Vertical cavity surface emitting laser cavity with low thermal impedance

Elyahou Kapon, Vladimir Iakovlev, Pascal Gallo

The present invention concerns new designs of VCLs with high contrast gratings (HCG) combined with diamond layer as a bottom mirror. They can be realized either with a classical V-shaped pumping scenario, or through the introduction of the pumping beam fro ...

Recent progress in wafer-fused VECSELs emitting in the 1310nm and 1550nm bands

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

Recent developments of wafer-fused long-wavelength VECSELs resulted in reaching record high CW output power of 6.6 W at 1300 nm and a coherence length longer than 5 km in fiber and 1 Watt of output power in single frequency regime at 1550 nm. First wafer-f ...

Reliability of 1310 nm Wafer Fused VCSELs

Elyahou Kapon, Grigore Suruceanu, Alexandru Mereuta, Vladimir Iakovlev, Alexei Sirbu, Andrei Caliman, Zlatko Mickovic

Wafer fusion vertical cavity surface emitting laser (VCSEL) technology has produced devices that successfully passed all mechanical and electrical Telcordia qualification tests. Accelerated lifetime tests result in times to 1% failure at 70 degrees C of 18 ...

14XX nm-wavelength electrically-pumped VECSELs fabricated by wafer fusion

Elyahou Kapon, Alexandru Mereuta, Vladimir Iakovlev, Alexei Sirbu, Andrei Caliman, Kamil Pawel Pierscinski

We report on the design, fabrication and characterization of electrically pumped vertical external cavity surface emitting lasers (EP-VECSELs) emitting at 1470 nm. We demonstrate 6.2 mW of CW output power, which represents the highest power value reported ...

Transverse mode discrimination in long-wavelength wafer-fused vertical-cavity surface-emitting lasers by intra-cavity patterning

Elyahou Kapon, Benjamin Dwir, Nicolas Volet, Alexandru Mereuta, Vladimir Iakovlev, Alexei Sirbu, Andrei Caliman, Pascal Gallo, Zlatko Mickovic, Lukas Mutter

Transverse mode discrimination is demonstrated in long-wavelength wafer-fused vertical-cavity surface-emitting lasers using ring-shaped air gap patterns at the fused interface between the cavity and the top distributed Bragg reflector. A significant number ...

Spatial-Mode Discrimination in Guided and Antiguided Arrays of Long-Wavelength VCSELs

Elyahou Kapon, Nicolas Volet, Vladimir Iakovlev

Three means of optical confinement imposed on InAlGaAs/InP 1.3 mu m VCSEL arrays are investigated with self-consistent numerical model of laser operation. Laterally patterned tunnel junction (TJ), in-build guiding realized with air-gap patterning, and anti ...

Polarization mode structure in long-wavelength wafer-fused vertical-cavity surface-emitting lasers

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

Applications of long-wavelength (lambda > 1 mu m) vertical-cavity surface-emitting lasers (VCSELs) generally require close control over wavelength and polarization of the emitted light. In most cases, single mode and polarization stable lasing is desired. ...
