We present a novel low-power architecture for the generation of multilevel pulse amplitude modulation (PAM-4) signal generation. A new structure of a micro-ring resonator based on a 44 MMI (Multimode interference) coupler is proposed to control the coupling coefficient and Fano shapes.

In the field of 24/7 human health monitoring, pervasive computing makes possible the continuous analysis of physiological parameters from an ambulatory device with a great acceptability. This paper presents two methods for obtaining cardiac and respiratory rates from a single arterial pressure signal: AM-FM demodulation and Singular Spectrum Analysis (SSA). With the aim to monitor sleep apnea, two simulated central sleep apnea were performed and recorded with Biopac reference system.

We propose a new scheme for multilevel pulse amplitude modulation (PAM-4) signaling for optical interconnects and data center networks. Our approach is to use only one 4x4 multimode interference (MMI) structure with two phase shifters in push-pull configuration.

In this paper, the expression of the signal optical pulse with the frequency-chirp propagated through the dispersive fiber is derived. This expression described the broadening of the pulse in propagating process (broadening factor), which depends on the frequence chirp and dispersive parameters. The influence of those parameters on the pulse broadening is simulated and discussed.
