    Abstract: Methods and apparatus are provided for the recognition of an optical signal that is encoded with a specified temporal pattern. Nonlinear optical interactions and time-integrating optical detectors are used to identify temporally short correlation peaks in an optical signal in an optical communication system without temporally resolving the correlation signal. The apparatus includes means for decoding an encoded optical waveform, a time-integrating nonlinear detection system, a time-integrating linear detection system for proper normalization, and thresholding electronics that produce voltage pulses corresponding to the presence of specified waveforms at the detector input.

    Abstract: Optical circuits having a flat wavelength response are disclosed. A disclosed apparatus includes a first optical coupler, first and second optical waveguides optically coupled to the first optical coupler and a second optical coupler optically coupled to the first and second optical waveguides. The first optical coupler couples input light into a first portion and a second portion. The first and second optical waveguides receive the first and second portions of input light from the first optical coupler, respectively the second optical coupler couples the first portion of input light from the first optical waveguide and the second portion of input light from the second optical waveguide. The second optical waveguide may effect a fixed phase difference of one-half wavelength relative to the input light. The first and second optical couplers may have first and second wavelength dependences, respectively, where the second wavelength dependence is opposite the first wavelength dependence.

    Abstract: A signal may be split by a splitter into a plurality of output signals. Each of these output signals may then be amplified. Amplified spontaneous emission noise may be removed using a tunable filter for each of the signal outputs. As a result, an output signal may be provided with greater power so that, in some embodiments, a single split signal may be utilized to service more end users.

At least one grating is coupled to the fiber of each waveguide and at least one phase shifter coupled to the fiber of at least one waveguide. The phase shifter controls a phase profile of light passing through the fiber to control a profile of a laser beam reflected at the grating. The gratings reflect light passing through the fibers outside of the optical coder to form a laser beam shaped and directed by the grating and phase shifters. Further, a detector is coupled to the waveguides that is enabled to receive light reflected off the gratings. Other embodiments are described and claimed.
