Latest Patents

Ferrieres holds a patent for "Vertical external cavity surface emitting laser devices allowing high coherence, high power and large tunability." This laser device is designed to generate an optical wave at a specific laser frequency. It includes a semiconductor element with a gain region containing quantum wells, positioned between a first mirror and an exit region that defines an optical microcavity. Additionally, a second mirror is arranged to form an external optical cavity with the first mirror, which includes the gain region. The device is equipped with a pump that energizes the gain region to produce the optical wave. The configuration allows for a spectral ratio between the Half Width Half Maximum (HWHM) spectral bandwidth of the modal gain and the free spectral range of the external cavity to be maintained within a range of 2 to 50.
