Latest Patents

Hoffman's latest patents include an "Integrated Photonics with Active Polarization Control." This invention describes a polarization controller that converts an input optical signal with a TE mode into an output optical signal with any polarization on the Poincare sphere. The process involves splitting the input signal into two optical signals, where the first retains its TE mode, and the second is transformed into a TM mode. The independent control of the magnitude and phase of these signals allows for versatile polarization output.

Another significant patent is the "Optical Coupler for Heterogeneous Integration." This invention details an optical apparatus where a semiconductor device is heterointegrated on a silicon-based platform. A polymeric waveguide is optically coupled to the semiconductor device, functioning as a multimode interference coupler. The design of the waveguide is tapered to enhance optical coupling efficiency.
