Latest Patents

Flettner's latest patents showcase his expertise in measuring linear and non-linear transmission perturbations in optical transmission systems. His first patent involves a sophisticated system designed to measure non-linear noise at an optical transceiver. This system leverages a processor to process a reference correlation of the transmission of a fiber link channel, record the optical power spectrum, and determine the channel's baud rate. Furthermore, it applies spectral correlation techniques across multiple baud rate distances within the frequency domain. The system also calculates a generalized optical signal-to-noise ratio (gOSNR) and assesses the non-linear noise contributions by comparing the gOSNR with wavelength division multiplexed (WDM) OSNR measurements.

In his second recent patent, Flettner developed a device aimed at measuring the optical signal-to-noise ratio (OSNR) of WDM optical signals comprising multiple wavelength channels. This device includes a tunable optical filter for selecting specific optical wavelength channels, a polarization controller for adjusting the polarization state, and a control unit for calculating the OSNR based on targeted control points.
