Polarization pulling in Brillouin fiber sensing using orthogonal probes

While birefringence-induced polarization fading in dual-probe Brillouin optical time-domain analysis has been demonstrated to be mitigated by using sub-mW orthogonally polarized probes, this work investigates consequences of using stronger probes. Experime ...

Observation of Fundamental Charge Noise in Electro-Optic Photonics Integrated Circuits

Tobias Kippenberg, Johann Emmeram Riemensberger, Guanhao Huang, Zihan Li, Junyin Zhang

We observed a novel 1/f-type frequency noise in Lithium Niobate and Lithium Tantalate microresonators, distinct from thermorefractive noise and originating from thermodynamic charge fluctuations, setting the linewidth limits for integrated lasers. A charge ...

Spatial Avoided Crossing in Optical Emission of Site-Controlled Pyramidal Quantum Dots in Photonic Crystal Cavities

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Alessio Massimiliano Davide Miranda

Interactions of site-controlled quantum dots with a high-order cavity mode of an L7-type photonic crystal cavity are resolved spatially and spectrally. We observed a spatial avoided crossing in polarization-resolved optical emission of quantum dots. ...

Polarization Pulling in Dual-Probe Distributed Brillouin Optical Fiber Sensors

Luc Thévenaz

This paper investigates the so-far unexplored influence of the probes on the state of polarization (SOP) of the pump pulse in a distributed fiber sensor based on dual-probe Brillouin optical-time domain analysis (BOTDA). A theoretical framework, based on a ...
