SfeirLab Software for Research

Data Analysis and Visualization Software

Prof. Sfeir authors and maintains codes for the analysis of time-resolved spectroscopy data, primarily for the Igor Pro software package.

Visualization and Analysis of Broadband Transient Absorption Data

https://www.wavemetrics.com/project/TADataAnalysis

This package includes a set of functions for processing and graphing wavelength and time-resolved absorption data. This code was designed to process data created by the Helios Femtosecond Transient Absorption spectrometer produced by Ultrafast Systems, LLC. However, it will work with any data with a similar format.

PicoHarp File Access for Igor Pro

https://www.wavemetrics.com/project/ReadPicoHarpData

This procedure is based on the File Access Demo in Matlab script written by Peter Kapusta, PicoQuant GmbH, September 2006.
It was ported to IGOR Pro so that the binary data files (*.phd) created by the PicoHarp 300 time correlated single photon counting module can be directly read and analyzed.

Radio Frequency & Millimeter Wave Core Facility

The Radio Frequency and Millimeter-wave Core is a shared-user facility. The core includes fabrication and measurement units.

Electronics Fabrication Facility

The fabrication unit offers a complete in-house PCB prototyping (multilayer rigid and flex) through high-end laser and mechanical equipment. Furthermore, the fabrication unit provides a complete component placement and rework cycle including high-end fully- and semi-automatic rework stations enabling desoldering, soldering, and residual solder removal of SMDs and BGAs as small as 01005.

Measurement Facility

The measurement facility offers an anechoic test chamber capable of measuring electromagnetic radiation, high-end spherical nearfield measurement system, planar nearfield scanner (all in frequencies ranging from 1-110 GHz), and high-end PNAs and other required equipment for a fully in-house measurement cycle.
