Fabrication of optical waveguide amplifiers based on bonding-type NaYF4∶Er nanoparticles-polymer
摘要
Abstract
In order to improve the uniformity and stability of the rare earth doped active materials, a copolymerization typed material is presented to fabricate the waveguide amplifiers.Oleic acid (OA)-NaYF4∶Er nanoparticles are synthesized by the high-temperature pyrolysis, and the active core materials are prepared by the copolymerization of the outermost oleic acid of the nanoparticles and methylmethacrylate(MMA).The concentration of nanoparticles in the active materials is about 1wt%.Atomic force microscopy image shows that the active film is very smooth, and the root mean square is about 1.76 nm.Ellipsometry is used to measure the refractive index of the material, which is about 1.485 at 1 550 nm wavelength.Embedded single-mode waveguides are designed.The distributions of electric field intensity and the transmission mode are simulated by finite element method.The waveguide amplifiers are prepared by the photolithography and inductively coupled plasma.The experimental results show that the relative gains of 3.58 dB is obtained in a 1.2 cm long device, when the pump power is 390 mW at 1 480 nm wavelength and the signal power is 0.1 mW at 1 550 nm wavelength.关键词
