Abstract:

Soon many integrated microelectronic devices could be replaced by the integrated silicon photonic chips. The silicon photonics devices and systems are the next technological development that will significantly impact our everyday function the same way that integrated microelectronics did in early 1960s. Just like the microelectronics, interconnects and inputs/outputs are important challenges for the high-density integrated silicon photonics circuits. In this talk we discuss the evanescent light coupling into the crystalline silicon waveguides using a dielectric prism and surface plasmon polaritons. However, contrary to the standard prism-coupling, our prism has a smaller index of refraction than the Si waveguide for the telecomm wavelength range. This coupling method is modeled numerically to simulate light-metal-silicon interaction. We will demonstrate an example device that is fabricated with the standard cleanroom technologies on a silicon-oninsulator wafer
