(English) Being able to secure confidential information is imperative in today’s society, but advancements in quantum technologies pose a potential threat. In response, researchers are developing ...
An important issue in today's information society is the security of data transmission against potential intruders, which always put at risk the confidentiality. Current methods to increase security ...
The combination of unique properties -high electrical mobility, thermal conductivity, transparency and mechanical flexibility- make graphene promising for a wide variety of applications, including ...
In this thesis we have investigated and proposed acoustic superLattices (ASLs) made of periodically poled ZX-cut lithium niobate (PPLN) associated ith coplanar electrodes as an effective alternative for ...
Transparent electrodes (TEs) are the essential elements of many optoelectronic devices such as solar cells, touch screens, organic LEDs, and LCDs. Consequently demand for TEs is growing very steeply and ...
Early detection of microorganisms in environmental and biomedical applications is critical for the effective response to potential pathogenic treats. Most traditional methods and instrumentation for the ...
As health systems fight against epidemics and infectious diseases, new forms of diagnostics need to be developed in order to meet the growing demand for services, often in locations without the necessary ...
A material that is enabling integrated optics is the ferroelectric crystal Lithium Niobate (LiNbO3), which has excellent electro-optical, acousto-optical and nonlinear optical properties. Moreover, it ...
Photonic devices are key to implement future communication and information technologies. Their success is largely determined by our capability to appropriately control light in such devices, especially ...
The focus of this thesis is on the design, development and validation of two novel photonic sensors for the detection and characterisation of industrial and biological samples. The first one is a PSA ...
