“…While the capacity of optical transmission systems is increasing with higher bit rates and more complex modulation schemes to meet growing bandwidth demand [1], large changes in the channel loading or input powers of the optical amplifiers can result in branching networks faults [2]. Then, dynamic gain control and spectral gain flatness become fundamental features of the optical amplifiers [2], [3].…”

“…Unfortunately, the flattened spectral gain for the full range of controlled gain values is achieved only at the expense of degraded noise figure (NF). This noise figure penalty is particularly detrimental because advanced modulation formats for high-rate channels (100 Gb/s and beyond) are being widely deployed, imposing a growing demand for better noise performance in optical amplifiers [1]- [3].…”

Abstract-A hybrid RamanlEDF amplifier topology with a novel hybrid gain control (HGC) scheme based on joint actuation to provide flattened spectral gain together with improved noise figure was developed. This paper compares the hybrid amplifier performance with the most used optical amplifier topology to provide flat spectral gain (two-stage EDFA with coupled AGC),showing an improved of equivalent noise figure (1.12-6.53 dB) with flattened spectrum for all dynamic operation range (full C band load). The hybrid amplifier yet improve the channels output OSNR along 100km SSMF span (1.67-5.04 dB) and reduces the channels OSNR degradation, enabling its use for WDM reconfigurable optical networks with 100 Gb/s advanced modulation formats transceivers.

“…Thanks to the advancement of both high-performance photonic integrated circuits (PICs) and ultrahigh-speed electronics, real-time coherent optical super channels operating at aggregate speeds of up to 500 Gb/s have become a commercial reality [2], [3]. On one side, PICs have provided a costeffective mean of realizing reliable transmitter and receiver optical front ends for advanced modulation formats, whereas state-of-the-art high-bandwidth ADCs and DSPs have allowed for reconstruction of the transmitted optical field.…”

A numerical study of the impact that manufacturing tolerances have on the performance of an InP 4 Â 4 MMI working as a 90 optical hybrid is presented, including simultaneous variations of width, thickness, and refractive index over the C and L bands. Simulation results for different figures of merit, such as optical common-mode rejection ratios (CMRRs) and phase errors, are provided for both nominal and worst case scenarios. Additionally, system simulations are performed to compute imbalance-induced power penalty. Our results indicate that the combined effect of realistic foundry tolerances on device performance is significant. In particular, a fourfold reduction is predicted between nominal ('40 nm) and worst cases ('10 nm) when optical CMRRs and phase errors are compared against Optical Internetworking Forum specifications. By contrast, a much greater bandwidth is expected at the system level (! 40 nm) if a power penalty of less than 1 dB ð@BER ¼ 10 À3 Þ is to be allowed. In fact, worst case power penalties lower than 0.25 dB are predicted over the full C band, which further proves the great potential of integrated 4 Â 4 MMIs as wide-bandwidth devices for mass production of coherent receivers using state-ofthe-art integration technologies.
