Latest Patents
One of Driss Touahri's latest patents is titled "Elimination of optical ghosts in optical spectral analyzers through a scanning spectral filter." This invention involves a monochromator apparatus in a grating-based optical spectrum analyzer (OSA) that includes a diffraction grating, a reflector element, and a tunable spectral filter. The tunable spectral filter may consist of various types, such as a band-pass filter, low-pass filter, high-pass filter, or a linear variable filter. The spectral window of the filter is designed to move synchronously with the scanning spectral window of the OSA, effectively addressing the issue of optical ghost signals.
Another notable patent is for "Variable optical attenuator arrays." This invention features a variable optical attenuator (VOA) that includes an input collimator and an output collimator, both connected to fibers. A retroreflector receives a light beam from the input collimator and reflects it to the output collimator. The VOA incorporates attenuation elements that can be adjusted to set the desired attenuation level, utilizing components such as gradient index (GRIN) elements, polarizers, and neutral density filters.
