Latest Patents

Dion's latest patents include a "Tunable laser with multiple in-line sections including sampled gratings." This invention features a semiconductor laser body with several in-line laser sections that can be independently driven to generate laser light at different wavelengths. The sampled gratings in these sections have the same grating period but different sampling periods, allowing for the tuning of light generated in response to temperature changes. This design simplifies the fabrication of the tunable laser.

Another significant patent is the "Two-section semiconductor laser with modulation-independent grating section to reduce chirp." This invention consists of a gain section and a modulation-independent grating section, which helps to reduce chirp. The grating section includes a diffraction grating that reflects light and forms a laser cavity with the gain section. This configuration allows for direct modulation of the semiconductor laser without significantly affecting the index of refraction in the diffraction grating, thus minimizing chirp.
