The final R and wR are 0.0349 and 0 0894 for 2008 observed reflections (I≥2σ(I )), respectively. In the molecule of the title compound , there is an intramolecular hydrogen bond between the amide N and benzyl O atoms , forming a six membered ring in the central part of molecule. In the crystal, molecules are connected into infinite zigzag chains by N-H…S (- x, -y+1, -z ) and weak interaction N-H…O ( -x+1,-y+1,-z+1 ) along the direction 〔101〕(a+c). The weak intermolecular interaction Cl…Cl (- x, -y, -z ) links the chains into a layer. Between the resulting layers there are mainly van der Waals interactions.

A 1×8 GaAs/GaAlAs optical power splitter based on a MultiMode Interference (MMI) coupler is presented. The input and output single mode waveguides are optimized by the Discrete Spectral Index Method (DSIM) and a moderate square spot on the output in deep etched rib waveguides is obtained. The fabrication tolerance has been analyzed by the Finite Difference Beam Propagation Method (FDBPM). The device was fabricated by the dry etching technique and the near field output obtained. The device shows polarization insensitive, large fabrication tolerance, low theoretical excess loss and low power imbalance.

Using transmission function and diffraction loss function, the crosstalk, diffraction loss and non\|uniformity of the 1×8 arrayed\|waveguide grating multi/demultiplexer are simulated and values of 2M+1 and width of the tapered waveguide are optimized. The simulation results verify that the device we’ve designed has high performance.
