In this thesis, we studied the modal structure and the polarization of the optical field emitted by vertical-cavity surface-emitting lasers (VCSELs) emitting in the short- and long-wavelength domains (0.9-1.3μm). Our study concerns two types of components: ...

We report the injection locking of specific spatial modes and polarization modes of 1.3 mu m wavelength vertical surface emitting lasers (VCSELs) in single-aperture devices and phase-coupled arrays. The optical injection is realized using a master laser (M ...

Eigenmode analysis of phased-coupled VCSEL arrays using spatial coherence measurements

Elyahou Kapon, Elodie Lamothe, Lars Lundeberg

We apply the modal coherence theory to evaluate the spatial mode structure of a 2 × 2 phase-coupled array of vertical cavity surface emitting lasers (VCSELs). The eigenmode structure is extracted for different pump currents by measuring the degree of spati ...

Spatial transverse modes and polarization states are experimentally studied in single vertical cavity surface emitting lasers (VCSELs) and phased-locked VCSEL arrays emitting at 1.3 mu m wavelength. Analysis of the polarization-resolved near fields, far fi ...

Mode control in wafer-fused 1.3 mu m wavelength coupled-VCSEL arrays is achieved by cavity structuring and investigated by spectrally resolved near- and far-field measurements. Improved mode discrimination is attained by combining index- and gain-patternin ...

Micro-optics for optical trapping in microfluidics - art. no. 66440P

René Salathé, Fabrice Merenda, Johann Rohner, Jean-Marc Fournier, Elodie Lamothe

Micro-optical compo nents offer several possibilities for creating large matrices of optical traps, either when working on inverted microscopes, or by directly integrating miniaturized optical components at the level of a micro-fluidic chip. In thisarticle ...

We study the forces generated by an electromagnetic field on two coupled gold nanowires at the vicinity of the plasmon resonance wavelength. Two different regimes are observed, depending on the separation distance d between the wires. In the near field cou ...
