We show that optical Bloch oscillations can emerge in waveguide arrays with Linearly varying propagation constants. The existence of localized modes (Wannier-Stark. states) with equidistant wave-number spacing (Wannier-Stark ladder) that do not undergo diffraction is analytically proved. The evolution of arbitrary initial excitations is described, and potential applications are suggested. (C) 1998 Optical Society of America.
