Polarization Maintaining Low-Loss Slotted Core Kagome Lattice THz Fiber

Design of a single‐mode photonic crystal fibre with ultra‐low material loss and large effective mode area in THz regime

“…Till now, large numbers of THz theoretical and practical schemas have been reported by the researchers due to minimising the EML [2,[16][17][18][19][20]. Rana et al [16] proposed a hexagonal-shaped photonic crystal fibre (PCF) where three layers hexagonal core vicinity is surrounded by three layers hexagonal cladding.…”

Low Loss and Low Dispersion Fiber for Transmission Applications in the Terahertz Regime

“…Within the frequency range 0.5-0.9 THz the proposed fiber shows ultralow EML between 0.0103-0.0145cm -1 , which is only between 4.9% and 7.3% of the bulk material loss of the background material. The EML results of this fiber are clearly lower than previously reported values for other designs [14][15][16][17][18][19][20][21][22][23][24][25][26][27]. Investigation of the EML of the terahertz radiation in Fig.…”

“…The proposed fiber exhibits not only low EML but also low dispersion. Slotted fibers with air-cladding [24], [25] circular lattice cladding [26] and kagome cladding [27] were reported earlier.…”

A single mode porous-core square lattice photonic crystal fiber for THz wave propagation

“…Dispersion plays a vital role when it comes to consider in practical implementations. A PCF should show very small dispersion over a wide range of frequencies, which is particularly suitable for transmission of wideband signals [22]. On the contrary, flattened dispersion profile permits transmission of simultaneous signals having approximately same pulse spreading.…”

“…A hexagonal PCF with hexagonal porous-air holes has been proposed in [21], where the reported EML was comparatively higher about 0.12 cm -1 . Very recently, a porous-core kagome lattice PCF has been reported in [22] using hexagonal lattice air-holes in the core. This PCF showed very low EML of 0.035 cm -1 at 1.0 THz.…”
