Nanosecond-scale discrete wavelength switching in feedback-controlled single-gain-section multi-wavelength lasers

Mathieu Ladouce, Pablo Marin-Palomo, Martin Virte

We investigate discrete wavelength switching in single-gain-section multi-wavelength lasers monolithically integrated on InP with phase-controlled optical-feedback. By modulating t…

Polarization Dynamics in VCSELs Under Sinusoidal Signal Modulation around the Polarization Switching point

Salah Guessoum, Tushar Malica, Athanasios Kyriazis +3

Vertical-Cavity Surface-Emitting Lasers (VCSELs) combine compact geometry, low threshold current, and ease of integration, making them central to modern photonic systems. However,…

Theoretical analysis of optical feedback-controlled emission of dual-wavelength lasers

Mathieu Ladouce, Pablo Marin-Palomo, Martin Virte

Dual and multi-wavelength lasers, i.e., lasers with the ability to emit at two or more wavelengths in a controlled fashion, represent an exciting new twist in laser physics. Harnes…

Agile and Broadband All-Optical Wavelength Conversion with Multi-Wavelength Lasers

Pablo Marin-Palomo, Shahab Abdollahi, Mathieu Ladouce +1

We demonstrate a novel approach to all-optical wavelength conversion (AOWC) using a monolithically integrated InP multi-wavelength laser (MWL). By exploiting carrier-induced gain m…

Response of a multi-wavelength laser to single-sideband optical injection

Shahab Abdollahi, Pablo Marin-Palomo, Martin Virte

Single-mode semiconductor lasers subject to optical injection have been shown to trigger a wide range of dynamical behavior from injection locking to chaos. Multi-wavelength lasers…
