Latest Patents
One of DePoy's latest patents is the "Reconfigurable Optical Add/Drop Filter." This optical filter features a resonator cavity made of a saturable absorber material. It includes an input signal waveguide, a non-resonant wavelengths output waveguide, and a resonant wavelength output waveguide that are all coupled to the cavity. The refractive index of the saturable absorber material is adjusted to direct a resonant wavelength output down the resonant wavelength output waveguide while non-resonant wavelengths are directed down the non-resonant wavelengths output waveguide.
Another significant patent is the "Tube-in-Tube Thermophotovoltaic Generator." This device consists of at least one thermal radiator tube and a cooling tube that is concentrically placed within each thermal radiator tube. An array of thermophotovoltaic cells is positioned on the exterior surface of the cooling tube. The design includes a shell that surrounds the thermal radiator tube, with inner and outer tubesheets located at each end of the shell. The configuration allows for multiple thermal radiator tubes to be arranged in either a staggered or in-line formation within the shell.
