During the last two decades, starting with the seminal work by Cruz, network calculus has evolved as a new theory for the performance analysis of networked systems. In contrast to classical queueing theory, it deals with performance bounds instead of average values and thus has been the theoretical basis of quality of service proposals such as the IETF’s Integrated andDifferentiated Services ar...

The performance of electronic analog-to-digital converters (ADCs) at high sampling rates is fundamentally limited by the timing jitter of electronic clocks. To circumvent this limitation, one method is to exploit the orders-of-magnitude lower timing jitter of mode-locked lasers and implement optical sampling as a front-end for electronic ADCs. The optical-sampling, wavelength-demultiplexing app...

We propose and demonstrate a novel scheme for clock recovery and simultaneous fourfold optical time-division demultiplexing using a dual-parallel Mach-Zehnder modulator based optoelectronic oscillator. 25-GHz prescaled optical clock with a 23% duty cycle and a 22-dB extinction ratio is successfully extracted from both 100-Gb/s on-off keying (OOK) and differential phase-shift keying (DPSK) optic...
