“…The veracity of these models has been confirmed experimentally, [24]. As mentioned above, even though the filter has a linear state space model, results from linear control theory on poleplacement do not apply, since it is the gains which play the role of the controls and these gains are embedded in the system matrices.…”

In this work, we consider design questions for an active optical lattice filter, which is being manufactured at the University of Texas at Dallas, and which has proven to be useful in the signal processing task of RF channelization. The filter can be described by a linear, discrete time state space model. The controlling agents, the gains, are embedded in the matrices intervening in this state space model. Consequently, techniques from linear feedback control theory do not apply. We concentrate on the question of finding real valued gains so that the A matrix of the state space model has a prescribed characteristic polynomial. We find that three of the coefficients can be arbitrarily picked, but that the remaining are constrained by these and the other system parameters. Our techniques use methods from constructive algebraic geometry.

“…Optical filters are key elements in integrated photonic filter design and optical communication systems especially those using the wavelength division multiplexing (WDM) technique 14,15 . WDM systems have the power to harness a huge bandwidth, and optical filters are essential to realizing this goal.…”
