Latest Patents
One of her latest patents is titled "Photoreflectance spectral analysis of semiconductor laser structures." This invention involves a micro-photoreflectance technique that allows for non-destructive analysis of III-V optoelectronic devices. By utilizing a significantly reduced spot size, such as 10 micrometers, various compositional features of the device can be analyzed. The patent also discusses the analysis of Franz-Keldysh oscillations in the micro-photoreflectance wavelength spectra, providing valuable information regarding the physical characteristics of the device, including the electric field and p-i junction placement within an exemplary EML device structure.
Another notable patent is the "Method of improving laser yield for target wavelengths in epitaxial." This method focuses on producing a batch of multi-quantum well (MQW) lasers from multiple wafers with varying doping concentrations. The MQW lasers are created by epitaxially growing an InGaAsP quaternary layer on the substrates in a metal-organic chemical vapor deposition (MOCVD) reactor. The process includes segregating the substrates based on doping concentrations and batch producing lasers at specific target wavelengths for each segregated substrate group.
