Terahertz Fourier Ptychographic Imaging
Pitambar Mukherjee, Vivek Kumar, Frederic Fauquet +5
High-resolution imaging in the terahertz (THz) spectral range remains fundamentally constrained by the limited numerical apertures of currently existing state-of-the-art imagers, w…

Phase tomography with axial structured illumination
N Goyal, K Khare
Holographic Tomography (HT) or Optical Diffraction Tomography (ODT) provides slice-by-slice information about the refractive index (RI) of three-dimensional (3D) samples and is eme…

Modal complexity as a metric for Anderson localization
Sandip Mondal, Kedar Khare, Sergey E. Skipetrov +2
We present a thorough study of the complexity of optical localized modes in two-dimensional disordered photonic crystals. Direct experimental measurements of complexity were made u…
