Title: Innovations by Lee Lisheng Huang
Introduction
Lee Lisheng Huang is an accomplished inventor based in Sunnyvale, CA (US). He holds a total of 5 patents that showcase his expertise in optical technologies. His work has significantly contributed to advancements in the field of thermo-optic switches and variable optical attenuators.
Latest Patents
One of his latest patents is a thermo-optic switch having a fast rise-time. This innovative switch operates in a novel near-impulse mode, where the drive pulse width is shorter than twice the diffusion time of the switch. The design allows for a drive pulse width that is less than the rise time of the steady-state optical response, enabling faster operation. Additionally, the switch can maintain an ON state for extended periods through a sustaining segment. This technology can be utilized in an array of thermo-optic switches to create displays with rapid refresh rates.
Another significant patent is the variable optical attenuator. This device utilizes randomly polarized light that impinges upon a birefringent crystal, splitting it into orthogonal polarization components. The light then passes through polarization rotators that adjust the plane of polarization. The variable rotator responds to an external control signal, allowing for a maximum operating range of 0 to 100% attenuation. The design includes a second birefringent crystal and wave plates to ensure precise control over light intensity.
