Abstract: The ability to address sub-picosecond events of weak optical signals is essential for progress in quantum science, nonlinear optics, and ultrafast spectroscopy. While up-conversion and optical Kerr gating (OKG) offer femtosecond resolution, they are generally limited to ensemble measurements, making ultrafast detection in nano-optics challenging. OKG, with its broadband response and high throughput without phase-matching, is especially promising when used at high repetition rates under focused illumination.
Here, we demonstrate an ultrafast detection scheme using the third-order nonlinearity of graphene and thin graphite films, operating at 1 GHz with sub-nanojoule pulses and achieving 141 fs temporal resolution. Their exceptionally large nonlinear refractive index, orders of magnitude higher than conventional Kerr media, enhances detection efficiency at smaller thicknesses, enables sub-picosecond response, and supports broadband operation. Their atomic-scale thickness minimizes dispersion and simplifies integration with microscopy platforms, optical fibers, and nanophotonic circuits, making them a compact, practical material platform for nano-optical and on-chip ultrafast Kerr gating.

"We don’t really think about our future – we remember it",
said Dr Hal Hershfield, who studies how humans think about time and how that influences our emotions and behaviors.
When we daydream or envision ourselves at a later point, we essentially create a memory.
We then use these memories to construct our ideas about the future.
This process is called “episodic future thinking”;
it supports our decision-making, emotional regulation and ability to p…

GCVE BCP-05 drafting - Best practices for the "container" format - modified CVE Record Format
Thanks @claudex . This is an excellent point and would also improve the ability to parse GCVE records reliably. Below is a proposal for a record_type field that would serve as a key within each GCVE record. Feel free to comment. @cedric I incorporated the idea concerning the sync of the comment (not sure if the most efficient way). Proposed update to BCP-05 (following the online workshop of 6th December in Belgium) The record_type field defines the semantic category of the content submitted by…
