By studying the deformed Fibonacci quasi-periodic structure, a broad omnidirectional reflection band covering all telecommunication bands is obtained. Deformation was introduced by applying a power law, so that the coordinates y of the deformed object were determined through the coordinates x of the non-deformed structure in accordance with the following rule: y = x<sup>1+k</sup>. Here k is the coefficient defining the deformation degree. From the numerical results performed by the transfer matrix method, it is found that the reflection band of the deformed 15th generation Fibonacci sequence structure covered all optical telecommunication bands.
