US Classification:

600562, 600182, 606 15

Abstract:

The present invention relates to an apparatus for producing optical pulses of a desired wavelength. The apparatus includes an optical pulse source operable to generate input optical pulses at a first wavelength. The apparatus further includes a higher order mode (HOM) fiber module operable to receive the input optical pulses at the first wavelength, and thereafter to produce output optical pulses at the desired wavelength by soliton self-frequency shift (SSFS). The present invention also relates to a method of producing optical pulses having a desired wavelength. This method includes generating input optical pulses using an optical pulse source, where the input optical pulses have a first wavelength and a first spatial mode. The input optical pulses are delivered into an HOM fiber module to alter the wavelength of the input optical pulses from the first wavelength to a desired wavelength by soliton self-frequency shift (SSFS) within the HOM fiber module, thereby producing output optical pulses having the desired wavelength.

Abstract:

A system for designing a photonics system, comprising a topology optimization module and a component parameter optimization module; wherein the topology optimization module searches candidate photonics systems through photonics combinations of component; and the component parameter optimization module searches for component parameters of the candidate photonics systems to simulate successive candidate photonics systems in a desired degree-of-freedom according to a target characteristic of the photonics system. The method comprises searching through different photonics combinations of components and component parameters and selecting candidate photonics systems, and searching component parameters of the candidate photonics systems in a desired degree-of-freedom according to a target characteristic of the photonics system.
