  • Photonic solutions for generating free space millimeter radiation is a fast developing field that combines optoelectronics and RF domains but has many challenges. Here the authors present a quantum cascade laser (QCL) based solution for THz laser emission and millimeter wave generation in a single device.

  • A passively mode-locked quantum cascade laser (QCL) is developed by employing a heterogeneous gain medium and integrating graphene saturable absorbers along the entire QCL waveguide. Self-starting optical pulses of 4.0 ps are electrically generated in the 2.30–3.55 THz frequency range.

  • Polaritons in 2D materials offer the possibility to confine and manipulate light in the terahertz (THz) range. Here, the authors report the observation of THz elliptic plasmon polaritons in 2D black phosphorus, showing deep subwavelength light confinement and anisotropic polariton propagation.
