Unique Performing of g(2) Imaging and Antibunching Experiments - Lab Cube

The LAB Cube is a time-resolved module for the SPARC spectral cathodoluminescence system, which allows the performance of lifetime imaging and antibunching experiments. Delmic LAB Cube module is a unique, easy-to-use system, which can be retrofitted on any Scanning Electron Microscopy and 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 for antibunching experiments, as well as during the characterization of single-photo emitters, both of which can be performed at the nanoscale.

When combined with a pulse electron microscope, the LAB Cube has demonstrated its ability to perform highly accurate lifetime imaging, during which it can acquire CL-decay tracing measurements.

A wide range of applications, such as 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 those 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:

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

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.
