    Notes: Energy modulation of nonrelativistic electrons with a laser beam using a metal microslit as an interaction circuit has been investigated. An optical near field is induced in the proximity of the microslit by illumination of the laser beam. The electrons passing close to the slit are accelerated or decelerated by an evanescent wave contained in the near field whose phase velocity is equal to the velocity of the electrons. The electron–evanescent wave interaction in the microslit has been analyzed theoretically and experimentally. The theory has predicted that electron energy can be modulated at optical frequencies. Experiments performed in the infrared region have verified theoretical predictions. The electron–energy changes of more than ±5 eV with a 10 kW CO2 laser pulse at the wavelength of 10.6 μm has been successfully observed for an electron beam with an energy of less than 80 keV. © 2001 American Institute of Physics.

    Application of photoluminescence phosphors to a phosphor-liquid crystal display (2000)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 88 (2000), S. 4660-4665 
    Details
    ISSN: 1089-7550
    Source: AIP Digital Archive
    Topics: Physics
    Notes: The photoluminescence properties and quantum efficiency of potential red, green, and blue (RGB) phosphors are measured under near-ultraviolet excitation (380–420 nm). The suitability of several phosphors is discussed for their application in phosphor-liquid crystal displays (LCDs). K5Eu2.5(WO4)6.25, SrGa2S4:Eu, and BaMgAl10O17:Eu phosphors are chosen as RGB phosphors for making a phosphor-LCD prototype. The color coordinates and optical properties of phosphor-LCDs are compared to those of conventional LCDs. © 2000 American Institute of Physics.

    Detuning of the gain and reflectivity spectra and its effect on the output characteristics of vertical cavity surface emitting lasers (1995)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 66 (1995), S. 2171-2173

    ISSN: 1077-3118

    Topics: Physics
    Notes: We have investigated the effect of mismatch between the reflectivity resonance and the gain spectra of vertical cavity surface emitting lasers. Detuning was caused by hydrostatic pressure and self-heating. Hydrostatic pressure shifts the gain peak towards shorter wavelengths with respect to the Fabry-Pérot (FP) resonance without modifying the gain spectrum. The threshold current remained unchanged for a positive mismatch of up to 18 nm. It increased four-fold for a negative mismatch of −13 nm at 0.5 GPa, where lasing disappeared. Increased threshold current and quenching of the emission are a consequence of the decrease of the gain at the FP resonance. A similar effect was observed when the gain peak was red-shifted with respect to the FP resonance by increasing the injected power. Increased mismatch is accompanied by a decrease of the gain at the emission wavelength which is responsible for the laser output quenching at high injected powers. © 1995 American Institute of Physics.

    Photocurrent spectroscopy of Bragg mirrors in vertical cavity surface emitting lasers (1994)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 64 (1994), S. 400-402 
    Details
    ISSN: 1077-3118
    Source: AIP Digital Archive
    Topics: Physics
    Notes: We describe a simple technique to precisely measure the reflectivity spectra of the Bragg mirrors in individual vertical cavity surface emitting lasers. Detailed reflectivity spectra are obtained by measuring the response of the active layer junction to light impinging upon the output mirror, corrected by the active layer response spectrum. Precise measurements of the emission spectrum of the laser with respect to the Fabry–Perot notch are then possible. In the temperature range of 20–100 °C we measure the rates of 0.56 and 0.62A(ring)/°C for the mirror stack and the lasing wavelength, respectively.

    Experimental verification of the theory on the inverse Smith–Purcell effect at a submillimeter wavelength (1992)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 61 (1992), S. 870-872

    Topics: Physics
    Notes: The inverse Smith–Purcell effect is a candidate for laser-driven linacs utilizing the interaction between laser light and an electron beam traveling just in front of a metallic grating. We have performed experiments to study electron energy spread as a function of electron beam position above the grating. A submillimeter wave laser (CH3F, 496 μm) is used as a driving source. It is found that the energy spread characteristics show exponential decay of the interaction strength (field intensity) in the direction perpendicular to the grating surface, as a classical theory on the effect predicts.

    Threshold carrier density in vertical cavity surface emitting lasers (1995)
    Woodbury, NY : American Institute of Physics (AIP)

    Topics: Physics
    Notes: A combination of spontaneous emission lifetime and spectral measurements is used to estimate the threshold carrier density in small diameter gain guided vertical cavity surface emitting lasers. Differential spontaneous emission lifetimes measured below threshold are extrapolated to a τth=0.4 ns at threshold. The corresponding threshold carrier density is Nth=7.9×1018 cm−3. The measured carrier densities are used to calculate spontaneous emission spectra. These are in agreement with the edge emission spectra obtained on cleaved laser chips. For the measured carrier density, we estimate the threshold gain at the emission wavelength of g=1640 cm−1. © 1995 American Institute of Physics.

    Reflection noise in vertical cavity surface emitting lasers (1993)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 63 (1993), S. 1480-1482 
    Details
    ISSN: 1077-3118
    Source: AIP Digital Archive
    Topics: Physics
    Notes: We describe the effect of back reflections on the relaxation-oscillation peaks of low threshold (〈6 mA), high intrinsic bandwidth (31 GHz) vertical cavity surface emitting lasers. With the largest feedback possible with our experimental arrangement, x=−5.8 dB, the relaxation-oscillation peak breaks up into a series of sharp resonances with the spacing corresponding to the round tip frequency of the external cavity. In contrast to edge emitting lasers, no effect of reflections is observed for feedback levels x〈−12.9 dB. This relative immunity of vertical cavity lasers to reflection noise is expected to be of interest for their applications to fiber communications.

    Chiral wave propagation manifold of the photonic quantum-ring laser (2002)

    Notes: A torus knot model is presented to analyze the chiral wave propagation of photonic quantum-ring lasers in a three-dimensional Rayleigh–Fabry–Perot toroidal cavity. The Rayleigh–Fabry–Perot cavity gives rise to peculiar multichromatic spectra with nonequal intermode spacings. In particular, the knot model analysis suggests a strange three-dimensional effective index ellipsoid for the cavity with a large birefringence of neff3D(z)−neff2D(x,y)(approximate)0.4–0.5. © 2002 American Institute of Physics.

    Evanescent and propagating wave characteristics of the photonic quantum ring laser (2001)

    Notes: We present the wave propagation characteristics of photonic quantum ring lasers with clear evidence of the evanescence-propagation crossover behavior. The data obtained from the fiber probe measurements of 15–36 μm disk size lasers show that the Rayleigh's whispering gallery modes always give rise to the propagation mode, with the crossover ranges of 55–80 μm. The three-dimensional but chiral and broken z-axis symmetry nature of the photonic quantum ring cavity appears to guarantee such a crossover to the propagation in general. © 2001 American Institute of Physics.
