摘要:

为提高聚合物光波导放大器的增益性能, 利用高温法合成了BaLuF5 颐Yb3+ ,Er3+纳米晶, 并分别对纳米晶的形貌、晶体结构和近红外发射特性进行了表征。测试结果表明, 纳米晶平均粒径为13 nm, 并在1 530 nm 处具有较强的发射, 荧光半高宽为50 nm。将合成的纳米晶掺杂入SU-8 聚合物作为光波导放大器的芯层材料, 使
用光刻显影等工艺, 在表面长有二氧化硅的硅衬底上制备出了聚合物光波导放大器。当980 nm 波长泵浦光功率为280 mW、信号光波长为1 530 nm 且功率为0. 1 mW 时, 在长度为1. 1 cm 的光波导放大器中, 获得了3. 95 dB的相对增益。

Abstract:

BaLuF5 :Yb3+, Er3+ nanocrystals are synthesized with the method of high-temperature thermal decomposition. The average particle diameter of nanocrystals is 13 nm. The nanocrystals exhibit strong emission at 1530 nm. The fluorescence emission spectrum showed that the FWHM(Full Width at Half Maximum) is about 50 nm. The synthesized nanocrystals were doped into the SU-8 polymer as the core material of the optical waveguide amplifiers. The waveguide amplifier based on SU-8 doped by BaLuF5 -Yb3+,Er3+ nanocrystals was fabricated with the SiO2 upper cladding using photolithography and development process. For an 1 530 nm wavelength input signal power of 0. 1 mW and a 980 nm wavelength pump power of 280 mW, a relative optical
gain of 3. 95 dB for waveguide length of 1. 1 cm was achieved.

Key words: waveguide amplifiers, BaLuF5 :Yb3+, Er3+nanocrystals, polymer, relative gain
