Updated:

This spring I built an open-faced shed in our yard, primarily as a convenient shelter to store out bikes.

The one true triathlon distance

10 minute read

Updated:

I have created a web-scraping tool to pull athlete result data from Ironman triathlon events. Using some of this data I’d like to do some simple analysis on the relative distances and finishing times of the three disciplines in triathlon: swim, bike run.

Flask deployment on Heroku

Updated:

You’ve developed a Flask app locally. It runs, and you are at the point that you’d like to publish to the web. Or get the ball rolling, at least. It is time for deployment.

Theory and demonstration of fluorescence-based refractometric sensing in glass micro-capillaries with a silicon nanocrystal-embedded film

Published in 13th International Conference on Transparent Optical Networks, 2011

We demonstrate fluorescence-based refractometric sensing using whispering gallery modes in glass micro-capillaries with a quantum-dot film.

Synthesis and operation of fluorescent-core microcavities for refractometric sensing

Published in Journal of Visualized Experiments​, 2013

Fluorescent-core microcavity sensors employ a high-index quantum-dot coating in the channel of silica microcapillaries. Changes in the refractive index of fluids pumped into the capillary channel cause shifts in the microcavity fluorescence spectrum that can be used to analyze the channel medium.

Evaluation of form birefringence in chiral nematic mesoporous materials

Published in Journal of Materials Chemistry C, 2014

We present a detailed investigation into the form birefringence of chiral nematic mesoporous materials templated by the self-assembly of cellulose nanocrystals as the potential basis to detect changes in refractive index in an optical sensor using circular dichroism (CD) spectroscopy.

Versatile, high-power femtosecond laser source at 1um

Published in CLEO, 2016

We describe a stable, compact, femtosecond laser system based on Yb-doped gain media. Capable of delivering sub-300 fs pulses with mJ energy, the system is an attractive alternative to traditional Ti:sapphire systems.

ICTON 2011 - Refractometric Sensing with FCMs

Updated:

We demonstrate fluorescence-based refractometric sensing using whispering gallery modes in glass micro-capillaries with a quantum-dot film. A theoretical analysis of the device is also presented. The device exploits a solution-based method to coat the interior channel of a glass capillary with a high-quality film consisting of fluorescent silicon nanocrystals. This film supports the whispering gallery modes that propagate largely within the nanocrystal film. The inner tail of the mode samples the capillary channel; this forms the basis for a refractometric sensing method for fluids pumped through the channel. A refractometric sensitivity of 9.8 nm/RIU was observed in this structure, offering a new, fluorescence-based alternative to liquid core ring resonator structures.
