P-doped and undoped quantum dot (QD) semiconductor optical amplifiers (SOAs) having a similar chip gain of 22-24 dB are compared with regard to their static and dynamic characteristics. Amplified spontaneous emission (ASE) spectra reveal the influenc

Wavelength-division multiplexing (WDM) has historically enabled the increase in the capacity of optical systems by progressively populating the existing optical bandwidth of erbium-doped fiber amplifiers (EDFAs) in the C -band. Nowadays, the number o

In this paper we study the wavelength-dependence of power imbalance and insertion loss in InP-based 2×2 Multi-Mode Interference (MMI) couplers as means to evaluate the design of multiband DP-IQ modulators. A system level investigation is performed o

The concept of DAC-less generation of multi-level optical signals is discussed together with its latest InP-based results. A flexible transmitter sub-assembly enabling 32 GBd M-QAM operation up to 256-QAM is shown.
A segmented modulator which shapes the optical spectrum of the modulated signal by resonating sections is presented. The modulator enhances the bandwidth of the slow driving electronics at its input. 1.5-fold 3-dB bandwidth enhancement for the driver
