Abstract

original image

Organic lasers that rely on sinusoidal, tunable distributed-feedback gratings formed by self-organization of the surface of elastomeric PDMS are demonstrated. The lasing wavelength can be tuned by stretching. The simple fabrication of the lasers on potentially large areas enables entirely new applications such as a strain-sensing optical skin for structural health monitoring.
