摘要	We report on the fabrication and characterization of an organic distributed feedback laser excited from a semiconducting polymer gain layer, poly(2-methoxy-5-(2 '-ethyl-hexyloxy)-p-phenyl-envinylene) (MEH-PPV). A holographic polymer dispersed liquid crystal grating is fabricated on top of the homogeneous MEH-PPV layer as an external cavity. We established a model to calculate the confinement factor Gamma. With the change of laser structural parameters (the refractive index of the grating layer, the film thickness of the MEH-PPV layer, etc.), the confinement factor Gamma changes accordingly. It was found that a single longitudinal lasing mode could be observed only when the confinement factor Gamma was in a specific range. Choosing a reasonable thickness of gain film and prepolymer with higher refractive index can obtain a lower threshold emission laser.
