This thesis discusses innovative approaches to polymer-based photonic coatings, with the present chapter presenting an overview of developments in this field. The coatings in question can change their topological properties in a reversible, dynamic way when exposed to an external stimulus. This thesis will first describe photoresponsive coatings that change their surface topography and therefor...

The electronic chip industry embodies the height of technological sophistication and economics of scale. The industry mass produces complex circuitry, boasting over one billion components at such low cost that they appear in consumer products. Fabricating inexpensive photonic components by leveraging this mighty manufacturing infrastructure has been the impetus behind the development of silicon...

An important area of photonics concerns the propagation and control of light in nonhomogeneous or nonlinear media. This is an area of great importance due to the range of physical effects to be exploited in the design of devices for communication and computing, as well as in the study of fundamental phenomena. Progress has involved a rich interplay of experiment, modeling, computation and analy...

The multidisciplinary eld of Microwave-Photonics is at the convergence of photonic and microwave or even wireless technologies. In this context, the processing, conversion and transmission of microwaves, as well as high data rate digital and wireless signals, today use broadband optical techniques with many applications. However, the frequency band available is frequently changing with up-to-da...

The U.S. Army’s Future Combat Systems are designed to support the future force with three integrated transformation phases: Concept and Technology Development, Systems Design, Demonstration and Production. The Concept and Technology Developments phase is creating new challenges and opportunities for radio frequency and microwave applications in global positioning, navigation, timing, communicat...

Despite progress towards integrated diamond photonics1–4, studies of optical nonlinearities in diamond have been limited to Raman scattering in bulk samples5. Diamond nonlinear photonics, however, could enable efficient, in situ frequency conversion of single photons emitted by diamond’s colour centres6,7, as well as stable and high-power frequency microcombs8 operating at new wavelengths. Both...

611 Electrons propagating through the bidimensional structure of graphene have a linear relation between energy and momentum, and thus behave as massless Dirac fermions1–3. Consequently, graphene exhibits electronic properties for a two-dimensional (2D) gas of charged particles described by the relativistic Dirac equation, rather than the non-relativistic Schrödinger equation with an eff ective...
