The Design of a Fiber-Coupling Micro-Lens Array for an M × N Wavelength-Selective Switch.

The M × N port wavelength-selective switch (WSS) is a crucial device used for Reconfigurable Optical Add/Drop Multiplexors and optical switching nodes in optical communication systems. The primary function of an M × N port WSS is to simultaneously transmit and switch multiple input optical signals from input fiber ports to output fiber ports through spatial light coupling. The port array module in a WSS that is responsible for coupling the spatial beam with the fiber determines the important parameters of the M × N port WSS, such as the number of input/output ports and insertion loss.

Redescription of Yin, Peng, Yan & Kim, 2004 (Araneae, Thomisidae), with the first description of the male.

The male of Yin, Peng, Yan & Kim, 2004 is described for the first time from Jinggang Mountain, Ji'an City, Jiangxi Province, China. Based on male and female specimens, the species is redescribed, comprehensively illustrated, and its geographic distribution in China is delimited and discussed.

Five new Lathys species (Araneae: Dictynidae) from South China and the first description of the male of Lathys spiralis Zhang, Hu Zhang, 2012.

Dictynidae spiders were collected from Jinggang Mountain National Nature Reserve, Jiangxi Province, China in the past four years. Five new species are described and illustrated with photographs, SEMs and line drawings: Lathys adunca Liu spec. nov.
