Latest Patents

Gopalakrishnan's latest patents include an optical modulator for CATV systems. This resonantly enhanced external electro-optic modulator reduces the required drive power. The modulator features a coupling structure that efficiently transfers power from a feed line into the resonator, eliminating the need for a terminal impedance. It can be driven by an RF signal designed to suppress Stimulated Brillouin Scattering (SBS) in long-haul, high-power fiber optic links, which are essential for transmitting analog CATV signals. Additionally, the modulator can depolarize an optical signal.

Another significant patent involves the cancellation of distortion components in a fiber optic link. This phase modulator is utilized in an externally modulated, feed-forward linearized analog CATV link to reduce fiber-induced composite second order (CSO) distortion components. The system is compatible with existing commercially available modulators and addresses the challenges posed by self-phase modulation in fiber optic links.
