  abstract     = {{We demonstrate an optical arbitrary waveform measurement (OAWM) system that exploits a bank of silicon photonic (SiP) frequency-tunable coupled-resonator optical waveguide (CROW) filters for gapless spectral slicing of broadband optical signals. The spectral slices are coherently detected using a frequency comb as a multi-wavelength local oscillator (LO) and stitched together by digital signal processing (DSP). For high-quality signal reconstruction, we have implemented a maximum-ratio combining (MRC) technique based on precise calibration of the complex-valued opto-electronic transfer functions of all detection paths. In a proof-of-concept experiment, we demonstrate the viability of the scheme by implementing a four-channel system that offers an overall detection bandwidth of 140 GHz. Exploiting a femtosecond laser with precisely known pulse shape for calibration along with dynamic amplitude and phase estimation, we reconstruct 100 GBd QPSK, 16QAM and 64QAM optical data signals. The reconstructed signals show improved quality compared to that obtained with a single high-speed intradyne receiver, while the electronic bandwidth requirements of the individual coherent receivers are greatly reduced.}},

  abstract     = {{Sheets of slab waveguides with sharp corners are investigated. By means of rigorous
numerical experiments, we look at oblique incidence of semi-guided plane waves. Radiation losses
vanish beyond a certain critical angle of incidence. One can thus realize lossless propagation through
90-degree corner configurations, where the remaining guided waves are still subject to pronounced
reflection and polarization conversion. A system of two corners can be viewed as a structure akin to
a Fabry-Perot-interferometer. By adjusting the distance between the two partial reflectors, here the
90-degree corners, one identifies step-like configurations that transmit the semi-guided plane waves
without radiation losses, and virtually without reflections. Simulations of semi-guided beams with
in-plane wide Gaussian profiles show that the effect survives in a true 3-D framework.}},
