Latest Patents

Lunardi's latest patents include a "Method and apparatus for signal and switch monitoring in an optical cross connect." This invention provides various methods and apparatus for monitoring signal quality and switch operation for optical switches in an optical cross connect. The signal quality can be checked using a beamsplitter to reflect a portion of the light beam carrying the signal onto a photodetector. This device can monitor loss of signal, loss of frame, and other transmission characteristics. Additionally, the position of a switch or waveguide can be monitored by circuits that detect variable levels of resistance and capacitance based on the switch's position or by reflecting probe light beams off the back of the switching mirror. The invention also includes a method for determining if the signal quality photodetector is functioning correctly.

Another notable patent is "Connection-verification in optical MEMS crossconnects via mirror-dither." This integrated connection-verification system is designed for use in a micro-electro-mechanical system (MEMS) crossconnect device. The system applies a dithering signal, such as a sinusoidal bias, to an electrode plate associated with a micro-mirror switching element to dither the micro-mirror. The optical signal from the dithering micro-mirror is fed through a beam splitter, directing a portion of the optical signal to a photodetector. If intensity modulation in the optical signal corresponding to the frequency of the dithering signal is detected, the connection path between the desired input and output ports is verified.
