Abstract
Simultaneous two-dimensional nanometric-scale position monitoring can be achieved in a simple interferometric setup by real-time probing a hexagonal photonic crystal glass substrate. The minimum detectable translational movement is determined by the period of photonic crystal array, and can be as high as 8 nm in the present work.
