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.

Each disciplinary has its own modeling and analysis tools to solve its own specific field problems. In order to achieve integrated simulation of high precision space optical systems and predict optical performance respective to the mechanical and thermal loads
data must pass through different analysis tools. Simulation tools used in the thermal
structural and optical design process and the relationship among them were first depicted and the integrated simulation methods were described in detail. Zernike polynomial fitting methods and interpolating approaches were also demonstrated. Because of the orthogonality of Zernike polynomials
it was not probably used in some situations such as noncircular apertures and discrete data
and the coupling of Zernike polynomial coefficients and other methods were also introduced in the paper. The toolkit OMTIA (Optical
Mechanical and Thermal Integrated Analyzer) based on the methods was developed
which appears as an indispensable tool for engineering practice.

This paper proposes a design of polymer Triple Ring Resonators Filter (TRRF) based on silicon substrate. The device structure was demonstrated in order to get wide Free Spectral Ranger (FSR) of the device and a box-like filter response. The transmission equation of the amplitude of input and output lightwaves and coupling coefficients were analyzed by coupling mode theory also.
