摘要
In this letter, we present new architectural perspectives in optical static RAM configurations by exploiting the wavelength dimension in address domain. We present a 2 x 4 optical RAM row decoder (RD) that relies its operation on an all-passive wavelength-selective filtering matrix (lambda-matrix), receiving WDM-formatted address bits (Wordline) as input. The 2 x 4 RD is followed by an semiconductor optical amplifier Mach-Zehnder interferometer access gate and a column decoding unit to provide complete optical RAM row access. Proof-of-concept experimental verification of a 2 x 4 optical RAM RD is shown at 10 Gb/s, providing error-free operation with a peak power penalty lower than 0.2 dB.
