Optical Pulse Delay Generator

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention relates to an optical pulse delay generator, which is a device that delays optical pulses in a controlled way. It does so by using two dispersive optical converters to separate, modulate, and then recombine the spectral components of a pulse, effectively delaying the output pulse. The approach uses waveguide resonator rings with different optical lengths to achieve precise and configurable delays.

Patent Abstract

An optical pulse delay generator is provided. The optical pulse delay generator includes a first optical converter which is dispersive and separates the spectral components of the incoming optical pulse in a time domain. The first optical converter generating a converted optical signal. The optical pulse delay generator also includes a modulator to modulate the converted optical signal and to generate a modulated optical signal and a second optical converter connected to the modulator. The second optical converter being dispersive for overlaying the previously separated spectral components in the time domain and generating the delayed optical output pulse. The dispersion imposed by the second optical converter has the same amount of dispersion, but the opposite sign, as the first optical converter. At least one of the first and second optical converter includes at least two waveguide resonator rings which differ in their optical length.
