“…In recent decade, semiconductor devices in the UV range have been developed for LEDs sources and avalanche photodiodes (APD) [108,109]. The first ever LED-based OSC research was reported in [110]- [112]. The system consisted of 10 LEDs at 274 nm wavelength, where each unit has a 24-element array, producing a total optical power of 40 mW and a Perkin-Elmer PMT module combined with a solar blind filter to achieve a high solar noise rejection ratio.…”

“…Solar blind ultraviolet communication systems can provide short to medium range non line-of-sight and line-of-sight links which are covert and insensitive to meteorological conditions. [1] Operation in the solar blind region provides zero background conditions and strong scattering interactions. Scattering provides the basis for transferring information when non line-of-sight conditions exist.…”

“…The region between 200 nm and 280 nm is referred to as the solar blind region. [1] In this region, radiation interacts strongly with atmospheric constituents (molecules and aerosols) resulting in some very unique properties. At wavelengths greater than 280 nm, background radiation is significant and constraints associated with most optical systems apply.…”

Solar blind ultraviolet communication systems can provide short to medium range non line-of-sight and line-of-sight links which are covert and insensitive to meteorological conditions. These unique properties endow solar blind ultraviolet communication systems increasing applications. While optical filters are key components of these solar blind ultraviolet communication systems. Although filters can be designed in different forms, thin-film interference narrowband filters are widely adopted. In this paper, we make use of NCNBIF, which was so-called nonconventional narrowband interference filters proposed by Jerzy Ciosek firstly, to design ultraviolet narrow-band interference filters. Generally, classical narrow-band interference dielectric filters, such as Fabry-Pérot filters, have a half-wave-thickness spacer layer. In contrast with a classical interference filter, the NCNBIF does not have a half-wave-thickness spacer layer. This spacer layer of NCNBIF consists of two different materials. This new kind of film system (NCNBIF) is synthesized by using needle optimization technique, and possesses desired spectral characteristics.

“…Wireless communication using diffuse mid-UV is enabled by two unique phenomena: the atmosphere absorbs solar radi ation between 200 nm and 280 nm, and UV generated on the earth's surface is strongly scattered [1]- [3]. Because mid-UV radiation from the sun is absorbed by the atmosphere, receivers on the ground operate in a nearly noise-free environment.…”

Communication using mid-ultraviolet radiation be tween 200 nm and 280 nm has received renewed attention due to advancements in UV LED emitters and unique propagation characteristics at these wavelengths. Atmospheric gases absorb light at mid-UV so that receivers or sensors operating on the earth's surface receive no interference from solar radiation. This so-called "solar-blind" region of the spectrum allows the use of single-photon detection techniques. Further, UV light is strongly scattered by molecules in the air, enabling non-Iine-of-sight (NLOS) communication. We extend previous work in this area by incorporating angle-dependent Mie scattering into one of the standard propagation models, in an effort to include the effects of aerosols. Experimental results from outdoor measurements using a fog generator are also presented.
