Latest Patents

Shane Duggan holds a patent for a "Phase modulator for optical signal using multimode interference couplers." This invention provides an optical system and method for outputting a modulated signal using a single multimode interference (MMI) device. The device has at least two inputs configured with a fixed phase and an output. The output modulated signal is controlled by modulating the input power of at least one of the inputs. This invention simplifies the process by requiring only a single MMI device to operate, as the relative phase between the two inputs is fixed. One of the inputs can modulate the output by adjusting the power at a single input. Further embodiments demonstrate how correct phases can be set by a single MMI device, eliminating the need for more than two MMIs in conjunction with phase or amplitude modulating elements to generate BPSK or QPSK signals.
