Title: Innovations of Joseph Katz: Pioneering Far Infrared Radiation Technology

Introduction: Joseph Katz, an inventive mind based in Pasadena, California, holds five patents that reflect his significant contributions to the field of far infrared radiation generation and electro-optic modulation. His innovative work continues to influence technology and research in photonics and materials science.

Latest Patents: Katz's most recent patents showcase his expertise in advancing the generation of tunable far infrared radiation. One notable patent outlines a method for producing tunable far infrared radiation utilizing two-dimensional plasmons in a heterostructure. This innovative approach allows for the generation of large inversion-layer electron densities at the heterointerface, eliminating the need for metallic gratings typically used to couple out radiation. Instead, a unique light interference pattern is created on the heterostructure's planar surface through the interaction of two coherent laser beams, selected to be strongly absorbed by the material. By adjusting the angle between these beams or modifying their wavelengths, Katz enables tuning of the far infrared radiation emitted.

Another significant patent by Katz involves the creation of a monolithic electro-optic modulator array. This patent describes a PIN GaAlAs diode structure designed for light-guiding in single mode. By establishing an index of refraction within the central layer greater than that of the adjoining p- and n-layers, he successfully develops a slab waveguide. This innovation includes stripe contacts that electrically and optically separate waveguide channels, allowing for the application of different reverse biasing voltages for effective light modulation.

Career Highlights: Joseph Katz's career includes remarkable associations with esteemed organizations such as the California Institute of Technology and the United States of America as represented by the Administrator. His background and experiences with these institutions have contributed to his development as a leading inventor in the field of optics and photonics.
