A compact integrating module technique for packaging optical multi- stage cantor network with polarization multiplex technique has been suggested in this paper.The modules have a unique configuration, which is the solid-state combination of a polarization rotator and a 2 × 2 switch array. The design and fabrication of an optical 8-channel nonblocking cantor network is demonstrated. Furthermore a fast setup control algorithm is developed. The network systems are easy to assemble and insebsitive to environment disturbance..

[in Chinese], [in Chinese], and [in Chinese]

We observed that Talbot pattern in Gaussian beam passing through aholographic grating may carry information of the beam pot size. A scheme for measuring Gaussian beam diameter based on Talbot effect is presented in this paper. By knowing the space of frings of Talbot pattern, the beam spot size projecting on the holographic grating can be obtained. This characteristic reduces the requirements to location of grating or light source and the stability of electrical circuits and light source. In this paper we describe the phenomena as a convergent Gaussian beam passing through holographic grating, and analyze the possbility of the application of Talbot effect to measuring beam diameter. Theoretical analysis, computer simulation and experiments results agree well with each other..

With pump-probe method, the photocycle of bacteriorhodopsin is studied in two sets of measuring systems which have different time resolution and exciting mode.One is carried out by a single shot pulse Xenon lamp inducing the purple membrane suspension sample. The other is performed by a repetitive Q -switch double frequency Nd : YAG laser periodically exciting the sample. The testing beam for the two systems is a 633 nm He-Ne laser. An avalanche photodiode is used to detect the probing light passing through the sample when pumped by the actinic light. The picked up signal is coupled into a 500 MHz digitizing oscilloscope which measures and processes the BR's photocycle response signal. The experimental results indicate that the period of BR photocycle is less than 15 ms, the time constant from K to L is 2 μS, the relaxation time from L to M is 50 μs. A doubtable component is found occurring prior to K. Based on the emasured data, a model of the bacteriohodopsin photocycle in the time domain from nanoseeond to millisecond is proposed..

The electron-hole competition in doped KNSBN crystal is analyzed for the first time by measuring the recording and erasing kinetics of doped KNSBN crystals. It is shown that the shorter the response time, the sharper is the competition between electrons and holes in doped KNSBN crystals. So it leads to the net index modulation and the diffraction efficiency smaller. The reason of the hole carriers increasing has been analysed in reduced Co: KNSBN crystals. The effective carrier densities are estimated as the order of 10 15 cm-3..

Substituent effect on the thirdpe order optical nonlinear properties and their excited state relaxation processes in porphyrins have been studied. In the samereplacement on phenyl of tetraphenylporphyin, we discovered that the X(3) value of H2TPP increased with donating electron group and decreased with withdrawing electron group relative to that of free base H2TPP. As the same substituent at different bearing on phenyl of tatraphenylporphyring, the X(3) value of H2TPP with donating electron group at ortho place is less than that at para place. Moreover, we found that the relaxation time of H2TPP with donating electron group is about 7 times faster than that with withdrawing electron group..

Accurate Expression of Light Intensity at Transverse Plane

By taking the vectorial property of the time-average enregy flow density into account, a new extensive definition of the light intensity is proposed.

By taking the vectorial property of the time-average enregy flow density into account, a new extensive definition of the light intensity is proposed. It is expressed as the time average of the amount of energy which crosses in a unit time and a unit area, so it can be applied to any point at any curved surface. This definition is directly related to the measurement quantity of the light intensity on a curved surface. The intensity formula shows that the light intensity at any point of a curved surface is not only related to the amplitude at the point, but also related to the included angle between the Poynting vector (time average) and the direction of the local differential surface element. Especially, as an important consequence, the light intensity on the transverse plane perpendicular to the propagation axis is given. These results can be used to study the second intensity moments and the M2 factor of the non-paraxial beams..

The steady- state distribution function of the laser intensity and phase is derived through a Fokker-Planck equation.

Compared with the laser model of independent noise terms, the coupling of quantum noise terms changes the fluctuations of either intensity or phase drastically, it also introduces coupling fluctuation between the laser intensity and phase..
