Celebrating women in optics, photonics, and quantum
Happy International Women's Day! Laser Focus World is proud to feature the work of so many women within the optics/photonics/quantum community, and to celebrate International Women's Day we’d love to share some of our favorite pieces so far from 2025:
Andrea Armani, Ellison Medical Institute and University of Southern California
This episode of Following the Photons: A Photonics Podcast features Dr. Andrea Armani, senior director of engineering and physical sciences at the Ellison Medical Institute and longtime professor at the University of Southern California. She talks about her new career venture with the Ellison Medical Institute, her love of teaching and mentoring engineering students, her perspectives on the photonics industry, and what the future holds:
Maria Chekhova, Max Planck Institute for the Science of Light
Maria Chekhova, whose group at the Max Planck Institute for the Science of Light focuses on quantum radiation, and collaborators showed that using a bright squeezed vacuum to generate high harmonics enhances their yields—compared to classical coherent light—and provides a route to probe material properties beyond the damage threshold:
Angela Demetriadou, University of Birmingham
A new theory developed by Angela Demetriadou and her colleague Benjamin Yuen at the University of Birmingham explains how light and matter interact at the quantum level:
Hui Deng, University of Michigan
Hui Deng, a professor of physics and electrical and computer engineering at the University of Michigan, and her team demonstrated that cavity-enhanced Floquet engineering significantly improves the efficiency and speed of integrated optical communications:
Natalie Fardian-Melamed, Columbia University
Natalie Fardian-Melamed, a postdoctoral researcher in the Department of Mechanical Engineering at Columbia University, and colleagues discovered photon avalanching nanoparticles are supersensitive to mechanical force—and nanosensors they went on to create are poised to redefine what’s possible in terms of sensitivities and dynamic ranges of optical force sensors:
Huihong Qian, Scanlab
Huihong Qian, who is in business development at Scanlab GmbH, describes tabless battery technology that offers a route to increase the energy density of battery packs, and how laser cutting via galvanometer-based scan system offers a manufacturing solution:
Mateja Lampe Rupnik, Red Pitaya
This episode of Following the Photons: A Photonics Podcast features Mateja Lampe Rupnik, CEO of Red Pitaya and advisory CFO to its parent company, Instrumentation Technologies. She has many years of experience in tech industries, and offers the unique perspectives she’s gained since joining the photonics realm, including on the growing and evolving roles of women in STEM:
Hele Savin, Aalto University
Hele Savin, a professor of micro- and nanoelectronics at Aalto University, and her research team created a germanium infrared photodiode that’s 35% more responsive at 1.55 µm—a common wavelength for telecommunications—than its other germanium and indium gallium arsenide counterparts:
Birgit Stiller, Max Planck Institute for the Science of Light and Leibniz University Hannover
Birgit Stiller, head of the Quantum Optoacoustics research group at the Max Planck Institute for the Science of Light and a full professor at Leibniz University Hannover, is leading work pioneering building blocks for optoacoustic neural networks:
Olivia Wheeler-Williams, Edmund Optics
This episode of Following the Photons: A Photonics Podcast features Dr. Olivia Wheeler-Williams, coatings development manager at Edmund Optics, who has been named a 2025 Optica Ambassador, a position that allows her to help strengthen ties between academia and industry. She chats about her work at Edmund, being a mentor, and the importance of diversity in optics:

Sally Cole Johnson | Editor in Chief
Sally Cole Johnson, Laser Focus World’s editor in chief, is a science and technology journalist who specializes in physics and semiconductors. She wrote for the American Institute of Physics for more than 15 years, complexity for the Santa Fe Institute, and theoretical physics and neuroscience for the Kavli Foundation.

Justine Murphy | Multimedia Director, Digital Infrastructure
Justine Murphy is the multimedia director for Endeavor Business Media's Digital Infrastructure Group. She is a multiple award-winning writer and editor with more 20 years of experience in newspaper publishing as well as public relations, marketing, and communications. For nearly 10 years, she has covered all facets of the optics and photonics industry as an editor, writer, web news anchor, and podcast host for an internationally reaching magazine publishing company. Her work has earned accolades from the New England Press Association as well as the SIIA/Jesse H. Neal Awards. She received a B.A. from the Massachusetts College of Liberal Arts.

Lee Dubay | Managing Editor
Lee Dubay is managing editor for Laser Focus World. She is a seasoned editor and content manager with 20 years of experience in B2B media. She specializes in digital/print content management, as well as website analytics, SEO, and social media engagement best practices.
