Patent number: 9246312Abstract: A Fabry-Pérot tuneable filter device is described with reflecting elements separated by an optical path length to form an optical resonator cavity. A first actuator means is directly or indirectly coupled with a first reflecting element. And the first actuator means is configured to modulate the optical path length between first and second reflecting elements by a modulation amplitude to thereby sweep the optical resonator cavity through a band of optical resonance frequencies with a sweep frequency of 70 kHz or more. And the mechanical coupling between selected elements of the arrangement is sufficiently low such that when operated at the sweep frequency, the selected elements act as a system of coupled oscillating elements. In addition or alternatively, the first actuator means is directly or indirectly coupled with the first reflecting element so as to substantially drive the first reflecting element only.Type: GrantFiled: September 4, 2014Date of Patent: January 26, 2016Assignee: Ludwig-Maximilians-Universität MünchenInventors: Robert Huber, Wolfgang Wieser, Thomas Klein, Christoph Eigenwillig, Benjamin Biedermann, Dieter Muellner, Michael Eder

Patent number: 8810901Abstract: In at least one embodiment of the wavelength-tunable light source (1), it comprises an output source (2), which is capable in operation of generating electromagnetic radiation (R). Furthermore, the light source (1) has a wavelength-selective first filter element (5), which is situated downstream from the output source (2). Moreover, the light source (1) contains a first amplifier medium (3), which is situated downstream from the first filter element (5) and is capable of at least partial amplification of the radiation (R) emitted by the output source (2). The light source (1) further comprises at least one wavelength-selective second filter element (6), which is situated downstream from the first amplifier medium (3), the second filter element (6) having an optical spacing (L) to the first filter element (5). The first filter element (5) and the at least one second filter element (6) are tunable via a control unit (11), which the light source (1) has.Type: GrantFiled: September 3, 2009Date of Patent: August 19, 2014Assignee: Lightlab Imaging, Inc.Inventors: Robert Alexander Huber, Christoph Eigenwillig, Benjamin Biedermann
