Performance investigation of a hybrid fiber optical parametric amplifier

open access: yesOptics Express, 2013
We demonstrate reduction of four-wave mixing crosstalk using hybrid optical parametric amplifier with erbium-doped fiber amplifier. Crosstalk reduction of more than 13 dB has been achieved while providing 20-dB gain. Noise figures of different amplifier configurations are compared. Bit error rate measurements confirm the hybrid configuration introduces

Experimental analysis of four-wave mixing in a semiconductor optical amplifier using frequency resolved optical gating [PDF]

open access: yes, 2007
Four-wave mixing was performed in a multi-quantum well semiconductor optical amplifier in order to demultiplex 2 ps pulses from 80 GHz to 10 GHz. The demultiplexed pulses were measured using frequency resolved optical gating.

Simulating an ultra-broadband concept for Exawatt-class lasers

open access: yesScientific Reports, 2021
The rapid development of the optical-cycle-level ultra-fast laser technologies may break through the bottleneck of the traditional ultra-intense laser [i.e., Petawatt (PW, 1015 W) laser currently] and enable the generation of even higher peak-power ...

Ultra-high on-chip optical gain in erbium-based hybrid slot waveguides

open access: yesNature Communications, 2019
Realizing efficient on-chip amplification in silicon is challenging due to either non-compatible integration or small gain per unit length of the amplifier material.
