Realizing dynamics in the optical layer is becoming more important for efficient optical communication networks such as protection switching in the optical domain or reconfiguring the optical layer to meet traffic fluctuations. This paper experimenta

A $4 \,\, \times \,\, 4$ Si-wire path-independent insertion-loss optical switch having off-chip polarization diversity is demonstrated. The polarization diversity is achieved using off-chip components of polarization-maintaining fiber arrays and fibe

A novel method for estimating energy consumption of networks at the national scale is presented. Accurate estimations of network energy consumption are increasingly important because of continuously increasing network traffic and the need to assess e

We study a wavelength-tunable optical parametric regenerator (OPR) demonstrated experimentally by assessing numerically its performance as an inline component of a 43-Gb/s return-to-zero differential phase-shift keying transmission system. The device

This letter presents a 10-Gb/s burst-mode clock and data recovery (BM-CDR) circuit based on an analog phase-picking method. The experiment demonstrates that the proposed BM-CDR circuit is able to align the BM data to a local clock with a phase alignm

We develop frequency-preserving parametric tunable dispersion compensator (P-TDC) with polarization diversity for simultaneous dispersion compensation of wavelength division multiplexing channels. The in-line polarization-insensitive P-TDC is compose
