Optical demultiplexer device operating in the visible spectrum

Optical Repeater Assisted Visible Light Device-to-Device Communications

Device-to-device (D2D) communication is considered a promising technique to provide wireless peer-to-peer communication services. Due to increasing demand on mobile services, available spectrum for radio frequency (RF) based communications becomes scarce. Recently, visible light communications (VLC) has evolved as a high speed wireless data transmission technology for indoor environments with a...

Crosstalk and Noise Characteristics of Non-linear Optical Loop Mirror Demultiplexer and Terahertz Optical Asymmetric Demultiplexer

Crosstalk and noise characteristics of non-linear all optical loop mirror (NOLM) demultiplexer and terahertz optical asymmetric demultiplexer (TOAD) are investigated in this paper. The best demultiplexing conditions are studied in order to minimise the crosstalk and noise, and to achieve reduced power penalty for both all-optical demultiplexing schemes.

Augmenting Physical Objects by a Ubiquitous Spatial Projection Display Operating in the Visible Light Spectrum

Recently, mobile projector applications have become cutting-edge research for augmenting the physical world in a ubiquitous manner. By coupling a small projector with sensing devices, one can create a system that is able to recognize the physical world and provide appropriate augmentation via projection in real time. A popular sensing device for projection systems is a camera because it can acq...
