Design of Passive Silicon Photonic Devices

In this chapter, we introduce design principles of essential building blocks of passive silicon photonics, including fiber-to-chip couplers, waveguides, directional couplers, and multimode interferometers. Then, we discuss functional passive devices that operate in wavelength, polarization, and mode dimensions. They cover an arrayed waveguide grating, a micro-ring resonator, a mode converter, a mode (de)multiplexer, multimode bend and crossing, a polarization beam splitter, a polarization rotator, and a polarization splitter and rotator.
