Extensions of finite-difference time-domain (FDTD) and finite-element time-domain (FETD)
algorithms are reviewed for solving transient Maxwell equations in complex media. Also …

This report summarizes the results of a study on the properties of five large and five small
size lead tungstate (PbWO4) crystals. Data are presented on the longitudinal optical …

We propose a two-ring resonator configuration that can provide optical switching with high
extinction ratio (ER), large modulation depth (MD) and low switching threshold, and …

We demonstrate a new optical bistability devise by using two Fiber Bragg Gratings (FBG), in
which an erbium-doped fiber (EDF) is inserted to form a nonlinear Fabry–Perot cavity (EDF …

Light propagation in systems of optical cavities coupled to waveguides can be conveniently
described by a general rate equation model known as (temporal) coupled mode theory …

This paper presents a full steady-state analysis of a fiber-optic ring resonator (FORR).
Although in the literature the steady-state response of the FORR has been described, a …

Several types of defect structures in PbWO 4 and CaMoO 4 are studied within the framework
of density functional theory. While PbWO 4 is currently of greater technological interest, we …

Using a sensitive two-color heterodyne pump-probe technique, we investigate the carrier
dynamics of an InP photonic crystal nanocavity. The heterodyne technique provides …

Combining a transfer matrix analysis and slowly varying envelope approximation, we
propose a simple method to describe steady states associated with dispersive multistability …

Light orbiting through total internal reflection within dielectric spheres or disks is called the
whispering gallery mode (WGM). Recently, we have reported anomalously enhanced …
