Latest Patents

One of his latest patents is titled "Vernier effect DBR lasers incorporating integrated tuning elements." This invention discloses a Vernier effect DBR laser that features uniform laser injection current pumping along its length. The design includes one or more tuning elements, separate from the laser injection element, which can control the temperature or modal refractive index of various sections of the laser. This allows for direct control of the refractive indices of each diffraction grating through temperature changes or electro-optic effects, enabling a wider tuning range for the laser. Additionally, the uniform pumping through a single electrode minimizes interfacial reflections, reducing multi-mode operation and mode hopping.

Another significant patent is the "Quantum cascade laser optimized for epitaxial side-down mounting." This invention addresses the challenges of optimizing heat transfer between quantum cascade laser (QCL) chips and their heat sinks. By utilizing a heatsink with high thermal conductivity and minimizing thermal resistance, the design ensures that the active region of the QCL is positioned close to the heatsink. To prevent short-circuiting during the bonding process, the invention proposes a trench around the chip, allowing surplus solder to occupy the space without contacting the chip's sides.
