Silicon (Silicon Photonics and Planar Lightwave Circuits): Silicon is very inefficient in generating or detecting light in the telecom wavelength window as it is an indirect bandgap semiconductor material. Consequently, waveguides of silicon or doped silicon dioxide (silica) exhibit very low optical loss and are ideal for switching, filtering, or interferometric appliions.
