To accomplish the task, they developed angular dispersion control schemes to generate counter-propagating Stokes and pump Bessel light bullets with positive and negative v g, respectively. The phase ...

Coronavirus disease 2019 (COVID-19) has spread to nearly every country globally and caused over 5 million deaths. Following the emergence of the initial strain in Wuhan, China, and its sudden ...

During light scattering, the majority of scattered light undergoes no change in frequency (or energy), in a process referred to as referred to as elastic or Rayleigh scattering. Raman spectroscopy ...

Spatially masked optical Kerr effect (SM-OKE) spectroscopy is a nonresonant femtosecond pump–probe technique capable of measuring isotropic contributions to the transient birefringence of molecular ...

Illustration of a Raman-suppressed, X-cut thin film lithium niobate racetrack microresonator used for microcomb generation. Harvard researchers have demonstrated a special type of optical frequency ...
