Optics Accelerates Deep Learning Computations on Smart Devices
CAMBRIDGE, Mass., Oct. 26, 2022 — MIT researchers have created a method for computing directly on smart home devices that drastically reduced the latency that may cause such devices to be delayed in offering a response to a command or an answer to a question. One reason for this delay is that the connected devices don’t have enough memory or power to store and run the enormous machine learning models necessary for the device to understand a question. Instead, the question is sent to a data center that can be
Theoretical Advancement Enables Unprecedented Wave Control
ITHACA, N.Y., Aug. 20, 2021 — Cornell researchers have proposed a new way to modulate the absorptive and the refractive qualities of metamaterials in real time, and their findings open new opportunities to control, in time and space, the propagation and scattering of waves for...
Metamaterials Work Expands Capabilities for Myriad Applications
ITHACA, N.Y., Aug. 11, 2021 — Researchers at Cornell University have proposed a method to modulate both the absorptive and refractive qualities of metamaterials in real time. Their findings present new opportunities to control — in both time and space — the...
Researchers Control Brain States Via Photoswitchable Molecule
BARCELONA, Spain, July 6, 2021 — A team of scientists in Spain has directly photomodulated brain-state transitions in vivo using a photoswitchable molecule that was developed previously by researchers at the Institute for Bioengineering of Catalonia (IBEC). By applying a...
Microscope Detects Chirality to Make Solid-Tissue Imaging Possible
URBANA, Ill., March 16, 2021 — Researchers at the University of Illinois’ Beckman Institute for Advanced Science and Technology developed a spectroscopic microscope enabling optical measurements of molecular conformations and orientations in biological samples. The device...
Breakthrough in Terahertz Quantum Cascade Lasers
LEEDS, England, Feb. 13, 2020 — A research team from the University of Leeds and the University of Nottingham believe they have found a way of delivering ultrafast modulation, by combining the power of acoustic and lightwaves. They published their findings in Nature...
Modulation Scheme Dramatically Increases Capacity, Range of Next-Generation Fibers
SUNNYVALE, Calif., March 17, 2015 — A new phase-modulation (PM) scheme may have found the “sweet spot” for long-distance communications over next-generation optical fibers. Infinera Corp. of California and BICS SA/NV of Belgium recently completed an extended laboratory...
IR Technique Sees Through Graphene Stacks
BUFFALO, N.Y., Nov. 22, 2013 — An IR technique identifies and characterizes individual graphene layers in a large stack, providing information on the electronic properties of each layer. Such information opens the possibility of graphene-based optical devices for communications,...
Laser mixing generates multifrequency light
SANTA BARBARA, Calif. – A groundbreaking laser mixing technique can manipulate electron-hole collisions to create many frequencies of light simultaneously. This mechanism for ultrafast light modulation has potential applications in high-speed optical communications. ...
