Modal decomposition of light has been known for a long time, applied mostly to pattern
recognition. With the commercialization of liquid-crystal devices, digital holography as an …

A quantitative analysis of optical fields is essential, particularly when the light is structured in
some desired manner, or when there is perhaps an undesired structure that must be …

We propose a new method to determine the wavefront of a laser beam based on modal
decomposition by computer-generated holograms. The hologram is encoded with a …

We show how a spatial mode can be extracted from a light beam, leaving the other
orthogonal modes undisturbed, and allowing a new signal to be retransmitted on that mode …

Structured light has become topical of late, where controlling light in all its degrees of
freedom has offered novel states of light long predicted, enhanced functionality in …

Laser Beam Mode Selection by Computer Generated Holograms brings attention to a new
class of optical elements called modans, with applications in laser and fiber optics …

As a proof of concept, we experimentally demonstrate multiplexing of free-space optical
signals in multiple channels labeled with different states of orbital angular momentum. The …

Two-dimensional spatial light modulators (SLMs) modulate one of the properties of an
optical wavefront (amplitude, phase, polarization) as a function of two spatial dimensions …

A procedure for the real-time analysis of laser modes using a phase-only spatial light
modulator is outlined. The procedure involves encoding into digital holograms by complex …
