چکیده
In this Letter, we demonstrate a highly efficient, compact, high-contrast and low-loss silicon slow wave modulator based on a traveling-wave Mach-Zehnder interferometer with two 500 μm long slow wave phase shifters. 40 Gb/s operation with 6.6 dB extinction ratio at quadrature and with an on-chip insertion loss of only 6 dB is shown. These results confirm the benefits of slow light as a means to enhance the performance of silicon modulators based on the plasma dispersion effect.

10 Gb/s broadband silicon electro-optic absorption modulator
Article history: Received 9 December 2009 Received in revised form 22 March 2010 Accepted 22 March 2010 Here we propose a design for a novel broadband silicon electro-optic absorption modulator. The device is simply a 100 μm long silicon waveguide with a Schottky diode integrated in it. Modulation is achieved through free-carrier absorption, not interference effects, enabling operation over the...
متن کاملUltracompact (3 μm) silicon slow-light optical modulator
Wavelength-scale optical modulators are essential building blocks for future on-chip optical interconnects. Any modulator design is a trade-off between bandwidth, size and fabrication complexity, size being particularly important as it determines capacitance and actuation energy. Here, we demonstrate an interesting alternative that is only 3 μm long, only uses silicon on insulator (SOI) materia...
متن کاملHigh speed hybrid silicon evanescent Mach-Zehnder modulator and switch.
We demonstrate the first high speed silicon evanescent Mach Zehnder modulator and switch. The modulator utilizes carrier depletion within AlGaInAs quantum wells to obtain V(pi) L of 2 V-mm and clear open eye at 10 Gb/s. The switch exhibits a power penalty of 0.5 dB for all ports at 10 Gb/s modulation.
متن کاملPINIP based high-speed high-extinction ratio micron-size silicon electrooptic modulator.
We propose an electrooptic device in silicon based on a p-i-n-i-p device structure for charge transport. The proposed device exhibits carrier injection time of 10 ps and extraction time of 15 ps enabling 100 GHz operation. When integrated into a resonator the proposed micron-size device operates at 40 Gb/s with 12 dB extinction ratio and 4fJ/bit/micron-length power dissipation, limited in speed...
متن کاملCompact and fast photonic crystal silicon optical modulators.
We demonstrate the first sub-100 μm silicon Mach-Zehnder modulators (MZMs) that operate at >10 Gb/s, by exploiting low-dispersion slow-light in lattice-shifted photonic crystal waveguides (LSPCWs). We use two LSPCW-MZM structures, one with LSPCWs in both arms of the MZM, and the other with an LSPCW in only one of the arms. Using the first structure we demonstrate 10 Gb/s operation with a operat...
