We demonstrate a 64-times multiplication of a mode-locked laser's 217 MHz pulse repetition rate using an integrated <tex>$\mathrm{S}\mathrm{i}_{3}\mathrm{N}_{4}$</tex> interleaver with a compact 8.5 mm x 1.7 mm footprint, for the generation of a low-noise 14 GHz microwav...
These include phase-coherent optical communication using quadrature-amplitude-modulation, and also record-low phase noise microwave sources based upon optical comb techniques. In this work, the first, chip-based Brillouin laser is demonstrated. It features high-efficiency and single-line operation with ...
ADI’s AD5770R is a 6-channel, 14-bit resolution, low noise, programmable current output DAC for photonics control applications. Included is a 1.25 V, on-chip voltage reference, a 2.5 kΩ precision resistor for reference current generation, and more....
Although holding great promise for low noise, ease of operation and networking1, useful photonic quantum computing has been precluded by the need for beyond-state-of-the-art components, manufactured by the millions2,3,4,5–6. Here we introduce a manufacturable platform7for quantum computing with...
Chip that entangles four photons opens up possibility of inviolable quantum encryption Unlike classical encryption, which relies on mathematical algorithms, quantum encryption assures security based on physical principles. Detection of espionage or interference is guaranteed by unavoidable alteration of the ....
From the perspective of the transmit side, link linearity and high RF output power over wide bandwidth are more important than noise. On the other hand, from the perspective of the receiving end, low noise and high dynamic range are of utmost importance. The RF noise figure of the RoF ...
We review a novel paradigm that has emerged in analogue neuromorphic optical computing. The goal is to implement a reservoir computer in optics, where information is encoded in the intensity and phase of the optical field. Reservoir computing is a bio-in
