TL;DR: It is proven that such an architecture has significant advantages with respect to a straightforward architecture using double sideband modulation and direct detection, namely relaxed bandwidth requirements on the optical modulators and detectors, reduced complexity and optical losses of the beam forming chip, and enhanced dynamic range.

TL;DR: The functionalities of the proposed MWP beamformer circuits incorporate two major signal processing functionalities, namely a broadband beamforming network employing ring resonator-based delay lines and an optical sideband manipulator that renders the circuit outputs equivalent to those of intensity-modulated M WP beamformers.

TL;DR: In this paper, the principles of optical beam forming using ORRs are explained and demonstrated, by presenting measurements on a 1times4 OBFN chip, realized in LPCVD waveguide technology.

TL;DR: A passive filter chip that functions as an optical Nyquist-filtering interleaver featuring sub-GHz resolution and a near-rectangular passband with 8% roll-off is presented, which is highly promising for high-spectral-efficiency Nyquist wavelength division multiplexed (N-WDM) optical super-channels.

TL;DR: In this paper, a photonic integrated circuit was used as an optical signal processor with an unprecedented combination of reconfigurability and terahertz bandwidth. But, the performance of the photonic IC was limited to 1.2ps-duration optical pulses at 1550 nm.
