Area of Science:

  • Optoelectronics
  • Semiconductor Devices
  • Photonics

Background:

  • Vertical-cavity surface-emitting lasers (VCSELs) are crucial optoelectronic components.
  • Achieving stable polarization and low threshold current in VCSELs remains a key challenge.
  • Surface gratings offer a potential solution for enhancing VCSEL performance.

Purpose of the Study:

  • To fabricate and characterize low threshold current, polarization-stabilized 795 nm VCSELs.
  • To investigate the effectiveness of integrated surface gratings for polarization control.
  • To analyze the impact of grating parameters on VCSEL performance.

Main Methods:

  • Design of a high polarization selectivity and high reflectivity surface grating using rigorous coupled-wave analysis.
  • Fabrication of VCSELs incorporating the designed surface grating.
  • Experimental characterization of threshold current, polarization suppression ratio, emission wavelength, and temperature dependence.

Main Results:

  • Achieved a low threshold current of 0.4 mA.
  • Obtained a high orthogonal polarization suppression ratio (OPSR) of 19.56 dB.
  • Demonstrated stable 795 nm single transverse mode emission at 85 °C with 0.9 mA injection current.
  • Identified dependence of threshold current and output power on the grating region size.

Conclusions:

  • The integrated surface grating effectively stabilizes polarization and reduces threshold current in 795 nm VCSELs.
  • Rigorous coupled-wave analysis is a suitable method for designing high-performance gratings.
  • Grating dimensions significantly influence VCSEL operational characteristics, offering a means for device optimization.
