چکیده

We describe a compact modulator based on a photonic crystal nanocavity whose resonance is electrically controlled through an integrated p-i-n junction. The sub-micron size of the nanocavity promises very low capacitance, high bandwidth, and efficient on-chip integration in optical interconnects.

High-contrast electrooptic modulation of a photonic crystal nanocavity by electrical gating of graphene.

We demonstrate high-contrast electro-optic modulation of a photonic crystal nanocavity integrated with an electrically gated monolayer graphene. A silicon air-slot nanocavity provides strong overlap between the resonant optical field and graphene. Tuning the Fermi energy of the graphene layer to 0.85 eV enables strong control of its optical conductivity at telecom wavelengths, which allows modu...

Strong Optomechanical Interaction in Hybrid Plasmonic-Photonic Crystal Nanocavities with Surface Acoustic Waves

We propose dynamic modulation of a hybrid plasmonic-photonic crystal nanocavity using monochromatic coherent acoustic phonons formed by ultrahigh-frequency surface acoustic waves (SAWs) to achieve strong optomechanical interaction. The crystal nanocavity used in this study consisted of a defective photonic crystal beam coupled to a metal surface with a nanoscale air gap in between and provided ...

Design and Fabrication of an Electrically- Activated Photonic Crystal Nanocavity Laser

In the future, optical networks may see an expanded role not only in telecommunications, but also in computers and other common electronic devices. These optical networks will require small, on-chip light sources. By using the photonic crystal's ability to strongly confine light, photonic crystal lasers can be built very small and very efficient, making them ideal for photonic integrated circui...

Strong Optical Filed Intensity Improvement Introducing InGaAsP Quantum Wells in InP Nanocavity

This paper presents the optical characteristics of a quantum well doped InP nanocavity.The resonance wavelength of the nanocavity and the optical field intensity is calculated before and after presence of the quantum wells. The resulting huge filed intensity of about 1.2×108 respect to the incident field is the effect of quantum wells placed in vicinity of center of nanocavity.
