Latest Patents

Richard J Black holds a patent for a "Compact wavelength filter integrated to a single-mode optical fiber." This invention involves a wavelength filter that is integrated into a single-mode optical fiber capable of propagating a light signal. The fiber features a longitudinal and opaque outer jacket that envelops it. The jacket is stripped on a specific length to create a non-jacketed section of the optical fiber. This non-jacketed length is formed with first and second concatenated biconical tapers, which are separated by a predetermined distance and each having a specific profile. By carefully selecting the distance between the two tapers and their profiles, the filter allows for the transmission of a first predetermined wavelength of the light signal while blocking a second predetermined wavelength. Additionally, a method for integrating such a filter into a single-mode optical fiber is proposed.
