THz photomixing : comparison between horn and spiral antennas

Emilien Peytavit, Tahsin Akalin, Jean-Francois Lampin, Francis Hindle, Chun Yang, Gaël Mouret

We report our investigation on low-temperature-grown GaAs THz photomixers using two different kind of antennas: silicon lens coupled spiral antenna and transverse electromagnetic horn antenna. We demonstrate that the horn radiates more power than the spiral above 600 GHz and at 2 THz the...

Three-dimensional Monte Carlo study of three-terminal junctions based on InGaAs/InAlAs heterostructures

T. Sadi, F. Dessenne, Jean-Luc Thobel

We apply a three-dimensional (3D) semiclassical ensemble Monte Carlo simulation method to study T-branch junctions based on InGaAs/InAlAs heterostructures and obtain an accurate insight into the physics behind the operation of such structures. Electron transport in these devices is investigated and...

Defect modes in one-dimensional anisotropic photonic crystal

Noama Ouchani, Driss Bria, Bahram Djafari-Rouhani, Abdlekarim Nougaoui

We theoretically analyze the defect states in a single-defect photonic crystal composed of anisotropic dielectric materials. This structure can trap light of a given frequency range and filter only a certain frequency light. It is shown that the defect modes appear as peaks in the transmission...
