We created a hybrid device composed of a silicon resonator cavity coupled to a layered nanomaterial, phosphorene, that performed as an optical emitter at near-infrared telecommunications wavelengths.
Significance and Impact
There is commercial interest in a silicon-compatible laser for photonic integrated circuits as an optical analog of microelectronics. The work demonstrates a hybrid silicon-nanomaterial platform for creating optically-active devices in integrated silicon chips.
- The nanomaterial properties required to optically emit in the near-infrared telecommunications wavelengths were isolated.
- CNM tools: Near-infrared microscope and superconducting nanowire single photon detectors.
Work was performed in part at the Center for Nanoscale Materials.
About Argonne’s Center for Nanoscale Materials
The Center for Nanoscale Materials is one of the five DOE Nanoscale Science Research Centers, premier national user facilities for interdisciplinary research at the nanoscale supported by the DOE Office of Science. Together the NSRCs comprise a suite of complementary facilities that provide researchers with state-of-the-art capabilities to fabricate, process, characterize and model nanoscale materials, and constitute the largest infrastructure investment of the National Nanotechnology Initiative. The NSRCs are located at DOE’s Argonne, Brookhaven, Lawrence Berkeley, Oak Ridge, Sandia and Los Alamos National Laboratories.
