Towards Site-Selective Fabrication of Near-Infrared Emitters in hBN
Tadas Paulauskas, Vakaris Silys, Edgaras Markauskas +5
Spatial control of near-infrared (NIR) emission from hexagonal boron nitride (hBN) would facilitate coupling atomic-scale light sources to photonic structures, yet oxygen-related N…
Symmetry-guided modal control in elliptical femtosecond-laser-written photonic waveguides
Tadas Paulauskas, Ubaid Ur Rehman, Eimantas Dermauskas +1
Few-mode photonic circuits can increase functionality without multiplying waveguide paths, but bends and fabrication errors can mix their transverse modes. We investigate a strateg…
Thermal Decoherence and Population Transfer of MeV Channeling Electrons in Diamond
Tadas Paulauskas
Channeling radiation from MeV-regime electrons is governed by transitions between quantized transverse bound states, but experimental spectra are strongly modified by thermal diffu…
Decay of high-energy electron bound states in crystals
Tadas Paulauskas, Robert F. Klie
High-energy electrons that are used as a probe of specimens in transmission electron microscopy exhibit a complex and rich behavior due to multiple scattering. Among other things,…
