Latest Patents

One of Michael Raab's latest inventions is the Brillouin ring laser gyro. This innovative device features a fiber ring resonator that exhibits a sequence of resonance frequencies. The neighboring resonance frequencies differ by a free spectral range, and two pump laser waves of opposite directions are generated. The frequency difference of these pump laser waves is an integral multiple of the free spectral range of the fiber ring resonator. The invention addresses frequency fluctuations that occur with two-color ring laser gyros by providing means for damping feedback components of the laser light originating outside the fiber ring resonator.

Another notable patent is the optical ring resonator sensor. This sensor is designed to measure a physical quantity that causes a non-reciprocal effect, such as the Sagnac effect, in an optical ring resonator. The Sagnac effect results in a difference in clockwise and counter-clockwise optical path lengths in the ring resonator, which is proportional to the physical quantity being measured, such as rotation rate. The sensor utilizes a semiconductor laser coupled to the ring resonator, generating both clockwise and counter-clockwise beams. A detector device responds to the difference in these light beams, generating a signal indicative of the measured physical quantity.
