We present the numerical simulation of an all-optical demultiplexer using 2D photonic crystal ring resonators for optical communications systems. The structure consists of three ring resonators, one bus waveguide, and three drop waveguides. The photonic crystal of the demultiplexer has a square-shaped structure made up of silicon rods with lattice constant a = 548 nm, filling factor(r/a) of 0.18, where r is the radius of the rods, and linear refractive index of n = 3.4. The structure can filter three standard wavelengths with 4.2 nm channel spacing between the wavelengths. From the simulations, the mean quality factor and transmission efficiency of our structure are computed to be respectively 4936 and 96.5%, at wavelengths very close to 1.55 μm. The minimum and maximum values of crosstalk are −18.6 dB and −34.6 dB, respectively. The footprint of the device is 293.7 μm 2 , which is suitable for photonic integrated circuits. The optical characteristics and the behavior of the proposed demultiplexer have been achieved by means of finite-difference time-domain (FDTD) method.

On-chip photonic circuits of different specific functions are highly desirable and becoming significant demands in all-optical communication network. Especially, the function to control the transmission directions of the optical signals in integrated circuits is a fundamental research. Previous schemes, such as on-chip optical circulators, are mostly realized by Faraday effect which suffers from material incompatibilities between semiconductors and magneto-optical materials. Achieving highly functional circuits in which light circulates in a particular direction with satisfied performances are still difficult in pure silicon photonics platform. Here, we propose and experimentally demonstrate a three-port passive device supporting optical ordered-route transmission based on silicon thermo-optic effect for the first time. By injecting strong power from only one port, the light could transmit through the three ports in a strict order (1→2, 2→3, 3→1) while be blocked in the opposite order (1→3, 3→2, 2→1). The blocking extinction ratios and operation bandwidths have been investigated in this paper. Moreover, with compact size, economic fabrication process and great extensibility, this proposed photonic integrated circuit is competitive to be applied in on-chip all-optical information processing systems, such as path priority selector.
