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.

The characters of zero anti-symmetric (A0) and zero symmetric modes (S0) of Lamb wave sensor loaded with liquid were investigated and compared in the paper. It was found that due to the their different acoustic penetration depths inside the liquid the changes of the surface characteristics of the sensor and the characteristics of liquid near the surface can be identified respectively by combined A0 and S0 modes simultaneously. At the same time
the mass sensitivities of both A0 mode and S0 mode of a 2m Lamb wave sensor were demonstrated experimentally. It was proved that S0 mode has higher sensitivity to surface mass changes and the mass sensitivity of the acoustic sensor can be improved further.
