We report the realization of a mechanically flexible microcavity laser emitting at 657 nm using spin coating. These optically pumped vertical cavity surface emitting lasers use InGaP colloidal quantum dots as the active medium and alternating polymer layers of different refractive indices as the Bragg mirrors. Results of photoluminescence measurements indicating enhancement in spontaneous emission are presented. We also demonstrate the possibility of peeling the device off the substrate yielding a flexible structure that can conform to any shape and whose emission spectra can be mechanically tuned. This new class of hybrid lasers combines advantages of organic and inorganic materials.
