Abstract: (2034 Views)
The authors propose a novel method for generation of optical Pulse Width Modulation (PWM) based on microfluidic droplet creation through the Mach–Zehnder interferometer (MZI) waveguide. The main parameters for the generation of this PWM such as frequency and speed of switching can be controlled by the mass flow rates of input fluids, and the shape of plug or droplet. The advantages of this design are the reconfigurability in the design, easy control of the fluid behavior, and hence the switching parameters. The validation of the proposed design is carried out by employing the Finite Volume Method" (FVM) for the mechanical simulation and the finite-difference time domain (FDTD) for the optical simulation.
