	Abstract:In this paper, a liquid-core photonic crystal fiber (LCPCF) with small hollow-core filled by chalcogenide material CS2 is designed. The supercontinuum (SC) generation in such a LCPCF with nonlinear coefficient of 3327 W-1okm-1 at 1550 nm and wide normal dispersion regime spanning from 1200 to 2500 nm is numerically studied by solving the generalized nonlinear Schr?dinger equation. The influences of the pump pulse parameters on the SC spectral width and coherence are demonstrated, and the optimum pump condition for the SC generation is determined. Our study work can provide an alternative way for obtaining highly coherent SC, which is important for the applications in optical coherence tomography, frequency combs, and ultrashort pulse generation.

	Abstract:A method for measuring blood oxygenation and blood flow rate using a single widely tunable semiconductor laser is proposed and investigated. It is shown that a 700-nm-band tunable laser gives the highest sensitivity for blood oxygen measurement. The corresponding tunable laser is designed using the V-coupled cavity structure. The wavelength tuning range can reach 8 nm, which is sufficient for the blood oxygenation measurement in the 700-nm-band by using the Beer-Lambert law. In contrast to conventional blood oxygenation measurement method based on two LEDs, the laser can be used at the same time to measure the blood flow rate based on the Doppler principle.

	Abstract:In this article we propose a novel Raman spectroscopic sensor which employs silicon nanowire waveguides for excitation and collection of Raman signal, and an integrated micro-ring resonator as a filter. Preliminary experimental results show that the extinction ratio of the filter including the ring resonator together with the grating coupler is more than 60 dB and the total insertion loss from the laser to the detector is less than 10dB. Theoretical calculations indicate that this high stray light rejection of the filter allows the observation of Raman signal at frequency as low as 4 cm-1. By employing the evanescent field of the silicon waveguide as excitation and collection of Raman signal, along with the integration of the filter and potentially a tunable semiconductor laser and the detector, a miniaturized Raman spectroscopic sensor can be realized on SOI platform.

	Abstract:We have observed four-wave mixing (FWM) processes in a double-Λ level of rubidium atomic system with electromagnetically induced transparency (EIT) windows with different laser polarization configuration having different polarization. The Autler-Townes (AT) splitting induced by the generated field of FWM is observed and two controlled FWM processes are correlated by their intensities. Besides, sharp peak and broad peak of the correlationare are studied. We also studied the methodology to control the noise correlation with different variants of dressing fields. Meanwhile,we also found the relationship between correlation (anti-correlation) with that of intensity-difference squeezing (anti-squeezing). The associated results may be applicable in all-optical communication and optical information processing on photonic chips.

	Abstract:We report experimental observation of intensity noise correlation between six-wave mixing (SWM), fluorescence and probe transmission signals in a coherently-prepared blockaded Rydberg atomic ensemble. Chaotic behaviors, caused by the enhanced dispersion and nonlinearity from two dressing competition, are studied through noise correlation. The generation of the correlation between probe transmission and SWM, anti-correlation between probe transmission and fluorescence signal, as well as anti-correlation between SWM and fluorescence signal are studied. Dressing effect and blockade effect are used to control the intensity correlation. The investigation has potential applications in multichannel quantum computation.

	Abstract:In this paper, a novel hybrid-core photonic crystal fiber (HCPCF) with large birefringence and high nonlinearity is designed. The optical characteristics including the birefringence, nonlinear coefficient, and group-velocity dispersion (GVD) are studied by full-vector finite element method (FV-FEM). Simulation results show that the birefringence of 0.119 and nonlinear coefficient of 3.42 W-1om-1 around 1550 nm can be obtained simultaneously, and the GVD can be easily adjusted by arranging the strcture of this fiber. This HCPCF designed will be widely used in optical communication and sensor system.

	Abstract:By adopting four parallel-coupling microring resonators as basic routing elements, device architecture and design scheme of a kind of four-port optical router are proposed, which can passively route three channel wavelengths. First, structural parameters of the routing element are optimized for single-mode transmission, low optical loss and phase-match between microring waveguide and channel waveguide. Then, detailed routing topology of the router is presented, and characteristic parameters of the four-port optical router including spectrum characteristic, insertion loss, and crosstalk are calculated in detail. Under the selected three channel wavelengths, the insertion losses along all routing paths are within 0.02~0.6 dB, and the crosstalk is less than -23 dB.

	Abstract:In the past decade, plasmonic resonators have emerged and exploited field compression to create ultra-small mode-volume devices and to enhance light-matter interactions. We propose a ring resonator on metal substrate separated by low-permittivity dielectric, which supports hybrid plasmonic modes with highly localized electromagnetic ?eld. Finite difference time domain (FDTD) method is used to calculate the properties of the ring resonator. By changing the cavity's geometry and low-permittivity dielectric's height, high quality factor of 354 along with ultra-compact mode confinement 0.0078 (λ/2n)3 ~ 0.0001um3 is achieved, leading to Purcell factor up to 2.7 x 104. Moreover, the mode volume remains of the order of 0.01(λ/2n)3 with quality factor bigger than 100 for a ring radius and thickness in the range of nanometers. The hybrid plasmonic ring resonator exhibits a trade-off between the high quality factor and the ultra-small mode volume at deep subwavelength scale in the visible spectrum. It holds great potential in fundamental physics and applications in photonics and optoelectronics, for instance, cavity quantum electrodynamics in weak coupling regime and low-threshold lasers.

	9. Study on the performance of the raised-cosine structure with relative low index dielectric regions surface plasmon polaritons waveguides

	Abstract:In this paper, A novel raised-cosine structure with relative low index dielectric regions surface plasmon polaritons(SPPs) waveguide is proposed. In the waveguide, the raised-cosine structure is introduced to the waveguide's dielectric regions innovatively. Then the field distribution, the normalized mode area, the propagation length and the figures of merit are calculated at the telecom wavelength of =1550nm. The relationship between the waveguide's performance and the shape of waveguide's relative low index dielectric regions(RLIDRs) is also discussed. It is found that the proposed waveguide had the longer propagation length than the conventional rectangle RLIDRs SPPs waveguide and it also has a strong capability of the field confinement. Moreover, with the change of the roll factor of the RLIDRs, the proposed waveguide's performance doesn't change greatly, when the between 0.02 and 0.2, its performance almost has no change. That means the machining error has a negligible impact on the waveguide's performance and it will have a greater potential in the application. All the simulations in this paper were performed by using rigorous numerical schemes based on finite-element method (FEM).

	Abstract:a plasmonic whispering-gallery-mode cavity comprising of a semiconductor ring separated from a metal surface by a nanoscale dielectric gap is proposed and numerically investigated. The nanoscale ring resonator supports hybrid plasmonic modes with highly localized electromagnetic fields, featuring an ultra-small mode volume ～0.00129 μm3. The total quality factor is found to be limited by two mechanisms, the metal radiation loss and the absorption loss, and exhibits a tradeoff with the mode volume.
