摘要： System and methods for all-optical signal regeneration based on free space optics are described. In one exemplary embodiment, a method for regenerating an optical signal comprises counter-propagating an input signal and a regenerating signal within an all-optical signal regenerator based on free space optics, where the all-optical signal regenerator based on free space optics comprises a Sagnac loop interferometer, and extracting a regenerated output signal from the Sagnac loop interferometer. In another exemplary embodiment, an all-optical signal regenerator based on free space optics comprises a Sagnac loop interferometer, an optical signal input path coupled to a semiconductor optical amplifier of the Sagnac loop interferometer, a regenerating optical signal path coupled to the semiconductor optical amplifier of the Sagnac loop interferometer, and a regenerated optical output path coupled to the Sagnac loop interferometer.

摘要： The invention consists of a system and method for regenerating and converting optical signals. The invention provides both “2R (i.e. reamplification and reshaping) and “3R” (i.e. reamplification, reshaping, and resynchronization (or retiming)) regeneration. The components of the inventive system include a tunable continuous wave (CW) laser source, an optical circulator, an semiconductor optical amplifier (SOA), and a spectral filter that has a very sharp cutoff frequency. In alternative embodiments, the filter may be replaced with an interleaver that passes several wavelengths. A single interleaver may be used by several of the optical regenerators/converters described herein. Each regenerator uses a separate wavelength that is associated with a passband frequency of the single interleaver. During counter-propagation in the SOA, a CW signal from the CW laser is chirped by bits in an input signal. The chirped signal is then output to the filter, which blocks the original CW signal.
