Latest Patents

Dave Walker holds a patent for "Optical E-field modulation using a directly driven laser." This patent describes a method of synthesizing a modulated optical signal using a laser cascaded with an amplitude modulator. The process involves deriving a phase drive signal V(t) to drive the laser, generating an optical carrier signal with a desired phase φ(t). Additionally, an amplitude drive signal V(t) is derived to impose a desired amplitude S(t) onto the optical carrier signal. The amplitude drive signal is compensated for amplitude modulation of the optical carrier signal generated by the laser. This innovative approach enhances the efficiency and effectiveness of optical signal modulation.
