Nanocavity-enhanced optical emission at telecommunications wavelengths

In a study published in Nano Letters, researchers highlight the versatility of the Si-BP material platform for creating optically active devices in integrated silicon chips.

Scientific Achievement 

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.

Research Details

  • 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.
