A convenient 3D measurement using amateur digital camera is enormously expected in various fields with appearance of the low cost and high-resolution amateur digital cameras. In these circumstances, t...
We report fabrication of the first low-loss, broadband 37-cell photonic bandgap fiber.Exploiting absence of surface modes and low cross-talk in the fiber we demonstrate mode division multiplexing over...
This paper discusses a feature of projective geometry which causes eccentricity in the image measurement of circular and spherical targets. While it is commonly known that flat circular targets can ha...
We design an extremely compact photonic crystal waveguide spatial mode converter which converts the fundamental even mode to the higher order odd mode with nearly 100% efficiency. We adapt a pre...
A self-ordered ring (SOR) fluorescence microscopic imaging technique has been developed for the determination of trace amounts of sulfadiazine based on its derivatization with fluorescamine. In the pr...
We have developed a novel optical fiber ring laser using a semiconductor optical amplifier (SOA) as the gain medium, and taking advantage of polarization anisotropy of its gain. The frequency differen...
Fourier transform infrared spectroscopy (FTIR) and circular dichroism (CD) were used to investigate the conformational changes of heated whey protein (WP) and the corresponding changes in the hydrolys...
A computer generated quadratic and higher order apertures are constructed and the corresponding numerical speckle images are obtained. Secondly, the numerical images of the autocorrelation intensity o...
In this paper we discussed the behavior of a hydrogen atom in moving and found there is a speed threshold for hydrogen atom. As long as the speed of hydrogen reaches or beyond its speed threshold, the...
A synthesis scheme to generate microwave triangular-shaped pulses based on spectral shaping and frequency-to-time mapping is proposed. Triangular-shaped signals with periods of 0.2ns, 0.4ns, 1.6ns and...
The high-contrast gratings assisted hollow-core waveguide demonstrates an ultra-low nonlinearity (<6×10 -13 /W/m). Digital and analog system-level simulations further show that the waveguide does not...
We show that phase to intensity modulation conversion induced by third-order dispersion doubles the modulation frequency, and therefore, the third-order dispersion does not affect group velocity dispe...
First commercial 100Gbps EO polymer modulator and its use in time-stretch A/D converter to monitor the high frequency performance of the modulator and achieving 100GHz A/D conversion is shown.
An integrated-optic demultiplexer for 8 x 10 Gbaud OFDM sub-carrier channels is realized, which comprises a PLC-based 8 x 8 optical FFT circuit. It is successfully used to demultiplex a 160 Gbit/s OFD...
The relationship between ambient relative humidity H and the position shift of a spectral line was investigated both experimentally and theoretically. An echelle-based ICP emission spectrometer equip...
