Abstract:
A wavelength reference device (110) for tuning a tunable Fabry-Perot filter and/or a tunable VCSEL (105) to a desired frequency, where the device uses a Fizeau interferometer (125) and a position sensitive detector (130), with the position sensitive detector (130) being used to measure the location of the maximum reflected power from the interferometer (125), whereby to determine the wavelength of laser radiation for tuning the device (110).
Abstract:
An etalon (5) comprising a first plate (10) and a second plate (10) positioned in parallel to one another, separated by a block spacer (15) extending the distance between the first plate and the second plate. The block spacer having a perimeter (30) defining a chamber (20) extending the distance between the first plate and the second plate.
Abstract:
Apparatus (5) is disclosed for aligning optical components (10). The apparatus (5) comprises a light source (15) providing an emission, an optical element (20) for receiving the emission from the light source (15), and at least one of the light source (15) and the optical element (20) being mounted to a gimbal mount (25). Adjustment of the light source (15) and/or the optical element (20) mounted to the gimbal mount (25) adjusts the angle of incidence of the emission from the light source (15) on the optical element (20). This adjustment in turn aligns the optical components (10). A method is disclosed for aligning optical components (10). The method comprises generating an emission from a light source (15), adjusting a gimbal mount (25) on at least one of the light source (15) and an optical element (20), wherein the angle of incidence of the emission from the light source (15) is adjusted on the optical element (20), and fixing in place the position of the gimbal mount (25) on the light source (15) and/or the optical element (20).
Abstract:
An optical fiber wavelength reference device (110) for tuning a tunable Fabry-Perot filter (105) and/or a tunable VCSEL (105) to a desired frequency, where the device uses a fiber etalon (120) to generate a pattern of reference frequencies against which the device is tuned. In addition, the device uses a detector (125) to monitor the output of the Fiber Etalon (120). The ouput of the detector (125) is inputed to a controller (115) used to control the VCSEL (105) or tunable Fabrey-Perot filter (105).
