    • The present invention pertains to an optical shutter (103), comprising an photon-absorbing layer (105), and a surface layer in a transparent state on at least one side of the photon-absorbing layer (105), wherein the optical shutter (103), is characterized by the absorption of photons to change the photon-absorbing layer (105), to an opaque state and to change the surface layer (15), to a reflective state. The optical shutter (103), is reversibly imageable between these transparent and reflective states. The optical shutter (103), may comprise a metallized layer on at least one side of the photon-absorbing layer. Preferably, the optical shutter comprises an organic free radical compound, such as a salt of an aminium radical cation, in the photon-absorbing layer. Also provided are optical switch devices and optical buffers (120) and (130), comprising such optical shutters and methods of switching an optical signal utilizing such optical shutters and switch devices.

    • The present invention pertains to an optical shutter (104) comprising an organic free radical compound, wherein the optical shutter (104) is reversibly imageable to switch between a non-reflective and transparent state and a reflective state. This switching may be induced by the absorption of photons, the application of an electric current, or thermally. Preferably, the organic free radical compound is a salt of an aminium radical cation. Also provided are optical switch devices and optical buffers (120) comprising such optical shutters (104), methods of switching an optical signal utilizing such optical shutters (104) and switch devices, and methods of storing an optical signal utilizing such optical buffers (120).
