Broadband mid-infrared coherent light source from fiber-laser-pumped difference frequency generators based on cascaded crystals

2020 Conference on Lasers and Electro-Optics Pacific Rim (CLEO-PR), 2020
We experimentally obtained mid-infrared sources having instantaneous-bandwidth covering $2.8- 3.9 \mu \mathrm{m}$ from DFGs based on two cascaded PPLN crystals.

Mid-infrared homodyne balanced detector for quantum light characterization

, 2021
We present the characterization of a novel balanced homodyne detector operating in the mid-infrared. The challenging task of revealing non-classicality in mid-infrared light, e.~g. in quantum cascade lasers emission, requires a high-performance detection

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Toward 100‐Watt‐Level Mid‐Infrared Supercontinuum Light Generation

Advanced Photonics Research
The applications of mid‐infrared supercontinuum (SC) light sources are currently being extended to various fields. However, the difficulties (including thermal limitation, optical damage, and chemical stability) in increasing their output power to 100 ...

The femtochemistry of the ferrioxalate actinometer [PDF]

EPJ Web of Conferences, 2019
The ferrioxalate actinometer is widely used as an analytical standard to determine the photon flux of light sources in photochemical reactors. Yet, the underlying mechanistic functioning of the actinometer at the molecular level is entirely unknown. Here,

FDTD modelling of mid infrared disk lasers [PDF]

, 2007
This paper presents 2D FDTD modelling of a disk resonator that could be used as a disk laser. Results are shown for mode spacing and good agreement with a simple Whispering Gallery Mode model is observed.

Wearable Smart Patches on Sustainable Chitosan With Reversible Microbial Growth‐Inhibitory Properties

Advanced Functional Materials, EarlyView.
ABSTRACT Chitosan, a polysaccharide upcycled from biowaste, has long promised sustainable, biocompatible, and antimicrobial films and devices, an appeal reinforced by its recent regulatory recognition, with several chitosan‐based antibacterial dressings gaining clearance through the Food and Drug Administration's 510(k) pathway.

Mid-infrared integrated photonics on silicon: a perspective

Nanophotonics, 2017
The emergence of silicon photonics over the past two decades has established silicon as a preferred substrate platform for photonic integration. While most silicon-based photonic components have so far been realized in the near-infrared (near-IR ...

Ground‐State Charge‐Transfer Doping in Donor–Acceptor Semiconducting Polymers

Advanced Functional Materials, EarlyView.
This work demonstrates controlled ground‐state charge‐transfer complex formation (GS‐CTC) and doping in a series of diketopyrrolopyrrole‐based donor–acceptor semiconducting polymers paired with a π‐conjugated penta‐t‐butylpentacyanopentabenzo[25]annulene “cyanostar” macrocycle. Complementary experimental techniques show how subtle molecular, electronic,
