Latest Patents

One of his latest patents is titled "Optical broadband emitters and methods of making the same." This patent describes an optical broadband emitter and the method of creating such an emitter. It involves the intermixing of closely coupled multiple quantum wells, particularly carrier tunneled coupled quantum wells. The process utilizes nano-imprinting of a gel-like dielectric layer, such as a sol-gel derived SiO layer, into multiple stepped or graded sections to form intermixing cap regions of varying thickness. A thermal annealing process is then performed to condense the SiO intermixing cap and induce intermixing. Additionally, a superluminescent diode is described, featuring multiple electrodes deposited over sections with different bandgaps. Each electrode can be individually biased, allowing each diode section to function as a spontaneous emitter, amplifier, attenuator, photon-absorber, transparent waveguide, or photodetector.

Another significant patent is for a "Method for quantum well intermixing using pre-annealing enhanced defects diffusion." This process shifts the bandgap energy of a quantum well layer, such as a III-V semiconductor quantum well layer, without inducing complex crystal defects or generating significant free carriers. The method involves introducing ions into a quantum well structure at elevated temperatures, followed by a pre-annealing step that diffuses point defects closer to the quantum well layer. Finally, the structure undergoes thermal annealing at a higher temperature to induce quantum well intermixing, effectively shifting the bandgap energy.
