Abstract: Aspects of the present disclosure involve coherently mixing information in a first optical signal with information from one or more other optical signals, the optical signals being synchronous, to generate a mixed optical signal that obfuscates the information of the first optical signal. Each of the other optical signals is likewise mixed with a combination of the first and/or other optical signals resulting in a collection of mixed optical signals, none of which resemble the original first and other optical signals. When each of the mixed optical signals is transmitted in a separate optical fiber, then eavesdropping on only a single fiber cannot yield an unambiguous recovery of any one of the original optical signals.

Abstract: Control apparatus and methods for photonic devices are disclosed. One or more detectors is used to monitor a functional state of a photonic device. Each detector is configured to receive a respective pair of optical signals from the photonic device and generate a detection signal proportional to a difference between the pair of optical signals. A controller generates control signal(s) for the photonic device based on the detection signal(s). The apparatus and methods may be used in optical switching applications to control multiple photonic devices configured as optical switches in order to implement a multi-channel optical switch fabric for a multi-channel optical switch.

Abstract: A system and method for obfuscating an optical signal is disclosed. Obfuscating the optical signal may make it more difficult for the optical signal to be detected by an interloper. In one embodiment, an optical signal is received at an optical transmitter, and an obfuscated optical signal is generated by performing a modification of the received optical signal. The obfuscated optical signal is then transmitted from the optical transmitter to an optical receiver. An at least partially deobfuscated optical signal is generated at the optical receiver by performing a modification of the obfuscated optical signal. The modification performed at the optical receiver corresponds to the modification performed at the optical transmitter.

Abstract: Methods and apparatus for add-drop multiplexing in all optical networking are provided. A tunable optical filter is controlled to drop a first portion of an incoming optical signal in a first wavelength band and pass a second portion of the incoming optical signal in a second wavelength band. The dropped first portion is distributed among local drop optical output ports with a demultiplexer. A multiplexer combines local add optical input signals in a third wavelength band into an add optical input signal and the tunable optical filter is controlled to add the add optical input signal to the passed second portion of the incoming optical signal. The tunable optical filter is configured to lower an optical loss for the passed second portion of the incoming optical signal at the account of a corresponding increase of an optical loss in the dropped first portion and/or the add optical input signal.
