Sulfonamides are a class of synthetic broad spectrum antimicrobial drugs widely used in animal farms and human medicine. Sulfamethoxazole (SMX) is the most prevalent sulfonamide and has been detected in different aquatic environments in concentrations as high as 49.7 µg L-1 [1]. The scientific community and health organizations are increasingly concerned due to the potential toxicity to...

Tailoring the excitation of higher order modes (HOM) is of great importance across several applications within the photonics field, including optofluidics sensing, nonlinear phenomena generation, imaging, and in fiber communication systems. Nevertheless, effectively exciting specific HOM still remains a challenge.
Currently, HOM can be achieved resorting to certain optical devices such as...

124. Development of a quality control and calibration instrument for Rangefinders/LiDARs

Contributed Talk (20 minutes)

A proof-of-concept test bench to assess the quality and operation of rangefinders and LiDARs in a compact setup with a footprint small enough to sit on a usual optical table. In particular, the development subsystem includes an apparatus capable of measuring the maximum range of the rangefinder type of instrument. The range measurement will be implemented by mimicking a real backscattering...

This presentation summarizes the advances made in the first two years of my PhD fellowship program. Significant progress has been achieved in the area of laser-writing of nitrogen-vacancy (NV) centers, characterization of fluorescence microscopy and developing of ODMR systems and protocols for optimized sensitivity.
Advancements were made in the laser writing of NV center ensembles in...
