Latest Patents

One of Couillaud's key patents is titled "Method of and apparatus for measuring optical frequency variations." This invention discloses a method and apparatus that utilize linearly-polarized incident light generated by a tunable laser. The light is delivered to a passive resonant cavity that incorporates a linear polarizer, such as a Brewster plate. The reflected light acquires a frequency-dependent elliptical polarization, which can be detected by a simple polarization analyzer. This setup provides a signal that correlates with the frequency variation of the laser. Such a signal can be utilized as a feedback error signal to stabilize the laser frequency or to adjust the cavity resonance. If the cavity is tunable, tuning it will provide a precision method for tuning the laser itself. Couillaud holds 1 patent for this innovative technology.
