My Projects
We all know that light emitted by a laser is of specific color. In fact, it has a very defined shade of that color. Loosely speaking, that's what makes a laser different from a flashlight.
Physicists like to quantify the way we perceive colors and shades by describing the light as electromagnetic fields of specific frequency. In an ideal world, a laser field will have a single frequency tone. Of course, it is not ideal - however beautiful the world is, it is also fundamentally noisy. Unavoidable noise in the laser's cavity causes the single frequency tone to broaden. Sometimes it causes that frequency to drift over time, effectively changing the color of the laser's light field.
My research over the last few years was focused on the control and manipulation of the frequency and phase of a laser field. The projects described in this website includes phase locking of several different lasers, precise control over laser frequency chirps, and the fabrication of a new type of semiconductor laser with superior noise performance.
