Latest Patents

Shafiiha’s recent patent work addresses light sensing and optical-device connections.

- **Enhancing the Performance of Light Sensors That Receive Light Signals from an Integrated Waveguide.** This invention positions a light sensor and waveguide on a base so the sensor can receive a signal guided by the waveguide. A tapered section is designed with a width ratio greater than 1.2:1 between two locations, while the taper’s length between those locations is less than 60 micrometers.

- **Edge Coupling of Optical Devices.** This invention describes optical modules with separate bases and waveguides aligned to exchange light signals. At least part of one aligned waveguide lies between the modules’ bases. Electronics operate a transmitter on one module and a receiver on another, which produces an electrical signal when the receiver detects the light.
