“…Increasing collection area for a given bandwidth and improving sensitivity are therefore important goals. Detectors can be optimized to maximize area [11], and detector types with low capacitance (such as Membrane Semiconductor Metal (MSM) devices [16]) can also be considered. In addition receiver gain mechanisms can also be beneficial.…”

Wireless communications is facing the challenges of a predicted 'explosion' in the number of wireless devices, demand for higher capacity, and the need to reduce power consumption in order to lower greenhouse gas emissions. Optical Wireless (OW) communications may have a part to play in helping to achieve these aims.High speed line of sight optical wireless systems have the potential to provide a low complexity alternative to high frequency RF wireless communications, and may offer lower energy consumption. Visible light communications is also a growing area of interest. Low energy solid-state lighting sources can be modulated to provide data communications, and this can augment the communications provided by other wireless techniques.In this paper we review progress in these areas. Examples and results from systems will be reported, together with future directions and challenges..

“…Anti-reflective (AR) structures have found applications in various fields such as light detection and ranging (LIDR) [1][2][3][4], photovoltaic systems [5][6][7], smart windows [8][9][10] and laser structures [11,12]. Several researchers have proposed different AR structures that can be used in operational technologies that focus on reducing reflections from the device surface [13][14][15].…”

Nowadays, the anti-reflective (AR) structures are essential in many applications like display screens, photovoltaic structures and light detection and ranging. Traditionally, the AR surfaces are almost multilayer (ML) structures to minimize the reflection value by producing the destructive interference of reflected light beams at the layers' interfaces. In the new and advanced AR surfaces, nanostructures (NS) are proposed and used for minimizing the reflection. In this paper, we propose a temperature-switchable AR-ML-NS, based on vanadium dioxide (VO2) phase transition from semiconductor to metallic state around the critical temperature of 68º C. Here, a pyramidal NS of VO2 is considered on top surface of a ML which minimizes the light reflection of the structure. While some AR structures may work in some restricted light wavelengths, here our proposed structure's AR wavelength region can be tuned between the visible and near-infrared (NIR) region through the thermal phase transition of VO2. VO2 phase control leads to a temperature-switchable AR structure, which is of great importance for investigating different switchable AR structures.
