All-Optical Logic Gates Based on an SOA and an Optical Filter
A novel all-optical logic device, composed of an SOA and an optical filter, is demonstrated for AND, OR and XOR gates at 10 Gb/s. Simulation indicates the device can operate at much higher bit rate.

متن کاملThe Effects of Strained Multiple Quantum Well on the Chirped DFB-SOA All Optical Flip-Flop
In this paper, based on the coupled-mode and carrier rate equations, a dynamic model and numerical analysis of a multi quantum well (MQW) chirped distributed feedback semiconductor optical amplifier (DFB-SOA) all-optical flip-flop is precisely derived. We have analyzed the effects of strains of QW and MQW and cross phase modulation (XPM) on the dynamic response, and rise and fall times of the ...
متن کاملSOA-based all-optical switch with subpicosecond full recovery.
We investigate all-optical switching in a multi-quantum-well semiconductor optical amplifier-based nonlinear polarization switch using optical pulses with duration of 200 fs at a central wavelength of 1520 nm. We show full recovery of the switch within 600 fs, in both the gain and absorption regime. We discuss the switching and recovery mechanisms using numerical simulations that are in qualita...
متن کاملAll-Optical Clocked Flip-Flops Exploiting SOA-Based SR Latches and Logic Gates
All-optical flip-flops are key components for photonic digital processing in next generation optical networks and optical computing. In most digital applications signals synchronization with an external reference clock is a basic feature. In this paper an entire set of all-optical clocked flip-flops, including SR, D, T, and JK types is proposed and demonstrated. Each configuration employs a sin...
