Background

Ultraviolet (UV) based technology has great promise for indoor and outdoor military and commercial applications, especially communications. This is based on the significant recent progress in deep UV solid state devices (LEDs and APDs), the unique atmospheric channel characteristics (non-line of sight scattering, solar blind operation), and successful experimental UV test-beds.

Workshop Program

This one-day workshop is sponsored by the Army Research Office (ARO) and the Army Research Laboratory (ARL). The workshop will bring together a select group of R&D leaders from academia, industry, and government. This small (about 30-40 anticipated attendees) invited participation workshop will consist of several plenary talks and panels, with ample time for discussion of the state of the art, issues, applications, and future R&D directions.

The workshop will largely focus on the following areas:

(1). UV device technologies, such as sources, filters, detectors, and optical lens and antennas

(2). UV line-of-sight and non-line-of-sight propagation, scattering, and communication link characterization

(3). UV communication systems

(4). Other UV applications, such as sensing and imaging
