A waveguide is a structure that guides waves, such as electromagnetic waves or sound, with minimal loss of energy by restricting the transmission of energy to one direction. Without the physical constraint of a waveguide, wave intensities decrease according to the inverse square law as they expand into three-dimensional space. There are different types of waveguides for different types of waves. The original and most com… WebOther studies of high transmission couplers for PC waveguides [2, 3] have chosen to use linear taper walls, and slant the photonic crystal structure to fol- low the taper walls. ...
