“…Although the peak wavelength of reflection (λ max ) in BBCPs can be readily tuned by backbone degree of polymerization, the bandwidths of these materials are somewhat large and broaden with increasing λ max . Better control of bandwidths in these photonic crystals is desirable for some applications . Furthermore, for practical fabrication of BBCP photonic crystals, alternative self‐assembly methods may be required.…”

“…A requirement for practical applications of photonic crystals is that their bandwidths and center frequencies must be well controlled. Filters and resonant cavities require narrow broadband reflections . In contrast, for coatings that prevent absorption and thermalization of solar energy, broadband reflection (several hundred nanometers) of infrared (IR) radiation is often desired .…”

Brush block copolymers are a class of comb polymers that feature polymeric side chains densely grafted to a linear backbone. These polymers display interesting properties due to their dense functionality, low entanglement, and ability to rapidly self‐assemble to highly ordered nanostructures. The ability to prepare brush polymers with precise structures has been enabled by advancements in controlled polymerization techniques. This Feature Article highlights the development of brush block copolymers as photonic crystals that can reflect visible to near‐infrared wavelengths of light. Fabrication of these materials relies on polymer self‐assembly processes to achieve nanoscale ordering, which allows for the rapid preparation of photonic crystals from common organic chemical feedstocks. The characteristic physical properties of brush block copolymers are discussed, along with methods for their preparation. Strategies to induce self‐assembly at ambient temperatures and the use of blending techniques to tune photonic properties are emphasized.

“…One can see PCE at this wavelength is approximately 99% and Δλ is 0.8 nm. Consequently, QF is obtained 1937 that is suitable in comparison with other works based on PCRR [16]- [22] as given in Table 2. Figure 4a demonstrates the ring resonator drops incoming light at wavelength 1550nm to the lower waveguide, while it don't at wavelength 1560nm (Fig.…”

In this paper, a channel drop ring resonator filter based on two dimensional photonic crystal is proposed which is suitable for all optical communication systems. The multilayer of silicon rods in the center of resonant ring enables one to adjust resonant wavelength of the ring and enhance power coupling efficiency between ring and waveguide. Refractive index and radius of multilayer rods inside the ring are important factors which help one to enhance the desired output parameters. The proposed structure is capable of presenting high quality factor near 1937 in conjunction with 0.8 nm pass band. The high coupling efficiency 99% is another advantage of the proposed filter.

“…The behavior of light in PhCs is very similar to that of electrons in semiconductors, so like semiconductors these artificial structures have a forbidden frequency (or wavelength) area for the propagation of light waves which is called Photonic Band Gap (PBG) [1,2]. This property solved the challenge of confining light waves inside PhC structures, therefore designing optical devices such as optical filters [3][4][5][6][7][8][9], optical demultiplexers [10,11] and optical switches and logic gates [12][13][14][15][16][17][18][19][20][21] with ultra-compact dimensions suitable for all optical integrated circuits became possible.…”
