Original method for measurement of optical mode fields.
We report on a new method for measurement of mode spot sizes of fibers or waveguides (Ti-diffused or proton-exchanged waveguides on LiNbO(3)) that uses neither camera nor optics and works at any wavelength with a 1-μm resolution. The measurements are in good agreement with a finite element simulation.
