Latest Patents

One of Lallier's latest patents is a compact optical source based on the frequency doubling of a laser. This invention is capable of emitting wavelengths, particularly in the blue spectrum, which are challenging for standard laser diodes to achieve. The design includes a laser or laser diode emitting at a specific wavelength, a non-linear medium where the phase matching condition is met, and a mirror that is transparent at one wavelength while reflective at another. By reinjecting certain wavelengths into the laser, the emission can be locked to achieve a high-powered optical source. Another significant patent is a frequency doubler that features an electrically controlled optical index. This device includes an optical index network that can be adjusted using continuous electrodes, allowing for electro-optical compensation for variations in the index between different polarization domains.
