We study the energy propagation in subwavelength waveguides and demonstrate that the mechanism of material gain, previously suggested for loss compensation, is also a powerful tool to manipulate dispersion and propagation characteristics of electromagnetic pulses at the nanoscale. We show theoretically that the group velocity in lossy nano-waveguides can be controlled from slow to superluminal ...
متن کاملSuperluminal Velocity To Time Machines ?
Various experiments have shown superluminal group and signal velocities recently. Experiments were essentials carried out with microwave tunnelling [1], with frustrated total internal reflection [2], and with gain-assisted anomalous dispersion [3]. According to text books a superluminal signal velocity violates Einstein causality implying that cause and effect can be changed and time machines k...
متن کاملSuperluminal Signal Velocity
It recently has been demonstrated that signals conveyed by evanescent modes can travel faster than light. In this report some special features of signals are introduced and investigated, for instance the fundamental property that signals are frequency band limited. Evanescent modes are characterized by extraordinary properties: Their energy is negative, they are not directly measurable, and the...
متن کاملDirect measurement of superluminal group velocity and signal velocity in an optical fiber.
We present an easy way of observing superluminal group velocities using a birefringent optical fiber and other standard devices. In the theoretical analysis, we show that the optical properties of the setup can be described using the notion of "weak value." The experiment shows that the group velocity can indeed exceed c in the fiber; and we report the first direct observation of the so-called ...
متن کاملSlow to superluminal light waves in thin 3D photonic crystals.
Phase measurements on self-assembled three-dimensional photonic crystals show that the group velocity of light can flip from small positive (slow) to negative (superluminal) values in samples of a few mum size. This phenomenon takes place in a narrow spectral range around the second-order stop band and follows from coupling to weakly dispersive photonic bands associated with multiple Bragg diff...
