In order to solve the problems of high performance and small size incompatibility, as well as limited bandwidth, of traditional polarization filters in optical communication systems, this work presents an all-fiber polarization filter using dual elliptical gold layer deposited photonic crystal fiber by the finite element tool. The gold layers are plated on the inside of the two elliptical holes to create surface plasmon resonance effect, which cause the signal intensity in x-polarized direction to be much greater than that in y-polarized direction. The simulation results illustrate that when hole-to-hole pitch Ʌ is 2.0 μm, cladding hole diameter d1 is 2.0 μm, two inner-holes’ diameter d2 is 0.3 μm, spacing between two inner-holes ds is 0.755 μm, the major axis length of elliptical holes a is 2.0 μm, the minor axis length of elliptical holes b is 0.97 μm, the gold thin layer t is 100 nm, the proposed PCF filter exhibits good filtering performance at the communication wavelength of 1.55 μm, where the confinement loss in x- and y-polarized direction are 303.91 dB/cm and 0.06 dB/cm, respectively. The crosstalk and operating bandwidth improve with the increment of device’s length, the 800 μm-long PCF filter possesses the maximum crosstalk of -211.14 dB and the bandwidth of 600 nm. Finally, the experimental scheme is also discussed. We believe that this photonic filter can play a significant role in optical communication, optical sensing, spectral analysis, and other related fields.

The supercontinuum spectrum is generated through a wide range of wavelengths by sending a short and strong pulse to the nonlinear medium and sputtering at the output and is used in optical measurements, spectroscopy, biological imaging optical coherence photography, etc. Integrated photonics is an idea to realize low-cost and microscale communication, sensing, and fast computing methods. In addition, the miniaturization and integration of photonic structures make possible new designs and applications that are inaccessible in their large volumes. Lithium niobate is one of the most widely used and attractive materials in the field of photonics due to its extraordinary electro-optical, acoustic-optical, nonlinear optics, wide transparency window, and relatively high refractive index. In this work, a lithium niobate waveguide is designed by choosing basic solitons as the input pulse and considering various effects such as high-order scattering, self-phase modulation, second harmonic generation, Raman effect, self-downward effect, etc. The proposed waveguide has super-sustainable production. This supercontinuum spectrum is designed in the waveguide, for the 10th order bright soliton at a distance of 35 mm, 4 times the initial width, for the 20th order bright soliton at 9 mm, 4 times the initial width, and for the 30th order bright soliton at 4.5 mm, 5 times the initial pulse width in the frequency domain are created. Such dimensions are suitable for use in photonic integrated circuits.
