Area of Science:

  • Optics and Photonics
  • Quantum Electronics
  • Terahertz Technology

Background:

  • Terahertz quantum cascade lasers (TQCLs) are crucial for spectroscopy and imaging.
  • Achieving tunable emission in TQCLs is essential for advanced applications.
  • Current tuning methods often face limitations in range or complexity.

Purpose of the Study:

  • To demonstrate a novel tuning mechanism for TQCLs using coupled microcavities.
  • To investigate the anti-crossing effect for laser frequency control.
  • To validate the tuning range and underlying physics with experimental data and modeling.

Main Methods:

  • Fabrication of a distributed-feedback TQCL integrated with a coupled microcavity.
  • Experimental measurement of the laser's emission frequency under varying coupling conditions.
  • Utilizing a finite element model to simulate and analyze the anti-crossing phenomenon and coupling strength.

Main Results:

  • Successfully tuned the TQCL emission frequency via anti-crossing of coupled microcavity eigenfrequencies.
  • Achieved a significant tuning range of 20 GHz in a proof-of-concept experiment.
  • Experimental results showed good agreement with the finite element model predictions.

Conclusions:

  • The coupled microcavity approach provides an effective method for tuning TQCLs.
  • The tuning range is directly related to the coupling strength between resonators.
  • This technique offers a promising pathway for developing widely tunable TQCLs, especially at lower frequencies.
