Latest Patents

Sandra H Withers holds 1 patent for her invention titled "Analog pulse position modulation in harmonically mode-locked lasers." This patent describes a method for analog pulse position modulation of pulsed emission from a laser that is actively and harmonically mode-locked. The invention requires a body of an active gain medium, means for changing the gain as a function of a controllable parameter, and the ability to harmonically and actively mode-lock the laser through fast periodic changes of said parameter. Additionally, it involves superimposing slower changes on the parameter, allowing for continuous shifting between the peak and shoulder of the gain-vs-parameter curve. The proof of concept demonstrates electric control of the separation between two interleaved pulse trains from a far-infrared (1.5-4 THz) p-Ge laser, which is actively mode-locked by RF gain modulation at the second harmonic of the roundtrip frequency. A suggested application for this technology is telemetry using analog pulse position modulation.
