    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： A multi-channel optical equalizer for intersymbol interference mitigation compensates for single- or multi-wavelength channels simultaneously and requires few adjustable parameters. The optical equalizer also compensates for overshoots and signal transition degradations in semiconductor optical amplifiers. The equalizer unit uses one control signal for magnitude and one to control signal phase. The equalizer includes a controllable coupling ratio coupler for splitting the light into two portions and a controllable interferometer having two arms, one arm having an additional delay which is equal to an integer multiple of 1/Δf, where Δf is the channel spacing between adjacent wavelengths utilized in the optical system. The controllable interferometer has a controllable delay in a first or second arm for adjusting the relative phase of the light passing therethrough. A coupler combines the two signal portions from the first and second arms to form the equalized output signal. A multistage optical equalizer is implemented using a plurality of optical signal equalizers.

    摘要： An optical device includes a substrate with first and second arrays of optical couplers located along a planar surface thereof. The optical couplers of the first array are laterally arranged along the surface to end-couple in a one-to-one manner to corresponding optical cores of a first multi-core fiber whose end is facing and adjacent to the first array. The optical couplers of the second array of optical couplers are laterally arranged along the surface to end-couple in a one-to-one manner to corresponding optical fiber cores of one or more optical fiber ends facing and adjacent to the second array. An optical switch network is optically connected to selectively couple some of the optical couplers of the first array to the optical couplers of the second array in a one-to-one manner.
