Abstract: Systems and methods are provided herein for implementing a hybrid communications network including both radar and radio communications devices. These systems and methods may advantageously include shared resource allocation protocols for automatically allocating communication resources for transmitting and/or receiving a signal using a device in the network based on one or more dimensions of separability for the signal selected from time-division, frequency-division, spatial-division and/or code-division multiplexing. Importantly, the resource allocation protocol may account for radar specific operational parameters of one or more radar devices in the network.

Abstract: A simple, low-power feedback control loop is arranged to set the operating point of a photonic intensity modulator. The loop includes photodetectors which are respectively illuminated with a sample of the carrier signal into the modulator and the modulated signal out of the modulator. A comparison network develops an error signal which is integrated and applied to the voltage modulating port of the modulator. The comparison network includes voltage dividers for adjusting the transfer function operating point of the modulator. The control loop is especially suited for stabilizing Mach-Zehnder and directional coupler modulators.
