Latest Patents

Wasiak holds a patent for a "Vertical cavity surface emitting laser cavity with low thermal impedance." This invention introduces new designs of VCLs that incorporate high contrast gratings (HCG) combined with a diamond layer as a bottom mirror. The designs can be realized using a classical V-shaped pumping scenario or by introducing the pumping beam from the bottom direction through the HCG, which can be designed to be transparent at the wavelength of the pumping light. Additionally, the invention can be completed with an HCG combined with a diamond layer as a top mirror, reflecting the pump diode laser while remaining transparent to the VCL emission when the pumped and emitted beams are collinear.
