  • Optical Neural Networks Using Synthetic Dimensions
    Article - 7 Mar 2023
    A new theoretical study suggests building an optical neural network architecture for deep learning using the concept of a temporal synthetic dimension. The synthetic dimensions are created by the...
  • First Chip-Scale Titanium-Doped Sapphire Laser
    Article - 24 Feb 2023
    The first chip-scale titanium-doped sapphire laser has been developed by a research team at Yale University.
  • 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...
  • The Use of Silicon in Optical Fibers and Optoelectronics
    Article - 27 Jan 2023
    With so many recent developments in silicon-based optoelectronics and fiber optic systems, it seems silicon will be the element not just associated with the technological developments of the past, but...
  • The First Multi-Color Integrated Laser
    Article - 20 Dec 2022
    From the development of efficient quantum cascade lasers that cover most of the mid-infrared region to excimer lasers that provide a range of different UV wavelengths, advances in laser technologies...
  • 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...
  • What is Photoelectron Spectroscopy?
    Article - 31 Oct 2022
    Photoelectron spectroscopy involves the detection of the kinetic energies of photoelectrons emitted following an ionization event. If it is assumed that the emitted photoelectrons do not undergo any...
  • Gamma Ray Generation Using High-Powered Lasers
    Article - 16 Aug 2022
    This article focuses on the concept of gamma rays, their sources and emitters. It then focuses on the presence of gamma rays in the cosmos and how they are generated. Finally, it talks about joint...
  • How a Laser Mode Sensor Will Probe Neutron Star Interiors
    Article - 22 Jun 2022
    A laser mode sensor development by gravitational-wave scientists at the University of Western Australia could be the key to probing beneath the surface of neutron stars. The breakthrough may help...
  • Identifying Drugs in Packaging Using Spectroscopy
    Article - 21 Jun 2022
    Researchers at Shizuoka University in Japan have found a way to use an attenuated total reflection version of terahertz spectroscopy to identify drugs in plastic packaging even for compounds with high...
