We have measured infrared (2.5~25 mum) transmission by the transverse electric (TE) mode through Au gratings on silicon substrate with various Au widths. Simulation is used by surface impedance boundary condition (SIBC) method. Simulation results agree well with experiments and offer an evanescent-wave model.

Wafer-level packaged LEDs are useful for the high power applications such as back light unit (BLU) and general solid state lighting due to the compactness and integrated fabrication process with Si-MEMS technology. In this paper, thermal characteristics of wafer-level packaged LEDs with four multi-chips are investigated including mutual thermal effects due to the adjacent chips using both serial and parallel measurement methods.

In this paper, we propose a simple fiber-optic sensing system to measure the concentration of the methane based on a special catalyst and fiber Bragg gratings (FBGs). The temperature around the catalyst rises rapidly as the concentration of methane increases, and hence can be detected by an FBG-type sensor through monitoring the wavelength shift of the reflection spectrum. By employing a well-matched FBG as a reference, the wavelength shift of the sensing FBG can be transformed effectively into the variation in the measured optical intensity. An experiment is demonstrated to show the good performances of our system, such as the high resolution and good stability to the environmental temperature.
