Run the scripts in the following order on Comsol livelink with Matlab:

create_model.m: create the strip geometry comsol model for mechanics (geometry, material, physics, mesh); create and solve the comsol model for optics (optical cavity is located in the bulk) (Note: simulation time and memory usage is very long; recommended to use a cluster)
solve_model.m: solve the comsol mechanics model and evaulate the optomechanical coupling. Running this script will require a large amount of memory (greater than 500 GB), hence one needs to use a high memory cluster to run this script.

The outputs of both the scripts are stored in ../plot_spectrum/datasets.
