Latest Patents

One of her latest patents focuses on optical fibre-based devices that utilize the Raman effect. This invention comprises a first optical source that provides light at a first wavelength, and a holey optical fibre that receives this light. The device can operate as an amplifier or a laser, depending on the optical feedback provided. For optical gain, the second wavelength is longer than the first, while for optical loss, the second wavelength is shorter. The fibre can be made from pure silica or other materials to enhance its properties.

Another significant patent involves optical code generation and detection. This invention features optical code division multiple access (OCDMA) coder:decoder gratings. The modulated refractive index profile incorporates changes in polarity between OCDMA chips through discrete phase shifts. This allows for bipolar coding via phase modulation, achieving higher data rates and longer code sequences than previously demonstrated.
