Free space optics data transmission with bitrate in excess of 10 Gbit s− 1 is demonstrated at
9 µm wavelength by using a unipolar quantum optoelectronic system at room temperature …

Since about one and half centuries ago, at the dawn of modern communications, the radio
and the optics have been two separate electromagnetic spectrum regions to carry data …

We demonstrate mid-infrared ring resonators fabricated in an In 0.53 Ga 0.47 As/InP
materials platform operating at a wavelength of approximately 5.2 μm with quality factors …

The large mid-infrared (MIR) spectral region, ranging from 2.5 µm to 25 µm, has remained
under-exploited in the electromagnetic spectrum, primarily due to the absence of viable …

Free-space optical communication is a very promising alternative to fiber communication
systems, in terms of ease of deployment and costs. Midinfrared light has several features of …

Free-space optics (FSO) in the mid-infrared (mid-IR) contains rich spectral resources for
future ultrahigh-speed wireless communications yet is currently under-exploited. Two …

The initial access in Millimeter wave (mmWave) 5G communications is very challenging and
time consuming. In general, mmWave and terahertz communications require the use of …
