Wafer-Fused 1310 nm and 1550 nm Mode-Locked Semiconductor Disk Lasers

Elyahou Kapon, Alexandru Mereuta, Vladimir Iakovlev, Alexei Sirbu, Andrei Caliman

We report on fabrication and performance of wafer fused, high power, passively mode-locked semiconductor disc lasers operating in 1310 nm and 1550 nm bands. These devices comprise gain mirrors based on InAlGaAs/InP multi quantum well active regions fused t ...

Dual-pump push-pull polarization control using stimulated Brillouin scattering

Luc Thévenaz, Sang Hoon Chin, Nikolay Primerov

Stimulated Brillouin scattering (SBS) amplification of probe signals is highly polarization dependent. Maximum and minimum gain values are associated with a pair of orthogonal states of polarization (SOP), which are related to the pump SOP. Since the maxim ...

Measurement with 2m resolution using a Raman-assisted BOTDA sensor featuring 75km dynamic range

Luc Thévenaz

We have used distributed Raman amplification to extend the measurement distance of a Brillouin Optical Time-Domain Analysis (BOTDA) sensor. We successfully demonstrate a dynamic range of 75 km with 2 meter spatial resolution. ...

Distributed Brillouin Fiber Sensor Assisted by First-Order Raman Amplification

Luc Thévenaz

Distributed optical fiber Brillouin sensors provide innovative solutions for the monitoring of temperature and strain in large structures. The effective range of these sensors is typically of the order of 20–30 km, which limits their use in certain ...
