Abstract

We propose an optofluidic based on two dimensional (2D) rod-type silicon photonic crystal (PhC) waveguide that support self-collimation effect over a large frequency and angle range without any defect or nano-scale variation in the PhC geometry. By analyzing the Equi-Frequency contour (EFC) of a triangular rod PhC-bands, we verify the optimum band of the structure that is suitable for self-collimation of light beams. By varying the refractive index of fluid which is being infiltrated into the background of PhC, we perform a systematic study of optofluidic self-collimation of light beams to achieve a wide range of angles and low loss of light. By means of selective microfluidic infiltration, and remarkable dispersion properties we show it is possible to design, auto-collimator, and negative refraction devices based on self-collimation effect with high transmission. We use the plane wave method (PWM) for analyzing the EFC and the finite difference time domain (FDTD) method for simulating the transmission properties.
