Notice: As of 2014 and for the forthcoming years, the publication frequency/periodicity of NAUN Journals is adapted to the 'continuously updated' model. What this means is that instead of being separated into issues, new papers will be added on a continuous basis, allowing a more regular flow and shorter publication times. The papers will appear in reverse order, therefore the most recent one will be on top.

Abstract: Silicon Mach-Zehnder modulator (SMZM) is fit to high-contrast optical modulation in wide ranges of spectral along 50 Gbaud symbol rates. Some times its efficiency is lower in wavelength about 1.31 μm than 1.55 μm, it can decrease the Phase Shifter (PS) efficiency and occupies large amount of data rates. In this manuscript, the plus-shaped PN junction Phase Shifter (PS) is proposed. The major aim of the proposed work is to create an optimum CD type plus-shaped PS including lesser VπL. Silicon MZM including proposed PS can satisfy the higher-speed data transmission requirement on the applications of inter with intra data centre. The objective of this method is to increase the modulation efficiency (ME) by decreasing the optical loss for higher-speed data rate (DR). To get greater efficiency of modulation, the P doped region width and the thickness of doped regions are differ under slabs. The simulation analysis of circuit-level is executed in the proposed PS acquired at travelling wave electrode (TWE) silicon Mach Zehnder modulator. In 80 Gbps, the 12.39 dB maximal extinction ratio along 8.67×10-8 bit error rate (BER) was acquired in VπLπ of 1.05 V.cm for 3.5 mm PS length. The measured intrinsic bandwidth of 3 dB denotes ~38 GHz, whereas the transmission energy per bit denotes 1.71pJ/bit. More examines are carried out to recognize the maximal communication distance using proposed PS under SMZM for the requirements of data centre.
