The Bloch oscillations in the zigzag array of the optical waveguides areconsidered. The multiple scattering formalism (MSF) is used for the numericalsimulation of the optical beam which propagates within the array. The effect ofthe second-order coupling which depends on the geometrical parameters of thearray is investigated. The results obtained within the MSF are compared withthe calculation based on the phenomenological coupling modes model. Thecalculations are performed for the waveguides fabricated in alkaline earthboro-aluminosilicate glass sample, which are the most promising for the C-band(1530-1565 nm).
