We present the design of 8-channel, 100 GHz Si3N4 based AWGs applying our proprietary AWG-Parameters tool. This tool was already used in various silica based AWG designs and also technologically verified. The designed AWGs were simulated by two commercial photonics tools and the achieved transmission characteristics were evaluated. The AWGs were designed for TM-polarized light with a central wavelength...
In this paper we investigate optical properties of 1×16 splitters based on Y-branch and MMI approaches. These splitters were designed, simulated and the obtained results of both approaches were studies and compared with each other. Additionally, we will show that the used standard waveguide core size (usually 6 × 6 µm2 to match the diameter of the single mode input/output fibers, i.e. to keep the...
We present the design and simulation of low loss 1 × 64 Y-branch optical splitter having the symmetric splitting ratio and small footprint. This was reached by optimizing the used waveguide structure that eliminates the presence of the first mode, causing the asymmetric splitting ratio of the split power over all the output waveguides. This way we were able to reduce the length of the splitter to...
The food-borne pathogens Salmonella typhimurium and Listeria monocytogenes were effectively eliminated from suspended organic waste during the thermophilic (55 o C) phase of a two-stage thermophilic/mesophilic anaerobic reactor. The feasibility of PCR technology was evaluated in order to improve the speed of detection and reduce the effort involved in detecting the presence of a range of...
