Latest Patents

One of Juejun Hu's notable patents is for an ultra-low-energy non-volatile phase shifter. This integrated photonic device includes a waveguide that allows radiation to propagate through it. The phase shifter is optically coupled to the waveguide and comprises a heat-actuable phase change material (PCM). A heater, which has a layer of a two-dimensional material, is in thermal communication with the PCM. This configuration enables the heater to receive a reset voltage pulse, causing the graphene layer to heat and cool. The thermal communication results in a phase transition of the PCM, altering its refractive index and producing a phase shift in the radiation traveling through the waveguide.
