We demonstrated a widely tunable 1-μm optical vortex laser formed from a 0.532-μm optical
vortex pumpedoptical parametric oscillator with a singly-resonant cavity configuration …

We present a high efficiency terahertz (THz) 90°-bend electromagnetic crystal (EMXT)
waveguide using Si-based microelectromechanical systems technology. The 2-D EMXT …

We design an AlGaAs-based terahertz photonic crystal waveguide (PCW) to achieve
terahertz-wave difference frequency generation (DFG) from near-infrared light sources. The …

The phase-matching condition for broadband terahertz (THz) wave generation based on
optical rectification requires that the group velocity of the optical pump beam be equal to the …

In this paper we present a brief analysis of existing materials and structures with quadratic-
nonlinear optical properties that can be used to generate a difference frequency in both THz …

The study on terahertz radiators will not only boost the development of theoretical research,
but also raise severe challenges to solid-state electronics and circuit technology. In the …
