Abstract The terahertz (0.1–10 THz) range represents a fast-evolving research and industrial
field. The great interest for this portion of the electromagnetic spectrum, which lies between …

The research and development of optical metasurfaces has been primarily driven by the
curiosity for novel optical phenomena that are unattainable from materials that exist in nature …

Active control of chirality in artificial media such as metamaterials is fundamental in many
scientific areas, ranging from research into fundamental optical phenomena to the …

Current compact emitter and receiver technologies are generally inefficient and impractical
at terahertz (THz) frequencies between 0.1 and 10 THz. Hence, a gap exists between …

Engineering the chirality of optical microcavities is a central concept of modern photonics to
gain full control the polarization of the confined electromagnetic mode. Here, we …

Photonic bound states in the continuum (BICs) are highly localized optical modes that have
found important applications in lasers, sensors, modulators, and harmonic signal …

A compact circular polarized graphene-based patch antenna is proposed for THz
applications. The proposed antenna consists of a microstrip patch radiator made of …

The generation of circularly polarized laser emission (CPLE) in photonic devices has
attracted increasing attention due to the prospects of using CP light in displaying …

Chiral nanostructures and their optical activity have been attracting great interest. Here, we
designed an enantiomer bolaamphiphile containing a naphthalene moiety (bola-1) and an …

A terahertz (THz) quantum cascade laser (QCL) is an electrically pumped semiconductor
laser based on the inter‐subband electron transitions in a multiple‐quantum‐well …
