We performed optical pulse propagation experiments in a system in which two ultrahigh-Q
silica microspheres of different diameters were coupled in tandem to a fiber taper to yield …

Ever since the first experimental demonstration was reported in 2000, the interest in
metamaterials and left-handed media that exhibit a negative refractive index has increased …

The dispersion relation in a system of a fiber taper coupled with a microsphere is
investigated. On the undercoupling condition, in which the coupling strength between the …

We discuss the mechanism of fast and slow light generation when optical pulses propagate
through a fiber taper coupled to an ultrahigh-Q microsphere system in the time domain. Fast …

We analyzed fast and slow light in a fiber-ring resonator in a framework of weak-value
measurements, obtaining the explicit form of the interaction Hamiltonian. Here, we fully …

We theoretically revisit the problem of the propagation of coherent light pulses through a
linear medium when the carrier frequency of the pulses coincides with the minimum of a …

The traversal times for an electromagnetic pulse traversing a slab of dispersive and
dissipative material with negative dielectric permittivity (ϵ) and magnetic permeability (μ) …

We show that arrival times for electromagnetic pulses measured through the rate of
absorption in an ideal impedance matched detector are equivalent to the arrival times using …

We develop the concepts of net Goos–Hänchen (GH) shift and reshaping shift, and apply
these concepts to lateral beam shift arising from k (wavenumber) domain dispersion …

We experimentally examined the propagation of a Gaussian-shaped temporal pulse through
a serial array of ring resonators, truncating the pulse before its peak. We observed the …
