摘要： An optical system such as an add and/or drop WDM multiplexer allows the wavelength fluctuation of an optical carrier to be tracked so that a corresponding fiber Bragg grating (FBG) can be responsively tuned. The preferred embodiment of the wavelength tracking system in an optical system such as an add and/or drop module includes a three-port optical circulator, three optical fibers, a series of tunable FBGs, a source of a broadband optical noise signal, an optical spectrum analyzer (OSA), and an FBG tuner. In operation, an LED generates modulated probe lightwaves that are inserted into a drop module. The LED lightwaves and the optical carriers propagating through the drop module are monitored by an OSA. The monitoring procedure determines the conditions, in terms of target wavelengths of the FBGs, and the stability or instability of the optical carriers. The FBGs are then tuned in response to the FBG and optical carrier information. In another embodiment, the wavelength of an optical carrier is tracked using a modulated tracking grating and an FBG is adjusted in response to the tracking information.

摘要： An apparatus for characterizing a short optical input pulse is provided. The apparatus has an optical disperser and an analyzer. The optical disperser disperses the input pulse temporally to an extent adequate for the analyzer to analyze. The analyzer analyzes the intensity and phase characteristics of the dispersed pulse which is used to obtain the intensity and phase characteristics of the input pulse. The characteristics of the input pulse are obtained by mathematically back-propagating the dispersed pulse through the disperser. Preferably, the analyzer has a discriminator that splits the dispersed pulse into two portions that travel along two paths of unequal length and then collimating the two portions to obtain optical interference. By analyzing the optical interference, the intensity and the phase of the dispersed pulse can be determined.

摘要： An apparatus for creating an optical noise of a predetermined bandwidth that uses an optical amplifier which amplifies optical noise components and produces unpolarized optical noise by spontaneous emission, a mirror to reflect the optical noise components back to the optical amplifier and a filter that filters out optical noise components outside the predetermined optical bandwidth. The filter is located so that optical noise components passed by the filter are amplified in the optical amplifier during an additional amplification. Optionally, a polarizer and Faraday rotator are used in the apparatus. The optical noise created in the optical amplifier is polarized in the polarizer after two amplifications, rotated in the Faraday rotator, then amplified two more times before leaving the apparatus.

摘要： A periodic grating structure is placed on a facing surface formed on an optical fiber so that the grating structure is within a portion of the evanescent field of an optical signal propagating through the optical fiber. The spatial periodicity of the grating structure is selected to be equal to one-half the propagation wavelength of the optical signal. The grating structure causes the optical signal to be reflected at an angle of 180 degress and thus to propagate in a reverse direction from its original direction of propagation.

摘要： A broadband tunable in-fiber filter includes a grating with divergent ridges which can be translated transversely of a side-polished optical fiber to vary the periodicity at an exposed evanescent field. The divergence is gradual so that at any given transverse position of the grating, the ridge interacting with the evanescent field are effectively parallel. The divergence is great enough so that a tuning-to-reflected bandwidth ratio of about 33:1 is demonstrated. The grating is fabricated in an amorphous silicon film on a fused quartz substrate. The film is coated with photoresist which is exposed to a holographic interference front. The substrate is tilted with respect to an interference front created by two spherically diverging beams to achieve the desired divergence. Subsequent processing, including etching are standard.

摘要： A fiber optic saturable absorber for processing optical signals comprises an optical fiber from which a portion of the cladding is removed to form a facing surface. A light-absorbing substance having non-linear light-absorbing characteristics is applied to the facing surface such that a portion of the optical signal energy is transferred from the fiber to the substance where it is absorbed. The device selectively attenuates the optical signal and noise, and can be used to reduce pulse waveform distortion caused by pulse broadening and by amplification of system noise.

摘要： Methods and apparatuses to provide wavelength locked WDM Passive Optical Networks (“PONs”) are described. A first transceiver transmits a set of optical signals in a first direction along a wavelength channel. A second transceiver transmits another set of optical signals along the same wavelength channel in another direction. The wavelength of the first transceiver is locked using an optical power of the optical signals of the second transceiver. The wavelength of the second transceiver is locked using the optical power of the optical signals of the first transceiver. A WDM MUX/De-MUX is coupled between the first transceiver and the second transceiver. An in-line gain element can be coupled to the WDM MUX/De-MUX to amplify the optical signals. The first transceiver and the second transceiver operate in a saturated gain condition.

摘要： Methods and apparatuses to provide an “Open access” service model using wavelength division multiplexing (“WDM”) passive optical networks (“PONs”) are described. A cross-connect is used to supply a first set of optical signals corresponding to a first service provider and a second set of optical signals corresponding to a second service provider to a WDM multiplexer/demultiplexer. The WDM multiplexer/de-multiplexer is used to multiplex and transmit the first set and the second set to a remote location. Another WDM multiplexer/de-multiplexer at the remote location is used to de-multiplex the first set and the second set. The first set may be supplied to a first user and the second set may be supplied to a second user. Transceivers coupled to the cross-connect may be used to generate the optical signals. For one embodiment, the transceivers include a wavelength-locked light source. For one embodiment, the transceivers are alike.
