We present experimental observations of exact dynamic localization of an optical beam in a
periodically curved AlGaAs waveguide array. The dynamic localization of the beam is …

A semi-analytical method for the S-parameter calculations of an N× M multimode
interference coupler (MMI coupler) is presented. The proposed semi-analytical method is …

An asymptotic study of the effective-index method for the analysis of rectangular-core

We show that a dielectric nanowire (NW) with a rectangular cross section can effectively be
modeled as a Fabry-Perot cavity formed by truncating a dielectric slab waveguide. By …

Modal index and normalized index are commonly used in the study of semiconductor
waveguides to model the performance of photonic integrated circuits. These indices are …

We demonstrated the continuous-wave operation of a resonantly pumped Er: YAG single-
mode channel waveguide laser with diffraction-limited output and nearly quantum defect …

A planar slow-wave structure consisting of a planar helix with straight-edge connections has
been studied in the context of application in traveling-wave tubes. The effects of several …

The approximations involved in the effective-index method for analyzing the vector modes of
rectangular-core dielectric waveguides are examined in detail. It is shown that the effective …

Integrated single photon sources are essential elements in quantum computing, simulation,
communication, and photonic neural networks. The directional radiation and scattering of …
