Research Results
The far-field pattern and its intensity profile during laser oscillation (Fig. 3 (c), (d)) show that the oscillation was achieved with an extremely narrow beam divergence angle (of as low as 0.05°), ...

Non-mechanical Beam Steering and Refocusing Through Liquid Crystal Polarization Gratings
When patterned as diffractive lenses, LCPGs can provide non-mechanical control over beam divergence and variable focusing. These dynamic elements enable a range of applications, such as machine vision ...

A room-temperature mid-infrared detector, reduced-divergence beams, holographic quantum computing, optically cooling molecules, and more
Niels Gregersen and co-workers show that by tapering the nanowires, the divergence of the output beam can be reduced. The proposed nanowire structure consists of a GaAs tip with a tip angle as ...
