Superoscillations are making a growing impact on an ever-increasing number of real-world
applications, as early theoretical analysis has evolved into wide experimental realisation …

Superoscillatory (SO) imaging is an emerging technique to super-resolve unlabeled objects
in the far-field. Reducing the full width at half-maximum (FWHM) of the main beam is a …

Talbot length, the distance between two consecutive self-image planes along the
propagation axis for a periodic diffraction object (grating) illuminated by a plane wave …

We report an unusual type of Talbot effect. Unlike the traditional Talbot effect taking place in
the lateral direction, this ring-shaped Talbot effect takes place for beams with certain …

Speaking about the oblique Talbot effect, one usually assumes the case when the diffraction
grating is illuminated by a plane wave at an angle, while the screen for observing the …

Light beams with Orbital Angular Momentum (OAM) are explored in applications from
microscopy to quantum communication, while the Talbot effect revives in applications from …

Spectral resolution is an important parameter of a wavemeter. Here, we propose a compact
wavemeter based on two gratings and signal processing. By applying the Multiple Signal …

Optical superoscillation, a phenomenon that the local optical field can oscillate much faster
than that allowed by its highest harmonic, can significantly overcome the Abbe diffraction …

Multi-mode interference in waveguides and free space. The chapter deals with the modes in
the waveguides or free space which propagates with different velocities and propagation …

At present, the mutual restriction between the spectral resolution and the dynamic range
limits the further improvement of the spectral property of Talbot spectrometer. This mutual …
