摘要：

A new porous core PolyEthylene Terephthalate Photonic crystal fiber (PET-PCF) has been proposed that promises to demonstrate substantial optical nonlinearity with the SCG in the near-infrared region. The suggested structure has a diamond-shaped core, which allows for excellent confinement inside the core and aids in achieving an excellent nonlinear coefficient value of 6000 GW(-1) km(-1) and birefringence of the order of 10(-4) at 1550 nm. The proposed material PET is exceptionally lightweight, efficient, shatterproof, and low cost with a very high nonlinear refractive index and simple to fabricate by using the usual stack-and-build process. The PET-PCF becomes a good nonlinear fiber due to the air-polymer combination. Nonlinear signal processing and supercontinuum production will be possible with the suggested fiber.
