초록

An optical memory material includes a two-photon storage component which can be written from a first to a second state in response to WRITE light, mixed with a signal component which fluoresces by one-photon absorption only at the written locations in response to READ light. The storage material may be a fulgide. The memory material may also include a frequency upconversion material to aid writing. Writing is performed by a spatial light modulator (SLM) with a dynamic focussing system, for concentrating sufficient power at WRITE locations for nonlinear t...

청구항

An optical memory material, comprising: a fulgide storage component which converts from a first state to a second state in response to two-photon absorption of WRITE light; and a signal component which responds to one-photon absorption by fluorescing only at locations at which said storage component is in one of said first and second states, and not in the other one of said first and second states.
