Photonic Generation of Broadly Tunable Microwave Signals Utilizing a Dual-Beam Optically Injected Semiconductor Laser

open access: yesIEEE Photonics Journal, 2011
We propose and study photonic generation of broadly tunable microwave signals utilizing a dual-beam optically injected semiconductor laser. By injecting a slave laser with two detuned master lasers at the stable locking states, microwave signals with ...

Dual-beam optical profilometer

open access: yesConference on Lasers and Electro-Optics, 1982
The ability to measure surface profiles and determine the statistical properties of surfaces is important for many applications. Examples can be found in fields as diverse as magnetic storage and optical fabrication. In this paper, we will describe the development of a novel noncontact optical profilometer.

Investigating transcription factor dynamics in health and disease using FRAP

open access: yesFEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...
