We experimentally demonstrate that 2D Airy wave packets can produce intense curved two-color filaments that emit terahertz (THz) radiation with unique characteristics. Due to the curvature of the plasma channel, THz waves, emitted from different long

Optics manufacturing technology is predicted to play a major role in the future production of integrated photonic circuits. One of the major drawbacks in the realization of photonic circuits is the damage of optical materials by intense laser pulses.

Tornado waves (ToWs) [1] were recently introduced theoretically as a new type of structured light that twists and accelerate both over the radial and the angular dimensions. Tornado waves are comprised by superimposing cylindrically symmetric acceler

Two-color laser filamentation constitute one of the most convenient and efficient sources of pulsed ultra-broadband terahertz (THz) radiation. In this approach, a Gaussian ultrashort laser pulse together with its second harmonic are focused into a ga

We report on THz generation from curved filaments produced by 2D Airy wave packets. Due to the curvature of the plasma channel, non-concentric THz beams with different polarizations are generated.

We experimentally generate Tornado Waves using a single phase modulation device. We show that, by applying spatial multiplexing techniques, such complex superimposing fields that carry orbital angular momentum of opposite handedness can be efficientl

Nanoimprint lithography (NIL) is a technique suitable for the mass production of micro-optical elements using a mould. One drawback, however, is that the materials used in NIL have low laser-induced damage threshold (LIDT). Here, we present our resul

We present a novel optical beam steering technique (OBST) for fiber to free-space to fiber coupling schemes on optical breadboards, which uses glass wedge pairs and plates to correct for angular and translational misalignments respectively. This tech

We present the theoretical analysis of a novel optical beam steering technique (OBST) for fiber to free-space to fiber coupling schemes on optical breadboards. This technique uses glass wedges and plates to correct misalignments in the position and a
