Leveraging Quantum Light Within Deployable Quantum Sensors


A technical paper titled “Integrated quantum optical phase sensor in thin film lithium niobate” was published by researchers at Stanford University and NTT Research. Abstract: "The quantum noise of light, attributed to the random arrival time of photons from a coherent light source, fundamentally limits optical phase sensors. An engineered source of squeezed states suppresses this noise a... » read more

Research Bits: June 27


Tunable soliton microcomb Researchers from the University of Rochester and CalTech say they have created the first microwave-rate soliton microcomb that can control the repetition rate at a high speed. Microcombs are frequency combs that can fit on a microchip, which will be useful in photonics. Solitons are solitary waves that keep their shape as they move at a constant speed. The team put an... » read more

Electrically pumped laser transmitter integrated on thin-film lithium niobate


New research paper from Harvard, in collaboration with Freedom Photonics and HyperLight Corp, and with funding from DARPA and Air Force Office of Scientific Research. Abstract "Integrated thin-film lithium niobate (TFLN) photonics has emerged as a promising platform for the realization of high-performance chip-scale optical systems. Of particular importance are TFLN electro-optic modulato... » read more

Power/Performance Bits: Oct. 16


On-chip modulator Researchers at Harvard SEAS and Nokia Bell Labs boosted shrunk down an important component of optoelectronics with an on-chip modulator that is 100 times smaller and 20 times more efficient than current lithium niobite (LN) modulators. Lithium niobate modulators form the basis of modern telecommunications, converting electronic data to optical information in fiber optic ca... » read more

The Bumpy Road To 5G


5G is coming, but not everywhere, not all at once, and not the fastest version of this technology right away. In fact, the probable scenario is that 5G will be rolled out first in densely populated urban areas, starting in 2020 or 2021, with increasingly widespread adoption over the next decade after that. But 5G is unlikely to ever completely replace 4G LTE, just as a smart phone today roll... » read more

Mixing 4G And 5G


5G networks will impact the number and types of ICs in end-user devices and the base stations used to transmit the signals (including the repeaters that rebroadcast those signals). And this is before we begin to consider the technology impact to the infrastructure required to support the data generated in a 5G ecosystem (servers, memory and so on). First, 5G is expected to transmit up to 10 ... » read more
