Title: Innovations of Fred Kropf in Electro-Optic Modulation
Introduction
Fred Kropf is an accomplished inventor based in Cranberry Township, PA (US). He has made significant contributions to the field of electro-optic modulation, holding a total of 2 patents. His work focuses on improving the performance and stability of electro-optic modulators through innovative materials and designs.
Latest Patents
Kropf's latest patents include an electro-optic modulator utilizing copper-tungsten electrodes for improved thermal stability. This high-power electro-optic modulator (EOM) employs specialized electrodes made from a material selected to match the coefficient of thermal expansion (CTE) of the modulator's crystal. By ensuring CTE matching, Kropf reduces the presence of stress-induced birefringence, which can cause unwanted modulation of the optical signal. The electrodes are preferably formed from a CuW metal matrix composite, with a W/Cu ratio chosen to achieve the desired CTE value. Additionally, these CuW-based electrodes exhibit thermal conductivity that is about an order of magnitude greater than conventional materials like brass and Kovar, thereby enhancing the thermal stability of the EOM's performance.
