Spectroscopic-Detection Biochips Based on Photonic Waveguides

Using POEMS to design waveguides, coupling structures, and optical/chemical interaction regions; consulting on microfabrication issues

Bootstrap Charge Sensitive Front End

This is for for a scanning surface potential measurement tool, used in contamination detection in semiconductors: 40 attocoulomb sensitivity in a 4 MHz bandwidth

SWIR Grating Spectrometer Proof of Concept

This was a prototype of a transcutaneous (through-the-skin) sensor for blood glucose and blood alcohol.

Blood Detector for Egg Grading

A bit of a departure from our usual fare: a low cost, high speed sensor for detecting blood spots in eggs using spectral differencing. I'm going to be doing the firmware as well as the optics and electronics, and this will be the first actual client work for our newly qualified PCB designer, Magdalen.

Plate Reader for Water Quality Assay

This is a research project with a small division of a very large manufacturer. It's a complete optical/electronic design to measure optical absorbance in a rapidly moving assay plate.
