Low-voltage, high speed, compact silicon modulator for BPSK modulation.
A low voltage, high speed, compact silicon Mach-Zehnder Interferometer (MZI) modulator for Binary Phase Shift Keying (BPSK) modulation has been demonstrated. High modulation efficiency, VπLπ equals to 0.45V·cm, was obtained in a 1mm length device owing to a higher doping concentration and low-loss traveling-wave electrode. 25 Gb/s non-return-to-zero(NRZ)-BPSK with 6Vpp RF driving signal was ach...
متن کاملHigh speed silicon Mach-Zehnder modulator.
We demonstrate a silicon modulator with an intrinsic bandwidth of 10 GHz and data transmission from 6 Gbps to 10 Gbps. Such unprecedented bandwidth performance in silicon is achieved through improvements in material quality, device design, and driver circuitry.
متن کاملCompact 1D-silicon photonic crystal electro-optic modulator operating with ultra-low switching voltage and energy.
We demonstrate a small foot print (600 nm wide) 1D silicon photonic crystal electro-optic modulator operating with only a 50 mV swing voltage and 0.1 fJ/bit switching energy at GHz speeds, which are the lowest values ever reported for a silicon electro-optic modulator. A 3 dB extinction ratio is demonstrated with an ultra-low 50 mV swing voltage with a total device energy consumption of 42.8 fJ...
متن کاملUltra-low voltage, ultra-small mode volume silicon microring modulator.
We show GHz modulation in a 2.5 microm radius silicon micro-ring, with only 150 mV peak-peak drive voltage and an electro-optic modal volume of only 2 microm(3). The swing voltage and the micro-ring modulator are the smallest demonstrations so-far in silicon. The presented approach lays the ground work for a new class of high speed low voltage modulators enabling, seamless integration of nanoph...
متن کاملDesign of a low cost BPSK modulator/demodulator for a practical teaching of digital modulation techniques
Teaching the digital transmission techniqueslike other fields of electronicis not always easy : There is classically theoretical courses and practical lessons. The link between the two is often the most important difficulty that appears for the students. An abundant literature on digital wireless, including high mathematical level approaches is available; since a few years, theoretical courses ...
