摘要： The invention relates to an optical coupling device that provides passive compensation for a shift in center wavelength due to a change in ambient temperature. A conventional solution is to mount one of the elements to be coupled on a pedestal or cantilevered arm, which has a coefficient of thermal expansion (CTE) different from a frame fixed relative to the other of the elements to be coupled. Unfortunately, these devices do not provide consistent results over long periods of time, due to uncontrolled movement of the outer free end of the cantilevered arm or pedestal. The present invention provides an expansion arm fixed on one end to a frame, a holder on the other end of the expansion arm, and a pair of flexible arms connecting the holder to the frame. This arrangement enables the expansion arm to freely expand in a first direction, while greatly restricting movement in any other direction. The present invention also relates to a optical coupling device that includes a expansion arm with an adjustable effective length. Furthermore, optical coupling devices are disclosed that include an expansion arm for moving a lens relative to one or more waveguides providing thermal compensation.

摘要： A tunable optical filter is configured to take point measurements at a few optical frequencies per frequency channel of a DWDM optical network. The measurement frequencies are shifted by pre-determined amounts relative to the optical frequency channel being characterized. Since the spectral shape of the tunable optical filter is known, the center optical frequency, the modulation bandwidth, and the total optical power of the channel can be obtained from as few as three optical measurements. The center optical frequency and the total optical power can be continuously monitored by providing a tunable filter stage coupled to an interleaver stage, and computing a ratio and a weighted sum the optical signals at the two outputs of the interleaver stage.

摘要： A tunable PLC optical filter having sequentially connected thermally tunable Mach-Zehnder (MZ) interferometers is described. The cascade of MZ interferometers, each having a free spectral ranges matching ITU frequency grid spacing, are tuned so as to have a common passband centered on the frequency of the signal being selected, while having at least one of the stopbands centered on any other ITU frequency. Any other optical channel that may be present at any other ITU frequency is suppressed as a result. Another MZ interferometer in series with the cascade of interferometers including an asymmetric or variable coupler, is tuned to have low transmission at the center frequency of the selected optical channel.
