摘要： An apparatus and method for photonically sampling an analog signal and encoding the photonically sampled signal. The two interferometer arms of a Mach-Zehnder interferometer section are directly coupled to the dual input ports of a directional coupler switch section. Optical pulses transmitted through the interferometer arms are phase shifted in proportion to an analog signal applied at the electrical input port of the Mach-Zehnder interferometer section. The phase-shifted pulses in each interferometer arm are coupled in the directional coupler switch section and are directed to the dual output ports of the directional switch section based upon the binary code applied to the electrical input port of the directional coupler switch section. The directional switch section has an optical length designed to provide a net phase shift of 3&pgr;/4.

摘要： A time delay network for phased array antenna beam steering employs a waveguide network as the delay element in a monolithic integration with other optical and electronic elements on a single substrate. A plurality of optical time delay stages are cascaded to form the delay network, with each stage having a selectable delay time. Each stage preferably has a reference or nominal time delay branch, and at least one other finite time delay branch. The lengths of the delay waveguides vary from stage to stage, permitting a high time delay resolution with a relatively small number of separate waveguides. The desired time delay is selected either by directing the modulated laser light into only one of the waveguide branches in each stage by means of waveguide switches or by splitting the light into all the waveguide branches of a stage and then activating only the detector connected to the desired delay waveguide. A variety of cascading schemes and waveguide layouts can be used to implement the time delay network.

摘要： A method of performing analog to digital conversation of an analog signal Vin(t), the method including the steps of: utilizing both of the complementary arms of an electro-optic modulator to recover the analog input signal Vin(t), while using only one time-stretch element and one λ-demultiplexer after the electro-optic modulator. The single time-stretch element and one λ-demultiplexer serve to stretch and demultiplex the signals from both of the complementary output arms of the electro-optic modulator thereby improving and simplifying post-processing algorithms used to correct for static distortions and nonlinearities that originate from imperfect photonic hardware. Double-balanced photoreceivers are preferably coupled to outputs of the single λ-demultiplexer. The single time-stretch element is preferably implemented by a chirped fiber grating. Apparatus for carrying out the method is described.
