Silicon photonic waveguide structures and devices: From fundamentals to implementations in spectroscopy and biological sensing

In this chapter we discuss recent advances in silicon photonics research at the National Research Council Canada. We review our work on first implementations of subwavelength grating structures in silicon waveguides, including efficient fiber-chip coupling structures, and anti-reflective and high-reflectivity structures formed at the SOI waveguide facets. Silicon planar waveguide spectrometer chips are introduced, namely a high-resolution …
