From the technological perspective, the demonstration of the topological chip is the result of fabrication, controlling and packaging of large-scale photonic circuits, and the completeness of measurements. One fabricated and packaged chip is shown in Fig. 1b–d. The high-level controllability and ...
Here we focus on passive imaging in the visible to thermal wavelengths. We define panchromatic imagery as a single image acquired over a single (potentially broad) spectral channel; multispectral imagery as the simultaneous acquisition of tens of channels; and hyperspectral imagery as the simultaneous...
In general, from the perspective of the ground-based optical receiver, both classical and quantum communications rely on the sensitivity and speed of the detector to determine the ultimate distance and data rate. Among several existing SPDs, the superconducting nanowire single-photon detector (SNSPD)...
Lidar systems are based on laser ranging, which measures the distance between a sensor and target based on half the elapsed time between the emission of a pulse and the detection of a reflected return (Baltsavias, 1999). Critical to the adoption of lidar as a survey tool, however, is the...
they only focus on the functionality and performances of metasurfaces and do not comment on the practical usage of recent metasurface-integrated optical platforms. From this perspective, this review presents a careful selection of integrated metasurfaces that are expected to be employed in near-future...
4. LiDAR systems can work in darkness and offer high resolution and high accuracy thanks to the short wavelength of light5. Small-form-factor LiDARs with single-photon avalanche diode arrays6,7,8have started to be featured in smartphones and other consumer electronics; however, their ranges ...
We present a compact and lightweight 1.5 m lidar using a free-running single-photon detector (SPD) based on a multi-mode fiber (MMF) coupling InGaAs/InP negative feedback avalanche diode. The ultimate light detection sensitivity of SPD highly reduces the power requirement of the laser, whilst...
