We developed a new surface-emitting superluminescent diode that prevents lasing using detuned grating outcouplers. This laser diode achieves a shaped beam with 1.5 W peak power and an 11 nm bandwidth.

Area of Science:

  • Optoelectronics
  • Semiconductor devices
  • Laser technology

Background:

  • Superluminescent diodes (SLDs) are crucial for applications requiring high power and broad spectral bandwidth.
  • Suppressing lasing in high-power devices is essential for maintaining superluminescent properties and achieving desired beam characteristics.
  • Novel configurations are needed to enhance the performance and reliability of SLDs.

Purpose of the Study:

  • To investigate a novel surface-emitting superluminescent diode (SLD) configuration.
  • To suppress unwanted lasing in high-power SLDs.
  • To achieve a shaped beam output with specific power and bandwidth characteristics.

Main Methods:

  • Designed a surface-emitting superluminescent diode.
  • Incorporated two detuned grating outcouplers to suppress lasing.
