Strain-induced InGaAs/InAlAs superlattices for terahertz radiation
D. S. Ponomarev, A. E. Yachmenev, S. S. Pushkarev +7
We study the influence of residual strain in InGaAs/InAlAs superlattice (SL) on the ultrafast photocarrier dynamics under femtosecond laser excitation. We propose and fabricate a n…

Shaping the spectrum of terahertz photoconductive antenna by frequency-dependent impedance modulation
D. V. Lavrukhin, A. E. Yachmenev, A. Yu. Pavlov +8
In this paper, we report on an approach for shaping the spectra of THz pulse generation in photoconductive antennas (PCAs) by frequency-dependent impedance modulation. We introduce…
