8 All Polarization Maintaining Erbium-doped and Mode-locked Figure-Eight Fiber Lasers with Different Configurations(No.073A50198) We demonstrate several ways of achievement of mode-locking in a figure-eight (F8) fiber laser which is comprised of an all polarization-maintaining (PM) fiber structure utilizing a nonlinear amplifying loop mirror to get passive mode-locking. In order to achieve stable mode-locking with low phase noise, different elements and configurations were tested and the influence of cavity   dispersion and nonlinearity to the performance of laser were elucidated. For each configuration, output characteristics including output power, optical spectrum, and autocorrelation trace were measured and compared with precedent results. We observed a particular switching behavior and the single and bound solitonic characteristics. In addition, the mode-locking of non-PM fiber laser based on nonlinear polarization rotation (NPR) has been examined to compare with that of F8 laser based on nonlinear amplifying loop mirror. Finally, a stable mode-locked figure-eight laser with nonreciprocal elements is realized, which is immune to environmental fluctuations and delivers subpicosecond pulses separated by 20 ns with timing jitter of about several picosecond integrated from 1 kHz to 1 MHz. This high stability and environment-free performance of our laser is suitable to be further developed as a source of fiber optical frequency combs.

27 Study of X-Ray Reflectivity for Multilayer Thin Films Using IMD Simulation(No.073A50105) X-ray metrology draws a lot of attention in semiconductor manufacturing due to the non-destructive properties. X-ray methods include high-resolution diffraction, topography, interferometry, and etc.. Among these technologies, specular X-ray   reflectivity (XRR) is one of the most important methods. XRR is able to measure the ultra-thin thickness down to nanometer scale and is not sensitive to structure parameters, such as single crystalline, poly-crystalline, and   amorphous. With scaling down the semiconductor device, the process control ability is more and more critical, especially thin film thickness. XRR is a promising tool to measure and monitor thin film thickness. Therefore, a software to simulate and fit XRR is necessary to achieve measuring film thickness. And IMD can reach the two purposes. In the viewpoint of film stacks, there are multi-layer structures in semiconductor manufacturing. And the XRR is able to measure multi-layer thin-film stacks. Thus, to satisfy the multi-layer thin-film stack   requirements, the XRR of the four structures,   SiO2/Si、HfO2/SiO2/Si、TiN/HfO2/SiO2/Si、TaN/TiN/HfO2/SiO2/Si, were investigated and the thin-film thickness effects were also studied. On the other hand, fitting the XRR data is necessary for further applications in semiconductor manufacturing. The XRR data generated by IMD from the previous section was fed back to IMD to implement the fitting procedure for the sake of studying the initial condition effects on the fitting results. Consequently, the article studied the feasibility of IMD in simulating and fitting XRR to enhance the feasibility of XRR in the future advanced applications.
