Patent number: 11815750Abstract: An optical modulator that uses adiabatic tapers to change the width of the waveguides between multimode waveguides and single mode waveguides on a low-loss, e.g. thin-film lithium niobate, electro-optic platform. The architecture enables the utilization of the fundamental mode of multimode wide optical waveguides that have lower optical propagation loss without sacrificing the benefit of the signal integrity and ease of control of single mode operation.Type: GrantFiled: November 22, 2021Date of Patent: November 14, 2023Assignee: HyperLight CorporationInventors: Mian Zhang, Christian Reimer, Kevin Luke

Patent number: 11733586Abstract: An integrated electro-optic frequency comb generator based on ultralow loss integrated, e.g. thin-film lithium niobate, platform, which enables low power consumption comb generation spanning over a wider range of optical frequencies. The comb generator includes an intensity modulator, and at least one phase modulator, which provides a powerful technique to generate a broad high power comb, without using an optical resonator. A compact integrated electro-optic modulator based frequency comb generator, provides the benefits of integrated, e.g. lithium niobate, platform including low waveguide loss, high electro-optic modulation efficiency, small bending radius and flexible microwave design.Type: GrantFiled: March 23, 2022Date of Patent: August 22, 2023Assignee: HyperLight CorporationInventors: Mian Zhang, Christian Reimer, Kevin Luke

Patent number: 11474384Abstract: A velocity mismatch between optical signals and microwave electrical signals in electro-optic devices, such as modulators, may be compensated by utilizing different lengths of bends in the optical waveguides as compared to the microwave electrodes to match the velocity of the microwave signal propagating along the coplanar waveguide to the velocity of the optical signal. To ensure the electrode bends do not affect the light in the optical waveguide bends, the electrode may have to be rerouted, e.g. above or below, the optical waveguide layer. To ensure that the pair of optical waveguides have the same optical length, a waveguide crossing may be used to cross the first waveguide through the second waveguide.Type: GrantFiled: April 2, 2020Date of Patent: October 18, 2022Assignee: HyperLight CorporationInventors: Prashanta Kharel, Mian Zhang, Christian Reimer
