Latest Patents

One of Walko's latest patents is titled "Temperature-tuned ultrafast X-ray shutter using optics-on-a-chip." This invention addresses the limitations of traditional modulation systems, which often struggle to perform synchronous modulation for high-energy radiation systems. The method described involves an oscillatory diffractive element that can be oscillated over a range of angles. A radiation source provides radiation to this element, while an electrical signal is used to modulate the radiation through oscillation. A temperature controller is also integrated to fine-tune the oscillatory motion of the diffractive element.

Another significant patent is for "Ultrafast photonic micro-systems." This microelectromechanical device features a diffractive element suspended over a channel, designed to receive and manipulate optical beams based on its orientation. The device includes at least one torsional actuator that allows for selective adjustment of the diffractive element's orientation, optimizing its interaction with the optical beam.
