  • What is Photothermal Spectroscopy?
    Article - 14 Feb 2023
    A type of optical analytic technique called photothermal spectroscopy is a powerful tool to study heat that is produced as a result of light absorption in a sample that has been exposed to radiation.
  • Recent Research on Quantum Cascade Lasers
    Article - 10 Feb 2023
    Quantum cascade lasers are a type of semiconductor laser that typically emit in the mid-infrared region (~ 4 µm to 10 µm). They are somewhat unusual in comparison to other laser systems in terms of...
  • What is Quantum Microscopy?
    Article - 22 Dec 2022
    Particle manipulation has always been crucial to enhancing scattering and microscopy methods for material studies. In light of this strategy, researchers integrated quantum technology and microscopy...
  • The Future of Mid-Infrared Studies of Distant Galaxies
    Article - 12 Dec 2022
    A special diagnostic tool for determining the physical conditions in the interstellar medium of galaxies is provided by mid-infrared spectra.
  • Using a Maxwell Hamiltonian Theory of Matter to Develop Picophotonics
    Article - 28 Nov 2022
    In order to explain the electrodynamic dispersion of the photon field, a team led by Prof. Zubin Jacob at Purdue University developed a Maxwell Hamiltonian theory of matter along with the quantum...
  • Achieving 'More Signal, Less Background' in Photonics
