His contributions have significantly impacted the development of efficient laser systems and bipolar transistors.
Latest Patents
One of Krumm's latest patents is for a Vertical Cavity Surface Emitting Laser (VCSEL) and related method. This invention features a design that minimizes vertical resistance between the Ohmic contact and the active layer, allowing for a more efficient and single-mode output. The VCSEL includes a substrate, a lower distributed Bragg reflector (DBR), an active layer, and an upper DBR with a groove that houses the Ohmic contact. This innovative structure confines current flow to the laser cavity, enhancing performance.
Another notable patent involves a structure and method in a Heterojunction Bipolar Transistor (HBT) for an emitter ballast resistor with improved characteristics. This design comprises an emitter cap with multiple layers, including high-doped and low-doped layers, which work together to create an emitter ballast resistor. The low-doped layer's thickness and dopant concentration are optimized to ensure that its resistance remains stable, independent of the dopant concentration.
