Continuously graded parabolic quantum wells with excellent optical performances are used
to overcome the low‐frequency and thermal limitations of square quantum wells at terahertz …

We present a complementary THz metasurface realised with Niobium thin film which
displays a quality factor Q= 54 and a fully switchable behaviour as a function of the …

We present the experimental demonstration of a subpicosecond all-optical THz switch
based on three-dimensional (3D) terahertz meta-atoms. Combining a special design of 3D …

We theoretically study the coherent nonlinear response of electrons confined in
semiconductor quantum wells under the effect of an electromagnetic radiation close to …

Terahertz (THz) and sub-THz frequency emitter and detector technologies are receiving
increasing attention, underpinned by emerging applications in ultra-fast THz physics …

Chiral engineering of TeraHertz (THz) light fields and the use of the handedness of light in
THz light–matter interactions promise many novel opportunities for the advanced sensing …
