Ultra-low power parametric frequency conversion in a silicon microring resonator.
We demonstrate parametric wavelength conversion via four-wave mixing using ultra-low peak pump powers of a few milliwatts in a micrometer-scale silicon device. The response time of our device is 100 ps allowing for implementation in high-bandwidth optical communications. At these ultra-low power levels and microscale sizes, it should be possible to realize hundreds of these devices operating si...
متن کاملCompact optical temporal differentiator based on silicon microring resonator.
We propose and experimentally demonstrate a temporal differentiator in optical field based on a silicon microring resonator with a radius of 40 microm. The microring resonator operates near the critical coupling region, and can take the first order derivative of the optical field. It features compact size thus is suitable for integration with silicon-on-insulator (SOI) based optical and electro...
متن کاملDextran Modified Silicon Photonic Microring Resonator Sensors
We present a dextran modified silicon microring resonator sensor for high density antibody immobilization. An array of sensors consisting of three sensor rings and a reference ring was fabricated and its surface sensitivity and the limit of detection were obtained using polyelectrolyte multilayers. The mass sensitivity and the limit of detection of the fabricated sensor ring are 0.35 nm/ng mm a...
متن کاملEfficient modulation of 1.55 μm radiation with gated graphene on a silicon microring resonator.
The gate-controllability of the Fermi-edge onset of interband absorption in graphene can be utilized to modulate near-infrared radiation in the telecommunication band. However, a high modulation efficiency has not been demonstrated to date, because of the small amount of light absorption in graphene. Here, we demonstrate a ∼ 40% amplitude modulation of 1.55 μm radiation with gated single-layer ...
متن کاملEffective Electro-Optical Modulation with High Extinction Ratio by a Graphene-Silicon Microring Resonator.
Graphene opens up for novel optoelectronic applications thanks to its high carrier mobility, ultralarge absorption bandwidth, and extremely fast material response. In particular, the opportunity to control optoelectronic properties through tuning of the Fermi level enables electro-optical modulation, optical-optical switching, and other optoelectronics applications. However, achieving a high mo...
