Lake Washington Institute of Technology (LWTech) is a publicly-funded workforce college located in Kirkland, WA. The newest addition to the college’s programs list is a two year (AAS) degree in Lasers and Optical Technology which was recently approved. The program is designed for students who desire an entry-level job as a Photonics System Technician or a Specialist in one of the many Photonics companies located in the Seattle Area. In this paper, the authors outline briefly the new program’s key elements including the motivation behind selecting this project, the degree pathway, methods of instructions, preparation progress, and the current recruitment activities.
In this work, the regeneration process of FBGs written into both standard and bend-insensitive fiber has been studied. Several dopants present in these fibers lead to different regeneration properties which, based on previous experiments, have been tested, paying special attention to the regeneration temperature. The achieved results suggest a reduction on the regeneration temperature for FBGs written into bend-insensitive fiber that favors mechanical properties of silica.
A specific temperature and pressure optical fiber transducer is presented in this paper. By using a customized fiber reinforced plastic membrane with embedded Fiber Bragg Gratings, the fluid pressure and temperatures changes are converted in optical wavelength displacements. The membrane and the transducer custom design allows a suitable measurand discrimination. The transducer is implemented, characterized and calibrated. Its feasibility to be used on large diameter water pipes has been successfully validated by means of field trials. Many of these transducers will be optically multiplexed to monitoring these infrastructures.
