Abstract
An optical signal processing method and a device which can serve as a signal multiplexer or demultiplexer can be tuned in discrete increments. This device has a movable filter assembly having a number of filters, with each filter having a surface which reflects a particular wavelength of light and passes other wavelengths of light. This defines two wavelength-dependent signal paths. Light reflecting from a reflective surface of the filter passes along one signal path which includes an input waveguide and a first output waveguide. Light transmitted through the filter travels along another signal path which includes the input waveguide and a second output waveguide. The filter can be contained in a trench separating the input and second output waveguides, and can be moved in the trench to alter the optical properties of the two signal paths.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
