摘要： A linear optical sampling apparatus, temporally samples a modulated optical signal using the amplitude of the interference of its electric field with the electric field of a laser pulse. The apparatus includes a 90° optical hybrid that combines the optical signal and laser pulse in order to generate two quadratures interference samples SA and SB. A processor compensates for optical and electrical signal handling imperfections in the hybrid, balanced detectors, and A/D converters used in the optical sampling apparatus. The processor numerically scales the two quadratures interference samples SA and SB over a large collection of samples by imposing that the average = =0 and = and then minimizes 2 /( + )=cos(φB−φA)). This is done by adjusting the phase between the two quadratures (ideally either −π/2 or +π/2) so that cos(φB−φA)) is zero. The processor then generates a demodulated sample signal using the quadratures interference samples SA and SB. According to one feature, the hybrid sets the relative phase between two quadratures of their interferometric component so that the phase sensitivity inherent to linear optics is removed. A variety of hybrid arrangements is disclosed that can be implemented using integrated waveguide technology. The apparatus enables sampling of picosecond pulses up to 640 Gb/s with high sensitivity and temporal resolution.

摘要： Pulse measurement for characterization of ultra-short optical pulses using spectral phase interferometry for direct electric field reconstruction (SPIDER) is enhanced by utilizing a plurality of spectral phase differences derived from the pulse and measured and frequency sheared replicas, which are temporally and/or spatially displaced, thereby providing spatial or temporal characterization or enhancing the temporal characterization of the input pulse in amplitude and phase. Improved interferometry which is not reliant on non-linear elements can be used.

摘要： Methods and apparatus are provided for transmitting alternate-polarization phase-shift-keyed data. The output of a laser is modulated to optically encode electronic data using phase shift keying (PSK) to generate an optical signal. An alternate polarization PSK (APol-PSK) signal is generated by alternating the polarization of the optical signal using a modulator such that successive optical bits have substantially orthogonal polarizations.

摘要： An optical sampling method and apparatus are provided for modulating an optical signal using a first electroabsorption modulator (EAM) driven by a sinusoidal RF voltage signal to provide substantially jitter free temporal gating of the optical signal. The gated optical signal from the first EAM is routed through a second EAM to provide an optical output signal having a reduced repetition rate. The second EAM is driven using an electrical pulse train having a repetition rate that is a subharmonic of the frequency of the sinusoidal RF voltage signal driving the first EAM.

摘要： Method and apparatus embodiments of the invention are directed to mitigating temporal contrast degradation in optical parametric chirped pulse amplification (OPCPA) laser systems. A spectral filter is used in an OPCPA laser system to remove or reduce of out-of-band amplified spontaneous emission (ASE) from an amplified pump pulse and/or the longitudinal modes of a seed laser used to generate the pump pulse, which typically cause detrimental temporal intensity fluctuations in the amplified pump signal. According to an illustrative embodiment, a volume Bragg grating (VBG) filter element is disposed in the pump regenerative amplifier cavity where the pump pulse undergoes multiple passes on the filter element.

摘要： Temporal phase shifts induced by cross-phase modulation in an optical fiber are directly characterized with a spectral equivalent of the Foucault technique used to spatially resolve wavefronts. The temporal phase induced by a high power pulsed pump on a monochromatic probe via cross-phase modulation is converted in a temporal intensity modulation via spectral filtering. A measurement of the modulated instantaneous power of the filtered signal allows to directly determine the time-resolved nonlinear phase shift. Additionally, an equivalent of the transport-of-intensity equation, which links the evolution of the instantaneous power of the electric field in a dispersive medium to the instantaneous values of the power and phase of the field. This derivation permits the measurement of temporal phase shifts using only intensity information in a direct, non-interferometric manner.
