Coherent multi-mode dynamics in a Quantum Cascade Laser: Amplitude and Frequency-modulated Optical Frequency Combs
Carlo Silvestri, Lorenzo Luigi Columbo, Massimo Brambilla +1
We cast a theoretical model based on Effective Semiconductor Maxwell-Bloch Equations and study the dynamics of a multi-mode mid-Infrared Quantum Cascade Laser in Fabry Perot with t…
A Simple Coupled-Bloch-Mode Approach To Study Active Photonic Crystal Waveguides and Lasers
Marco Saldutti, Paolo Bardella, Jesper Mørk +1
By applying a coupled-Bloch-mode approach, we have derived a simple expression for the transmission properties of photonic crystal (PhC) line-defect waveguides with a complex refra…
Coupled Bloch-Wave Analysis of Active PhC Waveguides and Cavities
Marco Saldutti, Jesper Moerk, Paolo Bardella +2
A coupled Bloch-wave approach is employed to analyze active photonic-crystal (PhC) waveguides and cavities. Gain couples the otherwise independent counter-propagating Bloch modes.…
Self-pulsing in single section ring lasers based on Quantum Dot materials: theory and simulations
Lorenzo Luigi Columbo, Paolo Bardella, Mariangela Gioannini
We studied theoretically coherent phenomena in the multimode dynamics of single section semiconductor ring lasers with Quantum Dots (QDs) active region. In the unidirectional ring…
Self-generation of optical frequency comb in single section Quantum Dot Fabry-Perot lasers: a theoretical study
Paolo Bardella, Lorenzo Luigi Columbo, Mariangela Gioannini
Optical Frequency Comb (OFC) generated by semiconductor lasers are currently widely used in the extremely timely field of high capacity optical interconnects and high precision spe…
