Abstract :
In plasmonic data storage a femtosecond laser pulse is focused to a diffraction-limited spot over a small region of an optical disk which contains plasmonic nano-structures. The digital information stored in each bit-cell modifies the spectrum of the femtosecond light pulse, which is subsequently detected in transmission (or reflection) using an optical spectrum analyzer. We present theoretical as well as experimental results that confirm the potential of plasmonic nano-structures for high-density optical data storage applications.
