Abstract

Bending losses of nanofibers or nanowires with circular $\mathrm{90}\mathrm{°}$ bends are simulated using a three- dimensional finite-difference time-domain (3D-FDTD) method. Dependences of bending losses on wavelength and polarization of guided light are investigated, as well as the diameters, refractive indices, and bending radii of nanowires. The acceptable bending losses ($\sim 1\mathrm{dB}/90°$) predicted in glass, polymer, and semiconductor nanowires with bending radii down to micrometer level may offer valuable references for assembling highly compact photonic integrated circuits or devices with optical nanowires.
