Dye-Doped Mesostructured Silica as a Distributed Feedback Laser Fabricated by Soft Lithography
Source abstract
Abstract
Distributed feedback (DFB) laserswere made on silicon substrates by using elastomeric stamps to pattern dye-doped mesostructured silica into ridge waveguides with a grating on top. The emission spectra of the lasers have several peaks with a full width at half maximum of 0.3 nm (see Figure). The lasers were photopumped and had a lasing threshold intensity of ∼55 kW/cm2.
