Latest Patents
One of Patrick Callahan's notable patents is titled "Athermal angular output by combining a laser with a grating based antenna." This patent describes an internal laser component of an optical device that includes a waveguide defining a guided mode of a first optical wave. This wave is characterized by a first propagation constant associated with a first effective refractive index. Additionally, the optical antenna grating comprises a waveguide that defines a guided mode of a second optical wave, characterized by a second propagation constant associated with a second effective refractive index. The grating structure is designed to emit a portion of the second optical wave in a selected direction. The relationship between the first and second effective refractive indices ensures that the selected direction remains substantially insensitive to temperature changes in the thermal environment where the components are thermally coupled. This innovation has the potential to enhance the performance of optical devices in varying conditions.
