| 20080267230 | Device For Wide Range Continuous Wavelength Sweeping on a Set of Tunable Laser Sources - A device for wide range continuous wavelength sweeping on a set of tunable laser sources over a predetermined global wavelength range, the device working with at least one functional pair of cooperating tunable lasers, each laser of the cooperating pair emitting over a sub range of the global wavelength range, the sub ranges of a functional pair partly overlapping each other in an overlapping wavelength zone, all the sub ranges being included within the global wavelength range and the sweeping of the output laser signal being done by the selection and tuning of one of the lasers of one of the functional pairs at a time. The device includes for a functional pair of cooperating tunable lasers an optical switch and an heterodyne optical detector. | 10-30-2008 |
