The discovery of new materials and their efficient syntheses is a fundamental goal of
chemistry. A related objective is to identify foundational and rational approaches to enhance …

After a review of the basic concepts of slow and fast light, recent advancements based on
nonlinear wave‐mixing processes are described. As a nonlinear medium, the authors focus …

Previously, we had proposed a gravitational wave detector that incorporates the white-light-
cavity (WLC) effect using a compound cavity for signal recycling (CC-SR). Here, we first use …

Speed manipulation of optical pulses is a very attractive research challenge enabling next-
generation high-capacity all-optical communication networks. Pulses can be effectively …

We propose and analyze a superluminal ring laser gyroscope (RLG) using multilayer optical
coatings with huge group delay (GD). This GD assisted superluminal RLG can measure the …

The effect of gravitational waves (GWs) has been observed indirectly, by monitoring the
change in the orbital frequency of neutron stars in a binary system as they lose energy via …

This paper comprehensively investigated noise characteristics of superluminal propagation
based on low-noise single-frequency Brillouin lasing oscillation with the aid of a population …

Sub-band energy levels induced photo-conduction mechanisms play a significant role in the
extension of the response spectra within a photodetector. Herein, we reported a PbZr 0.32 Ti …

We demonstrate experimentally slow and fast light effects achieved simultaneously using
Raman gain and pump depletion in an atomic vapor. Heterodyne phase measurements …

Recently, a tunable bandwidth white light cavity (WLC) was demonstrated by using an
anomalously dispersive intra-cavity medium to adjust a cavity linewidth without reducing the …
