In this paper, we develop a technique for realizing multi-centimeter-long lithium niobate on insulator (LNOI) waveguides with a propagation loss as low as 0.027 dB/cm. Our technique relies on patterning a chromium thin film coated on the top surface of LNOI into a hard mask with a femtosecond laser followed by chemo-mechanical polishing for structuring the LNOI into the waveguides. The surface roughness on the waveguides was determined with an atomic force microscope to be 0.452 nm. The approach is compatible with other surface patterning technologies, such as optical and electron beam lithographies or laser direct writing, enabling high-throughput manufacturing of large-scale LNOI-based photonic integrated circuits.

AbstractThe impact of physical parameters of uniform fiber Bragg grating (U-FBG) like grating period, length of grating, and width of grating on the performance of U-FBG fiber by using finite differences time domain (FDTD) based on surface plasmon polaritons (SPP) is evaluated. An FBG is similar to a distributed Bragg reflector created in a small segment of optical fiber that reflects some particular wavelengths of light and transmits the other wavelengths. It is observed that the maximum received optical power at the reflected port achieved is −1.67×10-6 w/m2 with silver (Ag) profile material of U-FBG at 0.1 w/m2 input transmission power and wavelength of 1.55 μm with 0.9 μm grating length and 0.2 μm grating width. The result shows that the received optical power is changing by optimizing the physical parameters of U-FBG.
