We demonstrate a signal wavelength independent SBS slow light architecture using a XGM-wavelength converter and a Brillouin fiber laser. The signal is wavelength converted to become automatically aligned with the resonance induced by SBS.
We report the observation of coherent phonon oscillations of RBMS excited by the E11 transition in isolated SWNTs. We observe stronger intensity for the (n-m)mod3 = +1 family than for the (n-m)mod3 = −1 family.
We demonstrate an optical signal monitoring method for NRZ-DPSK signals using asynchronous delay tap sampling and Hausdorff distance measure. The application of the technique for residual dispersion monitoring is demonstrated and high tolerance to other impairments and pulse shape is shown.
We demonstrate scale-dependent near-field photoluminescence of InAs quantum dots. Our analysis, based on eigen-decomposition, leads to a novel non-pixelated memory architecture thanks to spectral diversity obtained at an optimal scale of optical near-fields.
The purpose of this study is to explore the feasibility of combining near-infrared (NIR) autofluorescence and Raman spectroscopy to enhance the in vivo detection of cervical intraepithelial neoplasia.
We propose a biosensor based on the diffraction of Bloch surface waves (BSWs) in periodic dielectric stacks. Great enhancement of diffraction efficiency by a grating of proteins is predicted when BSW is excited.
Zero- n bandgap has been observed in photonic superlattices consisting of layered stack of materials with positive index of refraction and photonic crystal slab. An experimental verification of FDTD simulations is reported here.
We provide the first demonstration of linear Shockley-like surface states in optically-induced semi-infinite photonic lattices with alternating strong/weak couplings. Such surface states appear in superlattices only when the surface termination is specially designed.
We introduce a simple procedure for high-Q cavity design in photonic crystal heterostructures. The key parameter in the optimization process is the relative position of the resonant frequency within the mode-gap.
We analyze beam displacements that occur upon reflection at interfaces between homogeneous media and metamaterials. Emphasis is put on system requirements, the techniques to predict the shift and the peculiarities in the presence of metamaterials.
A large-stroke bimorph was used to reduce the time-to-full brightness of a Nd:YLF laser by a factor of 3. The 31-element mirror has the potential to combine this transient control with steady state brightness optimisation.
A 90fs pulse is focused in air, to non-ionizing intensity. A collinear probe pulse follows the pump into a region of spontaneously re-aligned N2. The aligned molecules can affect the focusing and filamenting of the probe.
We propose a new class of all-optical self-adaptive optomechanical circuits, enabling the manipulation of cavity resonances through resonantly tailored optomechanical potentials, leading to control of cantilevers with picometer precision and self-aligning microcavities.
We discuss a passively modelocked VECSEL with both gain and saturable absorber integrated into a single semiconductor structure. We refer to this new kind of laser as the modelocked integrated external-cavity surface emitting laser (MIXSEL).
We demonstrate a bowtie geometry in a silicon planar resonator with an ultra-small modal volume .01(λ/2n)3. Bowtie, ring resonators and 1D and 2D photonic crystal resonators are compared for tradeoffs in confinement and quality factors.
We report the first room temperature CW operation of two dimensional single-mode edge-emitting photonic crystal Bragg lasers. Single-mode lasing with single-lobed, diffraction limited far-fields is obtained for 100μm wide and 550μm long on-chip devices.
Splitting of mode wavelength and loss are observed in coupled photonic-crystal cavities. The characteristics of loss splitting are shown to have important impact on the optical energy transfer between such coupled resonators.
We demonstrate a pair of strongly-coupled, stacked monolithic silicon nitride microdisk resonators coupled to a tapered optical fiber. High-frequency optomechanical interactions between the two microdisks are induced by both optical force and photothermal effects.
