The implementation of Cloud Computing over optical networks faces many challenges and opportunities. A cloud computing architecture over optical networks is proposed based on the service plane. And the validity of the architecture we proposed was experimentally demonstrated in our Adaptive Multi-Service Optical Network testbed.

Different technical challenges for migration from GPON to 10GPON are discussed and also put into context of standardization. The challenges include how to handle an increased upstream capacity through use of burst-mode receivers and DBA algorithms, extension of reach and wavelength planning for future proofing the fiber infrastructure. Finally the roadmap towards 10GPON standardization is discussed.

A novel scheme for tunable optical pulse generation based on fiber sagnac loop was proposed and studied. The key parameters of the optical pulse were analyzed and testified by experiments. The repetition rate of optical pulse is twice the frequency of external square wave modulation signal and can be tuned directly by varying modulation frequency. The maximal peak value can be achieved when the peak-peak value of the square wave modulation signal was equal to the half-wave voltage of the phase modulator. Experimental results agree well with theoretical predictions.

the growth of long period fiber grating written in H2-loaded fiber within one hour immediately after fabrication was measured and analyzed. Fast deepen on difference of refraction index was obviously observed in all the experiments, but the peak wavelength to time and cross-coupling coefficient to time curves are fitted better in exponential decay function than power function, and suggest a same variation pattern in difference of refraction index.

A recognition method based on the gait characteristic for walking intrusion signal is presented. The vibration signal caused by a walker is intermittent and periodical. This signal characteristic can distinguish a human intrusion from an animal and other random disturbance. The experimental results verified the effectiveness of the proposed method.

We propose an ultra compact structure for Dense Wavelength Division Multiplexing (DWDM) systems using resonance cavity in Photonic Crystal (PC) structure. To the best of our knowledge, this is for the first time that a PC-based demultiplexer has been achieved with 0.8nm channel spacing, −18.77dB and 4170 average crosstalk and quality factor, respectively without using particular materials or complexities in fabrication. Two-dimensional (2D) Finite-Difference-Time-Domain (FDTD) method is chosen for simulation in this work.

The athermal all-polymer waveguide microring resonator is realized by selecting polymer substrate with proper thermal expansion coefficient to substitute the silicon one. The designed results show that the maximal resonant wavelength shift is −0.0085nm and the maximal temperature dependent wavelength shift slope is −0.0009nm/K when the temperature varies from 20°C to 65°C.
