Time-Resolved Cathodoluminescence Imaging

The LAB Cube is a time-resolved module that can be combined with the SPARC spectral cathodoluminescence system to assist users performing lifetime imaging and antibunching experiments. This unique and user-friendly module can be retrofitted onto any scanning electron microscope (SEM), as well as any standard or new SPARC system without any extra modification.

As the only product capable of performing g(2) imaging, the LAB Cube module can be used to perform antibunching experiments and characterize single-photo emitters at the nanoscale. When combined with a pulse electron microscope, this module improves the accuracy of lifetime imaging by performing CL-decay tracing measurements during the imaging process.

A wide range of applications, of which include semiconductors for optoelectronics, single-photon emitter systems for quantum information processing and sensing applications, can benefit from measuring time dynamics in cathodoluminescence.

The LAB Cube can be used for fundamental research and quality control, assisting people in academia, development and production environments.

Easy to Install, Straightforward Use

The Delmic LAB Cube is coupled with the SPARC system with an optical fiber, using the Fiber Coupler Module.

Installation and use are straightforward:

  • No modifications to SEM required
  • No compromises to existing hardware and functionalities
  • Measure with a continuous electron beam
  • Overnight acquisitions for more accurate measurements
  • Switch readily from lifetime imaging to any other CL mode

Schematic overview of the LAB Cube system which can be used for g(2) acquisition. SPARC CL system is coupled into an optical fiber using the fiber coupler module which sends the light to the LAB Cube system containing a Hanbury Brown-Twiss system with a beam splitter (BS) and two ultrafast Single Photon Detectors (SPDs). The signals from the detectors are read out by the time-correlator system.
