	Research on the close noise field of the piezoelectric pump (EI CONFERENCE) 会议论文 OAI收割 2006 IEEE International Conference on Mechatronics and Automation, ICMA 2006, June 25, 2006 - June 28, 2006, Luoyang, China Jizhuang L.; Jianhui Z.; Shouyin W.; Qixiao X.; Desheng L. 收藏 \| 浏览/下载：54/0 \| 提交时间：2013/03/25 Restraining the noise meanwhile improving the dynamic characteristics of the driving power of piezoelectric pump effectively are the final purposes of doing research on the reciprocating and flexural vibration of the piezoelectric vibrator. However among many papers regarding piezoelectric pump there are very few papers about the research on the noise of piezoelectric pump. This is far less than the research on the application of the piezoelectric pump in other fields. In this paper the research on the flexural vibration deformation and vibration radiation noise of the piezoelectric vibrator are carried out. Firstly the vibration equations of the piezoelectric vibrator are built and flexural vibration deformation function is deduced. Then the simplified vibration model of the piezoelectric vibrator is introduced by using vibration theories of micro-area piston. Furthermore theoretical calculation equations of sound pressure in close noise field and noise contribution equation of fluid in pump are deduced. Finally a comparison is made between the theoretical calculation value and experimental value and the contribution quantities of the piezoelectric vibrator and fluid in pump are obtained respectively under different frequencies. The consequence approves that the theory introduced by this research is true. 2006 IEEE.
	Tandem electroabsorption modulators integrated with DFB laser by ultra-low-pressure selective-area-growth MOCVD for 10 GHz optical short pulse generation 期刊论文 OAI收割 semiconductor science and technology, 2005, 卷号: 20, 期号: 8, 页码: 882-885 Zhao, Q; Pan, JQ; Zhang, J; Zhou, GT; Wu, J; Wang, LF; Wang, W 收藏 \| 浏览/下载：121/47 \| 提交时间：2010/03/17 摘要: A novel device of tandem MQW EAMs monolithically integrated with a DFB laser is fabricated by an ultra-low-pressure (22 mbar) selective area growth MOCVD technique. Experimental results exhibit superior device characteristics with low threshold of 19 mA output light power of 4.5 mW and over 20 dB extinction ratio when coupled to a single mode fibre. Moreover over 10 GHz modulation bandwidth is developed with a driving voltage of 2 V. Using this sinusoidal voltage driven integrated device 10 GHz repetition rate pulse with an actual width of 13.7 ps without any compression elements is obtained.
