摘要： An apparatus having a topology that allows building complicated optical programmable arrays useful for manipulating the phase and/or amplitude of an optical signal. Sophisticated filtering and other optical signal processing functionality can be programmed into the array after a chip containing the array has been fabricated. This programming capability is analogous to that of electronic field programmable gate arrays (FPGA's). Apparatus described herein will provide a powerful tool for processing optical signals or very broadband electrical signals.

摘要： According to one embodiment, a microwave photonic band-stop (MPBS) filter uses an electrical input signal to drive an optical Mach-Zehnder modulator. A modulated optical carrier produced by the modulator is applied to an optical filter having at least two tunable spectral attenuation bands that are located substantially symmetrically on either side of the carrier frequency. The resulting filtered optical signal is applied to an optical-to-electrical (O/E) converter to produce an electrical output signal.

摘要： An apparatus and method for automated calibration of an optical device are disclosed. The apparatus is an integrated optoelectronic system that includes input and output optical waveguides, a tunable optical device, an optical source, an optical detector, and an electronic controller formed on a single substrate. The tunable optical device has one or more tuning elements for varying one or more characteristics of the device. The optical source is coupled to the input waveguide for providing a calibration signal to the device. The optical detector is coupled to the output optical waveguide for measuring an intensity of the optical signal output by the device in response to receiving the calibration signal. The electronic controller is configured to perform a calibration of the device by varying a parameter of each tuning element and to receive intensity measurements of the optical signal output by the device as a function of the varied parameter.

摘要： An optical digital-to-analog conversion is realized by employing either a continuous wave or pulsed laser optical signal. The laser optical signal is split into a plurality of mutually coherent optical beams, which are phase shift modulated by bits of a digital data sequence to be converted to an analog signal. The phase shift modulated optical beams are recombined to realize the desired digital-to-analog converted optical signal.
