Short-Cavity Integrated VECSELs: A Fabrication Approach
نویسنده
چکیده
We outline the fabrication of an electrically pumped surface-emitting laser with a short vertical extended cavity (VECSEL) for sensing applications. The emission wavelength is detuned by introducing microparticles into the cavity via a microfluidic channel. Multiple longitudinal modes can fit inside the resonator. A reproducible detuning of the extended cavity demands a longitudinal mode spacing of at least a few nanometers. The related resonator length of 80μm therefore requires a tailored fabrication and mounting procedure.

A Fabrication Approach for Hybrid-Integrated Electrically Pumped VECSELs
Unlike a vertical-cavity surface-emitting laser (VCSEL), which comprises two highly reflecting distributed Bragg reflectors (DBRs), the extended cavity in VECSELs employs a third mirror. The fabrication of such a device requires a long process chain, including the patterning of the VCSEL structures, definition of the extended optical resonator, mirror coating and die bonding. While VCSELs have ...
