Mid-infrared channel waveguides in RbPb 2 Cl 5 crystal inscribed by femtosecond laser pulses

Abstract: Tubular cladding waveguide was inscribed in crystal volume by a femtosecond laser operating at 0.8 µm. The waveguide sustains a single leaking mode at wavelength of 3.39 µm. Propagation losses were investigated experimentally and theoretically at wavelengths of 1.58 µm and 3.39 µm. Measured losses were found to be as low as 1.4 dB/cm at 1.58 µm and 5.1 dB/cm at 3.39 µm. Complex propagation constants for leaking modes were obtained by numerical mode analysis. It was found, that mode leakage is a major factor of… Show more

“…Therefore, more and more researches focus on the design and realization of low-cost optical waveguides with high-quality performances. [1][2][3][4][5][6][7] The technique of ion implantation, which usually includes heavy-ion implantation and light-ion implantation, has been rapidly developed in related research fields in recent years. [8,9] It has been widely used in the formation and application of optical waveguides.…”
