Interferometers, devices that can modulate aspects of light, play the important role of modulating and switching light signals in fiber-optic communications networks and are frequently used for gas ...

Wave propagation in slowly varying guiding geometries is of fundamental importance across many disciplines, and can be described in terms of mutually uncoupled quasi-modes. These are a generalization ...

Polaritons in layered materials—including van der Waals materials—exhibit hyperbolic dispersion and strong field confinement, which makes them highly attractive for applications including optical ...

The refraction of acoustic duct waveguide modes emitted from the open end of a semi-infinite rectangular duct by a jet-like exhaust flow is studied theoretically.The problem is formulated as a ...

The first theoretical models of the propagation of an electromagnetic field in a waveguide date back to the second half of the 19th century (Hertz, Debye, Rayleigh). The technological fallout for long ...

A decade ago, researchers at Cornell University reported an analytical device, which they called a zero-mode waveguide, for using light to detect single biomolecules in samples of any concentration.
