Researchers developed all-polymer lasers using co-extrusion and compression-molding. These distributed Bragg reflector (DBR) lasers demonstrate efficient lasing with tunable wavelengths, suitable for high-throughput manufacturing.

Area of Science:

  • Polymer Science
  • Optoelectronics
  • Materials Science

Background:

  • All-polymer lasers offer potential for flexible and low-cost optoelectronic devices.
  • Previous fabrication methods for polymer laser components have limitations in scalability and efficiency.

Purpose of the Study:

  • To develop and characterize melt-processed all-polymer lasers utilizing distributed Bragg reflectors (DBRs).
  • To demonstrate the feasibility of high-throughput manufacturing for polymer laser components.

Main Methods:

  • Fabrication of DBR resonators using multilayer co-extrusion of poly(styrene) (PS) and poly(methyl methacrylate) (PMMA).
  • Preparation of gain media via compression-molding of thermoplastic polymers doped with organic laser dyes.
  • Optical pumping of assembled DBR laser devices.

Main Results:

  • Achieved single and multimode lasing within the DBR resonator's reflection band.
  • Demonstrated a slope efficiency of nearly 19% and low lasing thresholds of 90 microJ/cm(2).
  • Showcased tunability of lasing wavelength by altering DBR layer thickness and laser dye selection.

Conclusions:

  • Melt-processed all-polymer DBR lasers can be fabricated using scalable co-extrusion and compression-molding techniques.
  • The developed laser architecture is compatible with high-throughput roll-to-roll manufacturing.
  • Experimental results align with theoretical models for end-pumped lasers, validating the device design and performance.
