In this paper, a 100-Gb/s optical transceiver module is designed in accordance with 100GBASE-SR4 standard. Clock and data recovery (CDR) chips are used in the module to improve the performance of input and output signals. The printed circuit board (PCB) and optical engine of the module are also designed.

We discuss the performances of multi-chip white light LED packages with a proposed green-emitting Ce6Tb0.33MgAl11O19:Ce,Tb (CTMAOCT) phosphor. We find that an appropriate combination of yellow phosphor Y3Al5O12:Ce3+ (YAG:Ce) and green phosphor CTMAOCT can bring the significant improvement on angular color uniformity and luminous flux.

In this paper, we discuss the performance of the multi-chip white light LED packages with the proposed silicon dioxides (SiO2) structures. Through the research results, it is suggested that the hybrid SiO2 structure with its size around 1µm can be suitable for obtaining higher color uniformity.

The pressure-dependent Raman phonon behaviors of 6H-SiC bulk material were studied up to 20 GPa with a diamond anvil cell (DAC). The frequencies of LO(Γ) and TO(Γ) Raman modes and LO-TO splitting increases with increasing pressures. The mode-Grüneisen parameters for Raman modes of 6H-SiC are determined experimentally.

In this paper, we used geometrical optics and dispersion theory to calculate the relation between dispersion angle, rotation angle and vertex angle. We get the formula of dispersion angle; then we use an optical simulation software SPEOS to verify the formula. The results shows that when the vertex angle is 50° and ration angle is +15°, the maximum dispersion angle is 4.803°.

Recent year, embedded lamp has been used widely in interior lighting. But it has some problem about low light range and low illuminance uniformity. This paper uses turned reflective mirror and LED to improve the problem. We discovery that the light reflecting from turning reflective mirror can increase the wall light illumination area. Results show that the illuminance ratio can be improved by 71.65%.

In this paper, we design a 12-channel optical transceiver module at 10-Gb/s/ch and its evaluation board (EVB) based on 100GBASE-SR10 with CXP interface. The structure of the module was created through Solidworks, and the printed circuit board layouts of the module and EVB were designed through Altium Designer.
