title: Micro-fabricated single mode polymer dye laser.
abstract: We present a single mode, single polarization, distributed feedback polymer dye laser, based on a short high order Bragg grating defined in a dye doped polymer layer between two secondary polymer layers. The Bragg grating is defined solely with standard I-line UV lithography. In this device we obtain single mode operation in a multimode structure by means of mode loss differentiation without using sub-wavelength structures. The laser is fabricated using micro-fabrication technology, is pumped by a pulsed frequency doubled Nd:YAG laser, and emits light in the chip plane at 551.39 nm, with a FWHM linewidth below 150 pm.
