Sooooooo.... What'cha doing?
In the lab we have three main processes that we do, the first and most obvious is the physical testing of micro discs, and resonance.
The second is two dimensional computer modeling using the Lumerical FDTD simulation software.
Then the third and final process is that of three dimensional modeling using the same software.
Physical movement of the fiber next to resonators is tricky business. because of equipment constantans you never know how far above a resonator you are, nor can you ever clearly see edges of objects.
The first constraint is because if you ever touch the tapered fiber to a surface then it will stick, and must be manually removed, which resets the initial height that one computer controlled, and delicately, lowers the fiber from to be near the resonator.
The latter constraint is due to the small size that we are working on, and the fact that most objects are made out of glass, thus twisting glass naturally.
These constraints can make testing frustrating, and delicate task, at the same time, because success is so hard, when archived, there is jubilation.
2D and
3D modeling are similar in purpose, to be able to model how light reacts in a perfect (lack of imperfections in disk & fiber quality) and easy to control world (they can be positioned anywhere wanted relative to each other).
The advantages for one over the other are that 2D takes about 5% of the time to model as a 3D model does.
3D modeling though offers the ability to look at the transverse electrical mode, and for the model to reflect a the more accurate physical setup.
After we have generated data in either our physical setup, or on the computer, then we like to analysis it in excel, forming graphs for easy viewing, and also calculating resolution values.
