Abstract
Over the last several years, the rapidly increasing traffic volume carried by telecommunication networks has been clearly observed as a result of the bandwidth-intensive applications such as Internet access, electronic commerce, multimedia applications, and distributed computing. Optical telecommunication systems employing optical fibers as the transmission medium have exhibited a superior performance/cost ratio for both long-haul and short-haul routes and the emerging dense wavelength division multiplexing (DWDM)/all-optical networks have shown some promising potentials. However there still exists a need to improve speed, capacity and connectivity of optical telecommunication networks, as the information system's subscriber growth increases unrestrained. The present invention provides a reconfigurable and scalable fiber optic switching for optical telecommunication networks by integrating MEMS actuators and PLCs for optical signal switching and routing. The integrated optic waveguide switches and optical cross-connect networks are particularly applicable for DWDM/all-optical networks due to its low cost, small crosstalk, reliable, compact, reconfigurable, modular, scalable, and wavelength/polarization insensitive characteristics. The integrated optic waveguide switch can be configured into a variety of all-optical network component such as Add/Drop switch, optical cross-connect switch array, and Add/Drop DWDM filter by combining MEMS actuators and PLC networks into an integrated hybrid microsystem: Micro-Opto-Electro-Mechanical System (MOEMS).

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.
