Photonic bandgap microcombs at 1064 nm

February 27, 2024
Author(s)
Gregory Spektor, Jizhao Zang, Atasi Dan, Travis Briles, Grant Brodnik, Haixin Liu, Jennifer Black, David Carlson, Scott Papp
Microresonator frequency combs and their design versatility have revolutionized research areas from data communication to exoplanet searches. While microcombs in the 1550 nm band are well documented, there is interest in using microcombs in other bands

Enhancement of Optical Absorption by Oxygen Plasma Treatment in Carbon Nanotube-based Black Paint Coating

July 5, 2023
Author(s)
Atasi Dan, Joel Rutkowski, Patrick McArdle, Erica Freire Antunes, Nathan Tomlin, Malcolm White, Michelle Stephens, John H. Lehman
Effect of oxygen (O2) plasma treatment on reflectance properties and surface morphology of CNT-based paint was investigated. We demonstrate a specular reflectance less than 0.10% and hemispherical reflectance less than 2.5% throughout the UV-Vis-NIR range.

Extremely broadband calibrated bolometers and microbolometer arrays for Earth radiation budget measurements

Michelle Stephens, Chris Yung, Nathan Tomlin, Dave Harber, Cameron Straatsma, Atasi Dan, Erica Freire Antunes, Peter Pilewskie, Odele Coddington, John H. Lehman
The Earth radiation budget, a 40-year data record of the balance between solar radiation reaching the Earth and the amount absorbed, reflected, and emitted from the Earth, is a key climate record for determining whether the Earth is warming or cooling. The
