A system for mechanically tuning optical wavelengths emitted from an organic
laser
cavity device, that includes: a multi-layered film structure, wherein the multi-layered
film structure is pumped by an incoherent source of photons; and a micro-electromechanical
mirror assembly proximate to the multi-layered film structure, wherein the micro-electromechanical
mirror assembly varies the cavity length of the organic laser cavity device.
