“…These components have been designed and fabricated using PhC [2][3][4][5][6][7][8][9][10], including direct splitting, such as Y-junctions [2][3][4][5] and T-junctions [6], and directional couplers [7,8]. Multimode interference (MMI) based on the self-imaging principle, is also widely adopted [7][8][9][10].…”

“…A device based on the MMI effect in PhC can be much smaller than a conventional MMI device due to the large dispersion of a PhC structure. PhC-based MMI structures have been successfully used in, e.g., power splitters [14], optical switches [15], and demultiplexers [16]. To realize a multimode PhC waveguide based PBS, both transverse-electric (TE) and transverse-magnetic (TM) polarized light must propagate with low loss in the PhC structure.…”

Abstract-We present the design and simulation of an ultra-compact polarization beam splitter (PBS) by combining a photonic crystal (PhC) multimode waveguide and an internal PhC section. The PhC multimode waveguide is designed to collect the powers reflected by or transmitted through the internal PhC structure which serves as a polarization sensitive scatterer. Plane wave expansion (PWE) method is used to calculate the band structure and the finite-difference timedomain (FDTD) method is employed to obtain the spectrum response. The simulation results show that the present design can give an ultracompact PBS with high extinction ratio over a broad bandwidth.

“…Beam splitters are one of the central building blocks among the integrated components in PICs. These have been made by slab PhC [3][4][5][6][7][8][9][10][11], including Y-junctions [9][10][11], T-junctions [5,6] and directional couplers [3,4]. Until now, most of the work has focused on the performance of single-mode PhCW, but introducing multi-mode interference regions in the PhCWs provides new extraordinary characteristics [12] and some 1x2 components that use multimode interference have been proposed [7,8].…”

“…Several components have been investigated theoretically including: a wavelength de-multiplexer based on self-imaging phenomena in PhCWs [13], the operation of a terahertz switch based on the self-imaging principle in silicon triangular PhCW [7,14], TE and TM polarization splitters based on the simulation using selfimaging phenomena in PhCW [15] and a 1x2 splitter based on self-imaging phenomena in PhCWs [8]. The 2D simulation of Yu et al [4,16] indicated that the self-imaging phenomena also occurs in PhCWs between every second line defect in devices with many defect lines allowing the realization of 1xN (N≥2) splitters.…”

Based on inspiration from multi-mode interference self-imaging and theoretical FDTD simulations, a 1x3 beam splitter was designed, fabricated and characterized. Measurements show that for TE-polarized incident light the power is distributed equally between the output ports within 1dB in the range from 1541nm to 1552nm, and the total transmission of the 1x3 splitter is equal to the corresponding length of a single-linedefect PhCW within the measurement uncertainty.
