Small and Large Signal Analysis of Terahertz Generation from InN nnn Structures with Free-Carrier Grating
نویسنده
چکیده
Electron transport in long (up to 15 μm) InN nnn structures is theoretically investigated by the Monte Carlo particle technique at low lattice temperatures when optical phonon emission is the dominating scattering mechanism. It is shown that at constant bias a free-carrier grating can be formed inside the n-region. Such a grating is found to be responsible for microwave power generation in the THz frequency range. The generation mechanism is similar to that in submicron nnn structures under quasiballistic transport conditions.

Generation of High Efficient Quasi-Single-Cycle 3 and 6THZ Pulses using Multilayer Structures OH1/SiO2 and DSTMS/SiO2
We propose that high efficient terahertz (THz) multilayer structures are composed of DSTMS/SiO2 and OH1/SiO2 at 3 and 6THz frequencies. We show that the efficiencies of these structures are higher than DAST/SiO2 structure in both of 3 and 6THz frequencies. OH1/SiO2 structure at 6THz has an efficiency as large as 10-1; at 3THz frequency, DSTMS/SiO2 structure has an efficiency as large as 10-...
متن کاملSub-THz Carrier Frequency Generation Stabilized by Mach-Zehnder Interferometric Phase Detection Scheme
We propose a Mach-Zehnder interferometric phase detection for low phase noise subterahertz (THz) carrier frequency generation. In this scheme, phase fluctuation between two optical signals can be detected as the interference between their optical sidebands. Experimental result shows that, by controlling the interference to be constant, the phase noise is successfully reduced, which indicates ef...
متن کاملActive terahertz beam steering by photo-generated graded index gratings in thin semiconductor films.
We demonstrate active beam steering of terahertz radiation using a photo-excited thin layer of gallium arsenide. A constant gradient of phase discontinuity along the interface is introduced by an spatially inhomogeneous density of free charge carriers that are photo-generated in the GaAs with an optical pump. The optical pump has been spatially modulated to form the shape of a planar blazed gra...
متن کاملTerahertz Radiation from Nonpolar InN Due to Drift in an Intrinsic In-Plane Electric Field
A sinusoidal dependence of the sand p-polarized terahertz (THz) emission on sample rotation angle in mand a-plane InN has been observed using ultrafast pulse excitation at a moderate pump fluence of 1 J/cm. The angular dependence is attributed to carrier drift in an intrinsic in-plane electric field parallel to the c-axis induced by stacking fault-terminated internal polarization at wurtzite do...

We report on theoretical investigation of graphene based Field Effect Transistor (FET) structures for resonant absorption of terahertz (THz) radiation by the plasmons excited in the high sheet concentration and high carrier mobility active layers. Metallic grating gates with varying periods were used to couple the THz radiation into the plasmons in the active region of the devices. Such grating...
