Latest Patents

One of his latest inventions involves multi-wavelength lasers. In this invention, an optical gain element is utilized where a fraction of the optical output signal is passed through a periodic filter and fed back to the gain medium. This configuration forms a multi-wavelength ring laser. The optical gain element provides the gain medium for the laser, while the filter ensures that the laser operates on predetermined wavelengths. The periodic filter can be an asymmetric Mach-Zehnder Interferometer (MZI), which is known for its almost sinusoidal wavelength response. The channel spacing can be controlled by adjusting the length difference of the arms of the asymmetric MZI.

Another notable patent is related to Mach-Zehnder interferometer (MZI) filter devices. This method involves creating an asymmetric Mach-Zehnder Interferometer by adjusting the lengths of the arms of two Michelson Interferometers (MI) to achieve the desired wavelength response. The two MIs are then combined to provide the MZI, resulting in an asymmetric MZI that comprises two asymmetric MIs optically connected back-to-back.
