The orbital angular momentum (OAM) of light has been implemented as an information
carrier in OAM holography. Holographic information can be multiplexed in theoretical …

Structured light, also known as tailored light, shaped light, sculpted light, or custom light,
refers to a series of special light beams with spatially variant amplitudes and phases …

Third-order nonlinear optical effects were proposed for simultaneous speed modulation of
optical and mechanical waves in bismuth telluride nanostructures assisted by an optical two …

Group IV light sources with vertical emission and non-zero orbital-angular momentum (OAM)
promise to unlock many novel applications. In this report, we demonstrate cylindrically …

Compact vortex beam emitters have emerged as new light sources for novel applications in
areas including spectroscopy, particle manipulation, and communications. Reported devices …

Various excitation-induced loss mechanisms have been identified during the development
of direct-gap semiconductor lasers. Recently, indirect-gap laser sources, particularly …

Control over the shape and polarization of the beam emitted by a laser source is important in
applications such as optical communications, optical manipulation and high-resolution …

We demonstrate the operation of a tunable Vernier filter at a mid-infrared wavelength of
approximately 1.95 μm. To enable efficient tuning through the thermo-optic effect, the filter is …

Germanium (Ge) is a promising candidate for a CMOS compatible laser diode. This is due to
its compatibility with Silicon (Si) and its ability to be converted into a direct band gap material …

Symmetries of waveguides determine fundamental properties of photons such as mode
profiles, polarisation, and effective refractive indexes as well as practical properties affecting …
