Latest Patents

One of his latest patents involves spectroscopy systems and methods using quantum cascade laser arrays with lenses. This innovative system includes an array of quantum cascade lasers (QCLs) that emit non-coincident laser beams. A lens array coupled to the QCL array collimates these beams, allowing them to propagate along parallel optical axes towards a sample. The design ensures that the beams remain collimated over the lens array's working distance, providing precise measurements of the sample's absorption or emission spectrum.

Another notable patent focuses on methods for forming photonic integrated circuits based on quantum cascade structures. This technology utilizes a QC layer in a wave confinement region of an integrated multi-layer semiconductor structure capable of producing optical gain. By depleting free charge carriers, Diehl's methods create low-loss optical wave confinement regions, overcoming challenges related to high costs and complex fabrication processes.
