We study a 32 × 32 silicon photonic path-independent insertion loss switch used as a programmable multiport interferometer, with a robustness to optical losses appropriate for many classical and q…
Suppression of Brillouin amplifier intensity noise is demonstrated by use of a semiconductor optical amplifier (SOA) at its output to enhance application of its narrowband gain for boosting the car…
High-port-count optical switches are expected to resolve the envisaged bandwidth and power crunch in intra-data center networks stemming from the slowdown of Moore's Law. This paper briefly reviews…
We review our recent results in multi-port strictly non-blocking optical switches based on silicon photonics. Silicon photonics switches are one of the most important devices to realize future data…
Improving the efficacy of optical phase conjugation (OPC) for compensating nonlinear signal distortion in long distance optical fiber links from the Kerr effect is demonstrated. This is based on ta…
The design of a novel 1 × M fold-back type wavelength selective switch (WSS), which has fewer waveguide crossings than a conventional integrated WSS, is reported. The WSS is composed of interleave…
We investigate a large-scale and fast optical circuit switch system that uses digital coherent technologies. The achievable port count is expanded by introducing colorless detection which eliminate…
In this article, we report the development of a strictly non-blocking 8 × 8 silicon photonics switch designed to operate in the O-band. This 8 × 8 switch is based on path-independent insertion-lo…
The benefit of Brillouin amplification for optical carrier recovery from pilot tones is evaluated in application to coherent signal detection without a conventional local oscillator (LO) laser. The…
Swift and dynamic reconfigurability of network topology, even at the optical layer, is essential for satisfying the various requirements of future networks in diverse areas (e.g., data centers, 5G/…
