Polarization mode control of long-wavelength VCSELs by intracavity patterning

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

Polarization mode control is enhanced in wafer-fused verticalcavity surface-emitting lasers emitting at 1310 nm wavelength by etching two symmetrically arranged arcs above the gain structure within the laser cavity. The intracavity patterning introduces bi ...

Optical Injection and Lasing Dynamics in Long-Wavelength VCSELs With Intracavity Patterning

Benjamin Dwir, Elyahou Kapon, Alexei Sirbu, Vladimir Iakovlev, Alexandru Mereuta, Andrei Caliman, Zlatko Mickovic, Christopher Michael Long, Dalila Ellafi

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 ...

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

Benjamin Dwir, Elyahou Kapon, Alexei Sirbu, Vladimir Iakovlev, Alexandru Mereuta, 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 ...

Predictability of biomass burning in response to climate changes

Basil Andrew Stansfield Davis, Christopher Michael Long, Yi Zhang

Climate is an important control on biomass burning, but the sensitivity of fire to changes in temperature and moisture balance has not been quantified. We analyze sedimentary charcoal records to show that the changes in fire regime over the past 21,000 yrs ...

Optical injection locking of polarization modes and spatial modes in single-aperture VCSELs and VCSEL arrays emitting at 1.3 mu m

Elyahou Kapon, Alexei Sirbu, Vladimir Iakovlev, Grigore Suruceanu, Alexandru Mereuta, Andrei Caliman, Elodie Lamothe, Christopher Michael Long

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 ...
