This is the beginning of the fourth week of the REU program, and I believe it is time for me to pick a topic for the summer and begin to narrow my focus. I think my focus is narrowing into non-linear optics. There is the LiNbO3 crystal in the lab. That crystal is very interesting.
I think what I want to experiment on with this crystal is frequency doubling. In general, the final goal is to successfully achieve frequency doubling, using a non-linear medium. I don’t really care what sort of non-linear medium I use.
The second interest, but the one I think is less applicable is the optical logic gate.
