With a total of six patents to his name, Fritz has focused on developing advanced light-emitting diodes and optical modulators that have various applications in modern technology.

Latest Patents

One of Fritz's latest patents is for a broadband light-emitting diode. This innovative LED comprises a plurality of III-V compound semiconductor layers grown on a semiconductor substrate. The design includes a pair of cladding layers surrounding a strained-quantum-well active region, which has multiple energy bandgaps for generating light in a wavelength range of about 1.3-2 micrometers. In one embodiment, the active region features oppositely strained quantum-well layers, while another embodiment utilizes a short-period superlattice structure made of alternating thin layers of InGaAs and InGaAlAs. This structure allows for precise growth by repetitively switching between different growth states in an MBE growth apparatus. The broadband LED can be configured as either a surface-emitting or edge-emitting device, suitable for applications such as chemical sensing, fiber optic gyroscopes, and wavelength-division-multiplexed fiber-optic data links.

Another significant patent by Fritz is the tandem resonator reflectance modulator. This device is designed as tandem Fabry-Perot resonators, which include three mirrors spaced by two cavities. The absorption characteristics of one cavity can be altered relative to the other by applying an electric field, resulting in a change in the total reflected light. This innovative approach allows for enhanced control over light reflection, making it a valuable tool in optical applications.
