In the present work, we investigate the impact of active length variation of Semiconductor Optical Amplifier (SOA) on the performance of wavelength converter based on cross-gain modulation (XGM) for different SOA active length up to 0.0004m. The system performance has been analyzed by varying input power from -9 to 10 dBm. It is found that the system gives optimum performance at SOA active leng...

Introduction: Optoelectronic circuits with high levels of circuit connectivity and nanosecond time-scale reconfigurability of massively broadband optical signals may play an increasing role in high-capacity data transfer optical networks.

The field of optics has a drastic impact in the field of electronics and communication. With the rising need for higher data transfer rate, optical advancements have served this purpose. Optical amplifiers play a crucial role in the amplification of signal at regular intervals to avoid loss of data. Erbium doped fiber amplifiers (Erbium Doped Fiber Amplifier) carry out the amplification by stim...

In millimeter-wave (mm-wave) optical double sideband (DSB) signal transmission systems, the received radio frequency (RF) power fades periodically because of the group velocity dispersion (GVD) and the self-phase modulation (SPM) of optical fibers. In this paper, cancellation of the signal fading by using midway optical phase conjugation in mm-wave subcarrier multiplexed (SCM) optical DSB signa...

We achieved first dynamic all-optical signal processing with a bandgap-engineered MZI SOA all-optical switch. The wide-gap Selective Area Growth (SAG) technique was used to provide multi-bandgap materials with a single step epitaxy. The maximum photoluminescence (PL) peak shift obtained between the active region and the passive region was 192 nm. The static current switching with the fabricated...

Semiconductor optical amplifier (SOA) is widely used for power amplification in O-band, particularly passive networks (PONs) which can greatly benefit its advantages of simple structure, low consumption and integrability with photonics circuits. However, the annoying nonlinear pattern effect degrades system performance when SOA needed as a pre-amplifier PONs. Conventional solutions mitigation a...

All-optical signal processing has been considered a solution to overcome the bandwidth and speed limitations imposed by conventional electronic-based systems. Over the last few years, an impressive range of all-optical signal processors have been proposed, but few of them come with reconfigurability, a feature highly needed for practical signal processing applications. Here we propose and exper...

Distributed Acoustic Sensor (DAS) has potential in applications such as hydroacoustic detection. In this paper, a dual-pulse heterodyne distributed acoustic sensor system using semiconductor optical amplifier (SOA)-based fiber ring laser (FRL) is proposed. Unlike the previous DAS configurations, SOA-based FRL replaces narrow linewidth (NLL) and pulse modulator, reducing costs simplifying system...

Based on self-reproduction theory, harmonic and rational harmonic mode-locked semiconductor optical amplifier (SOA) fiber ring lasers have been numerically investigated, respectively. Harmonic mode locking makes a target of obtaining ultra-short pulse. While in rational harmonic mode locking, it is urgently needed to solve that pulse amplitude becomes uneven with the increase of the order of ra...
