Latest Patents

One of Glew's latest patents is titled "Net strain reduction in integrated laser-modulator." This patent describes a semiconductor device that includes first and second epitaxial layers grown in a selective area growth region on a substrate. The device features an active layer or well layer comprising a first composition formed using a trimethylgallium precursor material, along with a barrier layer made from a second composition using a triethylgallium precursor material. This innovative approach maximizes the strain in the well layer while minimizing the net strain of the selective area growth region.

Another significant patent by Glew is the "Method for making multiple wavelength semiconductor lasers on a single substrate." This invention involves fabricating a plurality of different wavelength semiconductor lasers on a single semiconductor substrate by establishing a thermal gradient across the substrate during epitaxial growth. The thermal gradient is achieved by disposing a patterned layer of material on the backside of the substrate, which is then heated to create a variation in composition that produces a corresponding variation of laser wavelength across the substrate.
