Dynamic metasurfaces including Liquid crystal metasurfaces allow tuning of metasurface functionality also after fabrication.

Metamaterials are artificially structured materials designed to control and manipulate physical phenomena such as light and other electromagnetic waves, sound waves and seismic waves in unconventional ways, resulting in exotic behavior that’s not found in nature. This class of micro- and nano-structured artificial media are predicted to be able to protect …

Vertical-cavity surface-emitting lasers (VCSEL& VECSEL) arrays enable data communication to lidar and military infrared imaging

The illumination source employs different technologies, ranging from lamps to semiconductor light emitting diodes (LEDs) or lasers. The lamp, while straight-forward, is broad-band, bulky, and generally inefficient.   The main wavelengths of interest for illumination are around 808nm, 976m, 1064nm, and 1550nm. The 808nm region offers the best responsivity for …

Europe and US launch Quantum testbeds and Quantum loop to catchup China in Quantum Communications Race

The race to conquer the quantum domain is among the most fiercely competitive in today’s world of technology. One important quantum technology is Quantum key distribution (QKD), that establishes highly secure keys between distant parties by using single photons to transmit each bit of the key.   Quantum cryptography is unbreakable …
