于固体可调谐激光器及光放大器的宽带调谐。

Amplified spontaneous emission (ASE) in organic dye DCM doped PMMA and DCM doped PMMA/silica gel hybrid material planar waveguide are investigated. By controlling of the refractive index and the thickness of the waveguide, the ASE wavelength can be selected in a wide range and wavelength tuning is realized. The tuning range can reach 30 nm. The method can be applied to the wide band tuning of solid-state tunable lasers and optical amplifiers.
