Methods for engineering few-cycle mode-locked lasers (PDF)
My PhD thesis, covering several computational and experimental methods I developed to engineer lasers producing ultra short pulses.

Two-dimensional spectral shearing interferometry (2DSI) (PDF)
Need to measure the waveform of an optical pulse lasting a few femtoseconds? This might help.

Modelocked Laser Steady-state Pulse Solver (PDF)
My SM thesis, covering an algorithm for solving directly for the steady state pulse of a nonlinear cavity with relatively weak nonlinearity, such as a solid-state femtosecond laser. The solution is typically found at least 10 times faster than with standard simulations, assuming a reasonable starting guess. Here is a short summary paper.

Phase Distortion Energy (PDF)
An alternative concept to dispersion, phase distortion energy is a better figure of merit to optimize for the performance of an optical system in many situations.

Ultrafast Optics Toolbox
MATLAB/C code for the fast optimization and analysis of dispersion from dielectric mirrors. Used for designing components for ultrafast optical systems and optical communications.

Diffraction theory illustration
A short visual illustration of the various diffraction theories,
intended for people already familiar with linear systems.

Tilt-Shift Aerial Photography of Boston
Images scaled for use as desktop backgrounds,
much of it aerial drone photography of Boston and New England.
