Review of Photonic Integrated Optical Phased Arrays for Space Optical Communication

IEEE Access, 2020
A review of photonic integrated optical phased array (OPA) for space optical communication is presented. We review and summarize the typical works of the photonic integrated OPAs with one-dimensional and two-dimensional optical antenna array in recent ...

On-chip Hong-Ou-Mandel interference from separate quantum dot emitters in an integrated circuit [PDF]

arXiv, 2023
Scalable quantum photonic technologies require low-loss integration of many identical single-photon sources with photonic circuitry on a chip. Relatively complex quantum photonic circuits have already been demonstrated; however, sources used so far relied on parametric-down-conversion.

ALD‐Assisted VO2 for Memristor Application

Advanced Engineering Materials, EarlyView.
This work demonstrates a strategy for depositing VOx using thermal atomic layer deposition (ALD) followed by thermal annealing to synthesize VO2. The thin film and core/shell wire memristors exhibit excellent switching performance and are highly sensitive to ambient temperature.

Real-time fast physical random number generator with a photonic integrated circuit.

Optics Express, 2017
Random number generators are essential for applications in information security and numerical simulations. Most optical-chaos-based random number generators produce random bit sequences by offline post-processing with large optical components.

An Examination of Aerosol Jet‐Printed Surface Roughness and its Impact on the Performance of High‐Frequency Electronics

Advanced Engineering Materials, EarlyView.
This study explores aerosol jet‐printed (AJP) surface roughness, its effects on the performance of microwave electronics, and its process contributors. First, an electromagnetic model is vetted for AJP's unique roughness signature. Simulations are built which show process‐induced roughness is as significant as conductor resistivity in driving microwave

Covalently‐Bonded Diaphite Nanoplatelet with Engineered Electronic Properties of Diamond

Advanced Functional Materials, EarlyView.
A novel approach to engineering the electronic properties of diamond is reported on the diaphite nanoplatelet consisting of (11¯${{\bar{1}}}$1) planes of diamond nanoplatelet covalently bonded with graphite (0001) planes. The strong sp3/sp2‐hybridized interfacial covalent bonding induces the electron transfer from diamond to graphite, resulting in a ...

Efficient and Scalable Radiative Cooling for Photovoltaics Using Solution‐Processable and Solar‐Transparent Mesoporous Nanoparticles

Advanced Functional Materials, EarlyView.
Graded refractive index (GRI) structures are prepared from the layer‐by‐layer spray coating of the mesoporous SiO2 nanoparticles, showing high solar transparency and thermal emissivity. Under outdoor conditions, after 50 days, the GRI‐coated photovoltaics show on average 6.65 ± 1.48 °C lower than that of the non‐coated references, maintaining 80.9 ± 8 ...

Monolithically integrated circuits for Optical injection locking of ring lasers with QKD and QPSK applications [PDF]

arXiv, 2023
Optical injection locking of integrated ring lasers promises to be a key technology of the future, but it is still lacking experimental verification. In this paper we present two monolithically integrated photonic circuits that experimentally realize Optically injection locking of ring lasers.
