Low-power swept-source Raman spectroscopy
Optics Express, 2021 ‘Molecular fingerprinting’ with Raman spectroscopy can address important problems–from ensuring our food safety, detecting dangerous substances, to supporting disease diagnosis and management. However, the broad adoption of Raman spectroscopy demands low-cost, portable instruments that are sensitive and use lasers that are safe for human eye and skin ...

Bifurcation structure of a swept-source laser [PDF]
Physical Review E, 2020 We numerically analyze a delay differential equation model of a short-cavity semiconductor laser with an intracavity frequency swept filter and reveal a complex bifurcation structure responsible for the asymmetry of the output characteristics of this laser.
