Design of 160-Channel Si3N4 based AWG-Spectrometer for Medical Applications

, , , , , , , , , , ,
We present the design of 160-channel, 50-GHz Si3N4 based AWG applying our proprietary AWG-Parameters tool. For the simulations of the AWG layout, we used PHASAR photonics tool from Optiwave. The simulated transmission characteristics were then [...]

Effects of Heat Treatment of ZnS Nanoparticles Prepared by Hydrothermal Synthesis on Microstructure and Optical Properties in Spark Plasma Sintering (SPS)

, , , , , , , ,
Zinc sulfide (ZnS) is one of the most widely used infrared transmitting window and lens materials for systems operating in the long wave range (8~12 ㎛). ZnS nanoparticles have been intensively studied because of their [...]
