    We developed a single-mode, single-polarization liquid dye laser using a Bragg grating in a polymer layer. This laser technology is ideal for integration into lab-on-a-chip microsystems.

    Area of Science:

    • Photonics and Optical Engineering
    • Materials Science
    • Microfabrication

    Background:

    • Distributed feedback (DFB) lasers are crucial for integrated photonics.
    • Achieving single-mode operation in multimode structures remains a challenge.
    • Liquid dye lasers offer tunable emission but often lack integration capabilities.

    Purpose of the Study:

    • To present a novel single-mode, single-polarization DFB liquid dye laser.
    • To demonstrate integration of laser functionality into planar waveguides.
    • To enable applications in polymer-based lab-on-a-chip microsystems.

    Main Methods:

    • Fabrication of a DFB laser using microfabrication technology on a polymer layer between glass substrates.
    • Utilizing a high-order Bragg grating for laser action.
