摘要： An optical spectrum analyzer is implemented with a detector combined with a tunable filter mounted on a stage capable of 360-degree rotation at a constant velocity. Because of the constant rate of angular change, different portions of the input spectrum are detected at each increment of time as a function of filter position, which can be easily measured with an encoder for synchronization purposes. The unidirectional motion of the mirror permits operation at very high speeds with great mechanical reliability. The same improvements may be obtained using a diffraction grating or a prism, in which case the detector or an intervening mirror may be rotated instead of the grating or prism.

摘要： A conventional interference tunable filter is combined with a pair of shaping prisms to enlarge the circular input beam in the direction orthogonal to the direction of beam propagation and to the axis of rotation of the tunable filter. The degree of expansion is tailored to minimize the walk-off losses produced by successive reflections in the cavity of the tunable filter. By appropriately sizing the enlargement, the substantially elliptical beam produced by the shaping prisms encompasses sufficient reflected beams after passing through the tunable filter to produce substantially the same filter output that in a conventional filter would require a materially larger input beam. The input beam is preferably first converted to two parallel beams of the same polarization state. Both beams are then expanded by the prisms and processed by the tunable filter.

摘要： A four-fiber collimator is coupled to the optics of a single interleaver to produce the functionality of two co-packaged interleavers. Two fibers of the collimator are coupled to the core optics of a single interleaver to produce two pairs of output beams. The other two fibers of the collimators are coupled to receive the reflection output beams. The geometry of the optical fibers in the bundle is controlled to produce interleaver outputs with no offset. In another embodiment two fibers of the four-fiber collimator are coupled as inputs to and the other two fibers as outputs from a Fabry-Perot etalon. The geometry of the fibers and the focal length of the collimator are controlled to produce two outputs with peaks offset by a predetermined amount.

摘要： A plane-parallel optical window is the spacer of single-cavity filters in the stack used for DWDM applications. Highly reflective quarter-wave stacks are deposited on each side of the optical window and the single-cavity structure so obtained is diced to produce a plurality of filters. Each single-cavity filter so fabricated from the optical window has the same transmission wavelength and is therefore readily stackable for DWDM applications. Alternatively, an optical window with a thickness equal to one half that required for the spacer of a single-cavity filter is coated on a single side. The window is then divided in multiple identical components that can be combined in pairs by placing them in optical contact so as to form individual single-cavity filters with the same transmission-peak wavelength. The transmission peak of the filter can be fine tuned by controlling the temperature of the solid spacer material.

摘要： An interferometer includes a means for splitting, at a splitting location, an input light beam into a first beam and a second beam; and means for recombining, at a recombination location, the first beam and the second beam. The interferometer is designed such that the first beam will travel a first optical path length (OPL) from the splitting location to the recombination location, and the second beam will travel a second OPL from the splitting location to the recombination location and such that when the input light beam has bean modulated at a data rate comprising a time interval, then the difference in optical path lengths between the first OPL and the second OPL is about equal to the time interval multiplied by the speed of light.
