Reliability characteristics of microfabricated Rb mini-lamps for optical pumping in miniature atomic clocks and magnetometers

Nico de Rooij, Herbert Shea, Yves Pétremand, Vinu Lalgudi Venkatraman

With the rising need for microfabricated chip-scale atomic clocks to enable high precision timekeeping in portable applications, there has been active interest in developing miniature (

Field curvature correction in multichannel miniature imaging systems suited for wafer-level production

Hans Peter Herzig, Toralf Scharf, Nicolas Bongard

Using multiple optical channels increases the number of design possibilities for the objectives of mobile imaging devices. For easy wafer-level fabrication, we start from a single optical element-a monocentric plano-convex lens. The quality of the areal im ...

Millimeter-sized cobalt doped rutile crystals with a bi-pyramidal shape are obtained by chemical vapour transport using scroll-type H2Ti3O7 nanotubes as a precursor in which Co2+ ions are introduced by a simple ion exchange method prior to the growth. Desp ...

l Here we present unique evidence of a k(-1) scaling behaviour in the atmospheric boundary layer and its connection to large scale coherent structures within the boundary layer. Wind lidar measurements were conducted above a lake under cold atmospheric con ...

Low-Power Chip-Scale Rubidium Plasma Light Source for Miniature Atomic Clocks

Nico de Rooij, Herbert Shea, Yves Pétremand, Vinu Lalgudi Venkatraman

We present the development, testing and characterization of a low-power chip-scale Rubidium (Rb) plasma light source designed to serve for optical pumping in miniature atomic clocks. The technique used is electrodeless capacitively coupled plasma (CCP) dis ...

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 ...

Brillouin Echoes for Advanced Distributed Sensing in Optical Fibres

Stella Foaleng Mafang

Brillouin scattering is particularly efficient and attractive for the implementation of strain and temperature distributed sensing in optical fibres. Recently a trend has been observed that modern advanced applications require a substantial step towards be ...

Fibers doped with bismuth show broad luminescence bands around 750, 1100, and 1400 nm with spectral bandwidths of 100 to 200 nm at room temperature. The luminescence bands can be observed by pumping broad absorption bands in the visible or near infrared sp ...

Polarization properties of semiconductor quantum dot and dash lasers

Philipp Ridha

Self-assembled quantum-dots (QDs) represent a distributed ensemble of zero dimensional structures, each presenting a near-singular density of states. The QD size, shape, areal density and optical properties depend on growth parameters, such as growth tempe ...
