Latest Patents

Helene holds a patent for a tunable laser device. This device comprises a multi-section distributed feedback (DFB) laser that includes a first Bragg section with a waveguide and a Bragg grating, a second Bragg section also featuring a waveguide and a Bragg grating, and a phase section located longitudinally between the two Bragg sections. The phase section is made of a passive material, and each Bragg section has a first longitudinal end that joins the phase section and a second longitudinal end that is opposed to the phase section. Notably, the Bragg grating of at least one Bragg section has a grating coupling coefficient that decreases from the first longitudinal end to the second longitudinal end of that section. This innovative design enhances the functionality and efficiency of tunable lasers.
