“…The photonic bandgap changes with the refractive index, temperature, and angle of incidence of the beam [14,15]. Consequently, this physical phenomenon allows us to design photonic crystal-based optical sensors to detect changes in the refractive index [16][17][18][19][20][21][22] and temperature [23,24]. Recently, photonic crystals have gained the courtesy of researchers for their exclusive properties, making them suitable for use in various applications such as omnidirectional reflectors [25][26][27][28][29][30], filters [31][32][33], and very sensitive sensors in the field of optics [34].…”

We report on simulated temperature-tunable single-channel/multichannel transmission filters in the infrared region (1300 nanometers -1650 nanometers) using a one-dimensional photonic crystal structure. A single channel can be selected in the photonic bandgap region based on the thickness of the quarter-wave stacks and temperature. The transmission coefficient of the transmitted defect modes is approximately the same as that required for telecommunication. For 20000 defect layers, 600 channels were created with full width at half maximum of 0.7 picometers at the center wavelength of ~ 1550 nm and channel separation of ~0.18 nanometer between 1500 nanometers-1600 nanometers.

“…In latest foregone time, negative refraction (NR) and negative index material (NIM) or left-handed material (LHM) in a low wavelength region gained mammoth attention in having a vision of their application in the design and development of photonic devices at nanoscale [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. However, in the infra-red region nanoscale, split ring resonator (SRR) structures showed astonishing results.…”

“…Even so, SRR endured with the saturation limit of a resonant magnetic response with negative effective permeability at high frequencies [14]. Subsequently, substitute strategies to design and develop contemporary materials baring NR have been of great interest of researchers [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Ad-ditionally, striking advancement has been recently made toward shrinking the size of optical devices.…”

In present paper, a tunable left-handed plasmonic nanoantenna is designed to attain ultraviolet emission through a second harmonic generation with a phase harmonic condition. For the devised structure, the dispersion properties and negative values of the magnetic permeability and the electric permittivity show that the designed structure is left-handed for the primary wave (red light) and right-handed for the second harmonic wave (ultraviolet light). The 3D finite-difference time-domain method is employed to reveal its nonpareil skills (i.e. immense left-handed transmission efficiency and far-field spectrum exhibiting directionality). Attained results by numerical calculation for the second harmonic generation are accomplished with finite-difference time-domain analysis. The impact of physical parameters on transmission and dispersion characteristics is also scrutinized. Furthermore, flat lens application for a red light region with a centered wavelength at λ = 650 nm from the guileless design of LHM with no aberration is triumphed. Ultimately, a multifunction left-handed material is designed revealing tremendous potential to amass and abridge future applications in one architecture.

“…Any change in refractive index, temperature, or angle of incidence will change the photonic band gap. This is the rule of operation of a photonic crystal when acting as an optical sensor for detection variations in the index of refraction [5][6][7][8][9][10][11] and temperature [12,13].…”

Recently, one-dimensional periodic ternary photonic crystals have shown outstanding properties when compared to onedimensional periodic binary photonic crystals. In this work, a ternary photonic crystal is proposed as a temperature sensor. The structure of the ternary photonic structure is considered Si/polymer/SiO 2. The transmission spectra of the proposed ternary photonic structure are studied for different temperatures. It is observed that as the temperature increases, the transmission peak shifts toward higher wavelengths due to thermo-optic and thermal expansion coefficients of the polymer. It is found that the temperature-sensitive transmission peak shift is considerably enhanced due to the insertion of the polymer layer between Si and SiO 2 to constitute a ternary photonic crystal.
