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： The inventors propose herein a novel band filter design for planar lightwave circuits. In one embodiment of the present invention, the band filter includes two waveguide grating routers connected by sets of substantially equal path length waveguides within each set separated on one side, wherein the waveguides of each set are formed such that optical signals having overlapping frequency ranges are propagated through adjacent waveguides. In addition, the waveguides of each set are spaced at their connection to the second waveguide grating router such that optical signals with predetermined optical frequency ranges are routed to selected, respective output ports. Some of the advantages of this novel band filter include compactness, sharp passband corners, and a lack of chromatic dispersion.

摘要： Spot-size conversion for interfacing a first optical element having a higher refractive index to a second optical element having a lower refractive index is achieved through the use of two optical star couplers coupled to each other through a plurality of optical paths embedded in a planar waveguide. The beam from the high refractive index element is introduced into a high numerical aperture (NA) star coupler, which directs the beam through a plurality of optical paths to a second star coupler with a lower numerical aperture than the first star coupler so that its output spot-size is larger. The output port of the second star coupler is interfaced to the lower refractive index element. Wavelength tunability can be provided by including phase shifters in the paths between the two star couplers to alter the effective optical lengths of the paths to selectively produce the desired phase interference pattern.
