Near optimal graphene terahertz non-reciprocal isolator

Juan Ramon Mosig, Mihai Adrian Ionescu, Clara-Fausta Moldovan, Julien Perruisseau-Carrier, Michele Tamagnone

Isolators, or optical diodes, are devices enabling unidirectional light propagation by using non-reciprocal optical materials, namely materials able to break Lorentz reciprocity. The realization of isolators at terahertz frequencies is a very important ope ...

Strong surface effect on direct bulk flexoelectric response in solids

Alexander Tagantsev

In the framework of a continuum theory, it is shown that the direct bulk flexoelectric response of a finite sample essentially depends on the surface polarization energy, even in the thermodynamic limit where the body size tends to infinity. It is found th ...

Piezoelectric enhancement under negative pressure

Nava Setter, Alexander Tagantsev, Tomas Sluka, Alexander Kvasov, Silviu Cosmin Sandu, Jin Wang

Enhancement of ferroelectric properties, both spontaneous polarization and Curie temperature under negative pressure had been predicted in the past from first principles and recently confirmed experimentally. In contrast, piezoelectric properties are expec ...

Internal optical forces in plasmonic nanostructures

Olivier Martin, Raziman Thottungal Valapu

We present a computational study of the internal optical forces arising in plasmonic gap antennas, dolmen structures and split rings. We find that very strong internal forces perpendicular to the propagation direction appear in these systems. These interna ...

Anomalously thick domain walls in ferroelectrics

Nava Setter, Alexander Tagantsev, Tomas Sluka, Maxim Gureev, Petr Yudin

Using the Landau theory we demonstrate the possibility of unusual, anomalously thick ferroelectric domain walls, where the order parameter rotates with a nearly constant modulus as in ferromagnets. The effect occurs in 90 degrees charged domain walls and i ...

Optical Injection and Lasing Dynamics in Long-Wavelength VCSELs With Intracavity Patterning

Elyahou Kapon, Benjamin Dwir, Alexandru Mereuta, Vladimir Iakovlev, Alexei Sirbu, Andrei Caliman, Zlatko Mickovic, Dalila Ellafi, Christopher Michael Long

We present the static and optical injection response of wafer-fused long-wavelength VCSELs with and without intracavity patterning. It is found that the extra optical cavity patterning increases the gain anisotropy between orthogonal polarization modes, in ...

Characterization, Modeling, and Statistical Analysis of the Electromagnetic Response of Inert Improvised Explosive Devices

The experimental characterization of the electromagnetic (EM) response of a set of inert improvised explosive devices (IEDs) is presented in this paper. The characterization is based on measurements of gain and input impedance of the firing circuits of ine ...

Fundamental limits and near-optimal design of graphene modulators and non-reciprocal devices

Juan Ramon Mosig, Julien Perruisseau-Carrier, Michele Tamagnone

The potential of graphene for photonic applications was evidenced by recent demonstrations of modulators, polarization rotators and isolators. These promising yet preliminary results raise crucial questions: what is the optimal performance achievable by mo ...
