Laser beam shaping is a venerable topic that enjoyed an explosion in activity in the late
1990s with the advent of diffractive optics for arbitrary control of coherent fields. Today, the …

Nonlinear, ie, multiphoton microscopy is a powerful technique for imaging deep into
biological tissues. Its penetration depth can be increased further using adaptive optics. In …

In this paper we prove that any conformal transformation of a wave can be produced via a
suitably arranged cascade of two, or at most four, discrete phase elements satisfying …

Using custom laser cavities to produce as the output some desired structured light field has
seen tremendous advances lately, but there is no universal approach to designing such …

Combining the specific advantages of high-resolution liquid-crystal-on-silicon spatial light
modulators (LCoS-SLMs) and reflective or refractive micro-electro-mechanical systems …

The number of mirror segments, mirror geometry and orientation are essential parameters
when assessing the beam-shaping capabilities of deformable mirrors. Here, we use a Liquid …

Spatially structured optical modes exhibit a group velocity lower than c, resulting in a
measurable temporal delay with respect to plane waves. Here, we develop a technique to …

We achieve high-resolution sorting of the orbital angular momentum (OAM) of light with two
bespoke diffractive optical elements using the generalized spiral transformation. The …

The multiplication of orbital angular momentum (OAM) modes using optical coordinate
transformation is useful for OAM optical networks, but the scalability of this scheme is limited …

Structured light, where optical beams are tailored in amplitude, phase and polarisation to
some desired profile, has become topical of late, fuelled by the ease at which such fields can …
