“…Each band is degenerate because of the high symmetry of waveguide. To create a photonic CT lattice, the hopping term t 2 can be blocked by introducing air holes [28] which decrease the overlap of evanescent wave [FIG. 3(b)].…”

The Kagome bands hosting exotic quantum phases are generally and understandably pertained only to a Kagome lattice. This has severely hampered the research of Kagome physics due to the lack of real Kagome-lattice materials.Interestingly we discover that a coloring-triangle (CT) lattice, named after color-triangle tiling, hosts also Kagome bands. We demonstrate first theoretically the equivalency between the Kagome and CT lattice, and then computationally in photonic (waveguide lattice) and electronic (Au overlayer on electride Ca 2 N surface) systems by respective finite-element and first-principles calculations. The theory can be generalized to even distorted Kagome and CT lattices to exhibit ideal Kagome bands. Our findings open a new avenue to explore the alluding Kagome physics.

“…Most works focused on PCRR structures based on PhCs of dielectric rods and only theoretical simulations. Experimental demonstration of a PCRR based on a PhC of air holes was recently reported by Ren et al [15]. However, the Q factor of their reported PCRR was only 300.…”

A design for enhancing the quality (Q) factor of a photonic crystal ring resonator (PCRR) is introduced. The highest Q factor based on simulations is 121,000. The analysis of momentum space distributions of the electric field profile for PCRR resonance shows that a high Q factor of a PCRR is attributed to the reduction of tangential k-vector component inside the leaky region. A high Q factor of 75,200 is experimentally demonstrated for a modified PCRR on a silicon-on-insulator wafer. The high-Q-factor PCRR demonstrated here will be beneficial for channel drop filters, lasers, sensors, and other applications.

“…It has been observed that photonic crystal cavities a few micrometers in size feature excellent characteristics, including low loss, good confinement, and high quality factor, making them excellent filters [ 12 , 13 ]. Photonic crystal ring resonators can be utilized to create optical switches, optical sensors, optical demultiplexers, and ring laser cavities [ 4 , 14 , 15 , 16 , 17 ]. Dideban et al [ 18 ] developed a channel drop filter in a photonic crystal composed of a hexagonal array of circular air rings.…”

This paper investigates the use of a miniaturized filter based on a triangular lattice of holes in a photonic crystal (PhC) slab. The plane wave expansion method (PWE) and finite-difference time-domain (FDTD) techniques were utilized to analyze the dispersion and transmission spectrum, as well as the quality factor and free spectral range (FSR) of the filter. A 3D simulation has demonstrated that for the designed filter, an FSR of more than 550 nm and a quality factor of 873 can be attained by adiabatically coupling light from a slab waveguide into a PhC waveguide. This work designs a filter structure that is implemented into the waveguide and is suitable for a fully integrated sensor. The small size of the device provides a strong potential for the realization of large arrays of independent filters on a single chip. The fully integrated character of this filter has further advantages such as reducing power loss in coupling light from sources to filters and also from filters to waveguides. The ease of fabrication is another benefit of completely integrating the filter.
