Abstract: A method and system is disclosed for increasing the holographic storage capacity of a holographic recording medium using an irradiance-tailoring (e.g., optical) element by changing the irradiance profile of the modulated object beam (e.g., by imparting motion to an irradiance-tailoring element and/or the holographic recording medium and/or by reconfiguring (e.g., periodically) the phase profile of a stationary irradiance-tailoring (e.g., optical) element) to minimize the effects of fixed-pattern noise buildup from occurring in the holographic recording medium.

Abstract: Retroreflecting elements adapted for use in one-to-M wavelength routing elements are provided. Each retroreflecting element is configured to retroreflect an optical ray that is orthogonal to a reference plane. A first reflective surface, such as may be provided by a mirror, is inclined with respect to the reference plane and is disposed to encounter the optical ray. The first reflective surface is also configured for rotation about an axis to multiple positions. A second reflective surface, such as may also be provided by a mirror, is inclined with respect to the first reflective surface. In at least one of the positions, the optical ray also encounters the second reflective surface.
