In order to study guiding and far-field radiation characteristics of micro/nano optical fibers,the relation between core diameters and the mode field,z-direction Poynting vector,effective mode area and far-field intensity was simulated.Then experimental demonstration was carried out by means of tapered fibers.The results showed that the micro/nano fibers might have a large mode area evanescent field larger than 1O00μm2 for an appropriate design.Experimental results of tapered fibers verify that the micro/nano optical fiber can effectively guide the field and radiate it out.
