Patent number: 6870629Abstract: The invention allows for the accurate, real-time readout of the optical frequency of a swept-wavelength laser device by counting the number of fringes of a calibrated etalon that occur as the laser is swept. The distinguishing feature of the present invention is that the etalon fringe signal is phase-locked to a slave signal of a higher multiple frequency. The higher frequency of the slave signal divides the frequency interval of the etalon fringe spacing by the additional frequency multiple. The slave signal therefore generates a scale for optical frequency that is of higher resolution than possible with the etalon alone. The phase-lock also insures that the slave signal tracks monotonic scans of the optical frequency regardless of scan profile. The invention also allows for the precise, real-time control of the optical frequency of a laser during the sweep of the laser.Type: GrantFiled: October 29, 2002Date of Patent: March 22, 2005Assignee: Precision Photonics CorporationInventors: Kurt R.

Publication number: 20030035120Abstract: The invention describes devices and methods for determining the wavelength of coherent optical radiation such as is emitted from a laser source. The apparatus is monolithic with no moving parts and consists of optical components that generate signal periodic in the optical frequency of the coherent radiation detected by the component. Each optical component generates a signal with a different period. Differences between the periods of the signals generated by the optical frequency-dependent optical components provides a means of measuring optical wavelengths over a range far exceeding the free spectral range limitations of conventional interferometers. The method of the present invention allows for measurement of optical frequency with an uncertainty of much less than the period of the optical frequency-dependent optical components forming the apparatus.Type: ApplicationFiled: April 10, 2002Publication date: February 20, 2003Inventors: Christopher J. Myatt, Kurt R. Vogel, Tim Dinneen, Jason R. Ensher
