Based on the modified coupled-wave theory
the emission characteristics
including threshold gain
photon density distribution in the cavity
and external differential quantum efficiency for second-order DFB lasers are investigated. Numerical simulation results show that for given device structure with wavelength of 1.55 m
the feedback coupling coefficient and the surface radiation coupling coefficient of the second-order grating have great influence on the emission characteristics of the device. By choosing different duty cycles of the grating
we can change the two coupling coefficients
which affect the emission characteristics. For an overall consideration
an optimal duty cycle of 0.43 is chosen. The optimized results show that the device works without degeneracy modes and spatial burning hole. Besides
the side-mode suppress ratio (SMSR) and external differential quantum efficiency reach as high as 42 dB and 47%
respectively. 2010 SPIE.

In order to solve the conductive ring module's interference problems
measured the electromagnetic radiation of Power drive module
and used test results analysis the electromagnetic compatibility of the conductive ring
identified and implemented appropriate EMC (electromagnetic compatibility) measures. When optical tracking system working
test equipment can not be fixed. Therefore
from the electromagnetic radiation theory
the paper analyzed the electromagnetic radiation of the power drive module. From it
determine the EMC pre-compliance test method for electromagnetic radiation of power drive module. Based on Test results
calculate the interference voltage of wire in Conductive ring
and then determine the corresponding EMC method. The results show that
when The power drive module Radiate Electromagnetic waves
wires would coupled common mode interference voltage
its frequency is 3MHz
amplitude is about 10V
it would interfered the operation of sensor. By reducing the area of ground loops
used shielded cables
final rule out the interference. 2010 IEEE.

Anti-radiation TSC695F is usually used as aerospace payload controller in tasks to ensure the aerospace payload having extremely high reliability in abominable space environment. The processor bases on SP ARC V7 architecture with parity check and EDAC
so it could design out high reliable bootstrap loader to guarantee the operation system of VxWorks and application codes loaded correctly and worked stable and high effective. First
this paper put forward the system hardware composition and boot mode which apply for aerospace payload
then it makes clear the related contents of register group initialization
stack initialization
system hardware initialization in bootstrap loader of TSC695F and give out the method to establish TRAP table. That's all through comparing different type of organize mode of program image. After that
compiling of target codes have been described and the kernel code of MakeFile had been given at the same time for reference aimed at the realization of engineering. Although this paper is based on TSC695F
but it could be extended to other embedded system based on SP ARC for bootstrap loader analysis and design
for example
the TSC697 which based on SP ARC V8 with higher performance
so this paper has extremely high engineering value. 2010 IEEE.
