We present the static and optical injection response of wafer-fused long-wavelength VCSELs with and without intracavity patterning. It is found that the extra optical cavity patterning increases the gain anisotropy between orthogonal polarization modes, in ...

Electrically Pumped Vertical-External-Cavity Surface-Emitting Lasers With Patterned Tunnel Junction for Single Transversal-Mode Emission

Elyahou Kapon, Alexei Sirbu

This paper reports on a numerical analysis of methods for current injection into AlInGaAs/InP tunnel-junction electrically pumped vertical-external-cavity surface-emitting lasers. The tunnel junction is patterned to minimize the current crowding effect and ...

The III-nitride semiconductor material system - (InAlGa)N - is of highest interest for optoelectronic applications due to its direct bandgap, tunable from the ultraviolet to the infrared spectral range. The most well-known are white light-emitting diodes, ...

Analysis of structurally sensitive loss in GaN-based VCSEL cavities and its effect on modal discrimination

Nicolas Grandjean, Gatien Cosendey, Ehsan Hashemi

Lateral loss causes optical energy to leave the laser cavity in the transverse, lateral, direction, and is sometimes neglected to simplify the numerical simulations. However, in contrast to outcoupling and absorption losses, we show that the lateral loss c ...

Optical injection locking of transverse modes in 1.3-mu m wavelength coupled-VCSEL arrays

Elyahou Kapon, Benjamin Dwir, Alexandru Mereuta, Vladimir Iakovlev, Alexei Sirbu, Andrei Caliman, Lukas Mutter, Christopher Michael Long

Optical injection locking of 1.3-mu m phase-locked VCSEL arrays defined by patterned tunnel junctions and wafer fusion is investigated experimentally and theoretically. The impact of the overlap between the master laser injection beam and the injected mode ...

Integrated VCSEL-Microlens Scanner With Large Scan Range

Niels Quack

We present an integrated beam steering system with a microlens scanner and a vertical cavity surface-emitting laser (VCSEL) source. The scanner and the VCSEL are assembled with an alignment sphere process and with an accuracy of 121 ±7 μm defined by precis ...

High performance wafer-fused semiconductor disk lasers emitting in the 1300 nm waveband

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

We report for the first time on the performance of 1300 nm waveband semiconductor disc lasers (SDLs) with wafer fused gain mirrors that implement intracavity diamond and flip-chip heat dissipation schemes based on the same gain material. With a new type of ...

Analysis and Control of Optical Modes in VCSELs and VCSEL-Arrays

Elodie Lamothe

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: ...
