Abstract: An apparatus and method are provided for manipulating light beams propagated through PLCs in free space. Light beams propagated in through an input/output waveguide of a PLC are propagated through a waveguide array to generate a phased array output at an edge facet of the PLC. The phased array output at the edge facet is spatially Fourier transformed by a lens in free space, generating a spectrally resolved image at the back focal plane of the lens. The spectrally resolved image is reflected, at least in part, by a reflector device and coupled into a desired waveguide array of a PLC to produce a desired output.

Abstract: Wavelength-selective switches (WSSs) having embedded multiplexer or demultiplexer functionality include a stack of planar waveguide circuits (PLCs) in which all but one of the PLCs have identical features consisting of a single waveguide connected to a free space region, further connected to a waveguide array that terminates at the PLC edge facet, which are placed at the front focal plane of a lens, generating a spectrally resolved optical signal at the back focal plane of the lens. Due to the use of a single lens, the spectrally resolved optical signal of all the PLCs are superimposed, differing only by propagation direction. A tilting micro-mirror array at the back focal plane reflects the spectral components, implementing a wavelength-selective switch. The reflected light can couple to any of the remaining PLCs, for multiplexing, or to the different PLC in the stack, which implements the multiplexer/demultiplexer.

Abstract: An apparatus and method are provided for manipulating light beams propagated through an optical apparatus that includes a planar lightwave circuit (PLC) and free-space optics unit. A multi-wave optical signal coupled to the PLC is propagated through a first and second waveguide array to generate a phased array output at an edge facet of the PLC. The phased array output at the edge facet is spatially Fourier transformed by the lens to generate a spectrally resolved image having a discrete light spot for each channel of the input optical signal, which is coupled to a pixelated optical receiving unit. When the optical receiving unit is a reflector, one or more of the discrete light spot are reflected to a desired waveguide array of a PLC to produce a desired output. When the optical receiving unit is a pixelated transmissive modulator, one or more of the discrete light spot are modulated as they pass through the modulator.

Abstract: 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.
