Latest Patents

Schlager holds a patent for a wavelength division multiplex type mode-lock laser device. This device is designed to simultaneously generate high-speed optical pulse trains for multiple wavelengths. It modifies either a ring resonator type mode-lock laser device or a Fabry-Perot type mode-lock laser device to create an optical path difference. This structure provides different refractive indices for polarization directions that are perpendicular to one another. The innovation enables the configuration of a resonator that corresponds to the optical path lengths formed according to the refractive indices, along with hetero-wavelength optical path equalizing means.
