All-optical half adder using cross gain modulation in semiconductor optical amplifiers
Optics Express, 2006•opg.optica.org
By using the gain nonlinearity characteristics of semiconductor optical amplifier, an all-
optical binary half adder at 10 Gbps is demonstrated. The half adder operates in a single
mechanism, which is cross gain modulation. The half adder utilizes two logic functions of
SUM and CARRY, which can be demonstrated by using XOR and AND gates, respectively.
The extinction ratios of both XOR and AND gates are about 6.1 dB. By achieving this
experiment, we also explored the possibilities for the enhanced complex logic operation and …
