2R Regeneration

We highlight the feasibility of experimental implementation of both inverted and noninverted wavelength conversion, 2R regeneration, and all-optical logic functions, such as OR, NOR, XOR, and XNOR optical gates by exploiting the self-polarization rotation in a semiconductor optical amplifier (SOA) device without changing the setup configuration. Switching between each optical function is done by only adjusting the input optical power level. In order to allow optimum control and preserve the polarization state of the injected and collected signals, the polarimetric measures have been carried out in free space.

Abstract Semiconductor optical amplifier-based polarization rotation is utilized in designing all-optical AND gate at 100 Gbps. The AND gate shows high extinction ratio (ER ∼ 15 dB), contrast ratio (CR ∼ 18 dB) and quality factor (Q-factor ∼ 16 dB). The effect of the amplified spontaneous emission noise on the performances is also investigated. The AND gate has relative eye opening (REO) varying from 93.52 to 97.1% for 10–30 dB unsaturated gain. Using the AND gate a majority voting gate is designed and analyzed and has Q ∼ 11.7 dB with REO ∼ 91%.
