Control of dual-wavelength laser emission via optical feedback phase tuning
Robert Pawlus, Stefan Breuer, Martin Virte
We propose and demonstrate a technique to control the balance between the two amplitudes of a dual-wavelength laser based on a phase-controlled optical feedback. The feedback cavit…
Dual-wavelength lasers on generic foundry platform
Robert Pawlus, Robbe de Mey, Stefan Breuer +1
We propose and implement four simple and compact dual-wavelength laser concepts integrated in a Photonic Integrated Circuit (PIC) based on a InP generic foundry platform. In a firs…
In-phase and anti-phase synchronization in a laser frequency comb
Johannes Hillbrand, Dominik Auth, Marco Piccardo +5
Coupled clocks are a classic example of a synchronization system leading to periodic collective oscillations. This phenomenon already attracted the attention of Christian Huygens b…
3D-printable portable open-source platform for low-cost lens-less holographic cellular imaging
Stephan Amann, Max von Witzleben, and Stefan Breuer
Digital holographic microscopy is an emerging potentially low-cost alternative to conventional light microscopy for micro-object imaging on earth, underwater and in space. Immediat…
