Photonics-Based Oscillator Provides Precise Signals on Compact Chip

Researchers from the University of Colorado Boulder, the National Institute of Standards and Technology, the NASA Jet Propulsion Laboratory, California Institute of Technology, the University of California Santa Barbara, the University of Virginia, and Yale University developed a low-noise microwave generator with a compact, portable form factor by using two-point optical frequency division, a technique for developing high-performance signal sources, with integrated photonic components.

Multicolor Photochromic Fibers Deliver Interactive Wearable Displays

Inspired by photochromic fibers that exhibit fluorescence effects and polymer optical fibers that emit light when coupled with an external source, scientists from Huazhong University of Science and Technology and Nanjing University created a multicolored, uniformly luminescent, photochromic fiber. They prepared the fiber using a mass-producible, thermal-drawing method that allows versatility in the design of the fiber structures. Read Article

Light-Beads Microscopy Reveals New Information About Brain Activity

To better capture and understand neural activity in mice, professor Alipasha Vaziri and his team at The Rockefeller University used large-scale recordings and light-beads microscopy, a volumetric, two-photon imaging technique developed by the Vaziri lab in 2021. LBM increases imaging speed by eliminating the “dead-time” between sequential laser pulses, when no neuroactivity is recorded, and by removing the need for scanning. Read Article

Optical Filters: Application and Design Considerations

Tue, Apr 23, 2024 1:00 PM - 2:00 PM EDT
Optical filters can discretely transmit or reject specific wavelengths or ranges of wavelengths of light. Utilizing this capability in photonics-based instruments creates the need for a better understanding of optical filter design considerations and how specifications influence performance and cost. Craig Hanson of MKS/Newport discusses the fundamental principles of optical coatings and filter types and explains the significance of filter parameters and the benefits of design review. He also explores accessory options and subsystem integration. Next Hanson unveils Newport’s unique manufacturing processes and capabilities for custom optical filters from prototype to high-volume production. Finally, this presentation concludes with an open Q&A, for which Hanson is joined by Mark Roberts, principal thin-film engineer at Newport. Presented by MKS Newport.

Integrated Photonics for Quantum Computing

Tue, May 28, 2024 10:00 AM - 11:00 AM EDT
Realizing photonic quantum technologies, such as an optical quantum computer or a quantum communication link between distant superconducting qubits, will require the development of novel photonic components. Monolithic silicon or silicon nitride photonic platforms are falling short with respect to the requirements of the quantum domain, and it is envisioned that a hybrid solution is needed. In this talk, Christian Haffner of IMEC shortly discusses what hybrid solutions the silicon photonic platform can offer in terms of detectors, sources, and modulators. His primary focus lies on the electro-optical modulator covering the requirements that the quantum world enforces. He compares the classical and quantum theoretical framework, and sketches out what performance metrics a quantum electro-optical modulator needs to fulfill.
