Continued development in the areas of communication, security, medicine, and safety is
calling for terahertz‐wave technologies to evolve beyond laboratory research and into the …

We introduce a 1× N integrated power splitter for the multimode photonics platform. The
device converts an input laser beam into a higher-order mode beam, which afterwards is …

A frequency-tunable gyrotron with multiband radiation has been designed, manufactured,
and investigated experimentally. The frequency tuning scheme utilizing transverse modes …

The article is devoted to issues related to the propagation and transformation of vortexes in
the optical range of frequency. Within the framework of the traditional and modified model of …

In this study, we proposed a hologram calculation method for light-in-flight recording by
holography (LIF holography). First, we simulated the behavior of ultrashort pulsed light on …

In this paper we discuss two strategies to achieve wideband light generation through
intermodal nonlinear parametric processes in multimode integrated waveguides. We outline …
