Latest Patents

Porter's latest patents focus on a groundbreaking optical fiber communications link. This technology utilizes pulse-width modulation (PWM) encoding to support both synchronous and asynchronous data transmission. The system operates over a wide range of data rates, making it versatile for various applications. The PWM encoder accepts either synchronous (clock plus data) or asynchronous (data only) binary inputs, generating a PWM encoded waveform. This waveform is transmitted through an optical transmitter, optical channel, and optical receiver to a PWM decoder, which reconstructs the binary inputs. The optical receiver is equipped with a circuit that ensures automatic gain control, regardless of the duty cycle. In synchronous mode, the unsymmetrical clock output is restored to symmetry using a clock symmetry restoration technique.
