Conventional bead-based micro immunoassays do not guarantee high reliability because of the working principle for the trapping methods which cause inconsistency in trapping of cytometric beads. This paper presents a new bead-based micro immunoassay system for multiple or semicontinuous assays with high reliability and accuracy using hole-patterned structures and double-cladding optical fibers. Trapping test showed selective trapping of beads and consistency of the number of the trapped beads over repeated tests. Immunoassay using IL-6 showed that the cytometric beads were trapped in ordered fashion and provided a detection limit on the order of pg/ml.

In this paper, we propose a colored multigraph model for the temporarily available wavelengths. Based on this colored multigraph model, a polynomial time algorithm with complexity O(N2) is also proposed to develop an integrated dynamic routing and wavelength assignment, where N is the number of nodes in a WDM network.

We numerically investigate a new function modified from Hamming function to apply in weighting the waveguide structure of a mismatched optical coupler with the characteristics of low crosstalk, short length, and broad C+L-band. The full factorial design and beam propagation method are being used to seek the optimal structure parameters of coupling waveguide. This modified Hamming weighting function (M-HWF) is proved to have the superior performances to Hamming weighting function (HWF) in several ways. In theoretical computation, the M-HWF and HWF waveguides have the coupling lengths of 11 mm and 16 mm, respectively at crosstalk of −40 dB and operating wavelength of 1.57 µm. After the numerical design of waveguide structure parameters, the M-HWF also obtain a shorter coupling length of 4.50 mm than coupling length of 5.90 mm of HWF at crosstalk of −40 dB and within the C+L-band (1.53∼1.61 µm). The M-HWF waveguide with the shortest coupling length of 4.5 mm can even reach a broader bandwidth between 1.50 and 1.70 µm.

A spectrometer is used to measure numerical aperture (NA) of photonic crystal fibers (PCFs), and the high-precision result is obtained. We get the NA at any wavelength in 500∼900nm range, which is determined by light source and spectrometer. The measured results and theoretical calculation value match very well.

We report a radially polarized coherent anti-Stokes Raman scattering (CARS) microscopy to facilitate longitudinally oriented molecules detection. We demonstrate that combining both the radially and linearly polarized excitation schemes, CARS microscopy can be a very powerful tool for identifying the 3-D orientations of molecules with high sensitivity and chemical specificity.

To cope with the development of Carrier-suppressed-return-to-zero-on-off-keying (CSRZ-OOK) modulation format, it is of great significance to investigate all-optical logic gates to process CSRZ-OOK format signals. To the best of our knowledge, for CSRZ-OOK signals, only logic AND gate has been demonstrated while other logic functions haven't been explored until now. In this paper, an all-optical logic unit to process CSRZ-OOK signals based on four-wave mixing (FWM) arising in a semiconductor optical amplifier (SOA) is proposed. A logic OR gate and two logic AND gates with the CSRZ-OOK format unchanged could be simultaneously achieved without reconfiguration in this single unit. The performance of 40 Gb/s logic operation is firstly evaluated with numerical simulations by a comprehensive dynamic model considering three-input induced FWM in an SOA. Then, experimental demonstrations at 10 Gb/s with clear waveforms and high extinction ratios (ERs) further verify the logic integrity of this scheme.

We propose a Mixed Sharing Auxiliary Graph (MSAG) for dynamic traffic grooming in heterogeneous WDM mesh networks. Based on MSAG model, a novel heuristic named BLSW-ILMS (Backup LSP Shared Working Lightpath with Inter-layer Mixed Sharing) is proposed. Simulation results show that the proposed algorithm can efficiently decrease the blocking probability.
