Experimental study of a tunable hybrid III-V-on-silicon laser for spectral characterization of fiber Bragg grating sensors
Jean-Baptiste Quélène, Didier Pohl, David Bitauld +2
Fiber Bragg Grating (FBG) sensors offer multiple benefits in comparison with electronic sensors due to their compactness, electromagnetic immunity as well as their resistance to ha…
Design optimization of passively mode-locked semiconductor lasers with intracavity grating spectral filters
Finbarr O'Callaghan, David Bitauld, Stephen O'Brien
We consider design optimization of passively mode-locked two-section semiconductor lasers that incorporate intracavity grating spectral filters. Our goal is to develop a method for…
Timing characterization of 100 GHz passively mode-locked discrete mode laser diodes
David Bitauld, Simon Osborne, Stephen O'Brien
We report on the characterization of the timing stability of passively mode-locked discrete mode diode laser sources. These are edge-emitting devices with a spatially varying refra…
Passive harmonic mode-locking by mode selection in Fabry-Perot diode lasers with patterned effective index
D. Bitauld, S. Osborne, S. O'Brien
We demonstrate passive harmonic mode-locking of a quantum well laser diode designed to support a discrete comb of Fabry-Perot modes. Spectral filtering of the mode spectrum was ach…
Nanoscale single- and multi-photon mapping of optical fields
David Bitauld, Francesco Marsili, Alessandro Gaggero +5
The study of optical phenomena on the subwavelength scale is becoming increasingly important in photonics, particularly in the fields of nanoemitters, photonic crystals and plasmon…
Physics and application of photon number resolving detectors based on superconducting parallel nanowires
F Marsili, D Bitauld, A Gaggero +4
The Parallel Nanowire Detector (PND) is a photon number resolving (PNR) detector which uses spatial multiplexing on a subwavelength scale to provide a single electrical output prop…
