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

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