A method and device for modifying the intensity and polarization of radiation in silicon waveguides uses a biasing voltage.

Silicon waveguides have been integral to the field of photonics because they permit miniaturized, power-efficient devices that can manipulate light on a microscopic scale. But traditionally, controlling properties of light, such as its intensity and polarization, has been a difficult task due to the limited means of modification available. Current approaches typically utilize separate systems to control the intensity and the polarization. This approach leads to a greater expense in terms of resources, space, and power. These solutions also lack precision and control, pushing the need for a more efficient, comprehensive way to alter these radiation characteristics concurrently.

Technology Description

This technology pertains to a method and apparatus that modulate both the intensity and the polarization of radiation in silicon waveguides. By applying a biasing voltage to the waveguide, the technology can manipulate these parameters, offering unprecedented control over the properties of propagated light or other types of electromagnetic radiation. The modulation system can be incorporated into any setup requiring adjustable control of radiation parameters, making it versatile across many industries. What sets this technology apart is the ability to alter both the polarization and intensity of radiation concurrently. By using silicon waveguides and applying a specific biasing voltage, the system enables precise control over these radiation parameters. Until now, methods generally only controlled one parameter at a time, meaning this technology brings about enhanced control, flexibility and precision in radiation-based systems.
