We design and fabricate an eight-channel thin-film lithium niobate (TFLN) arrayed-waveguide grating (AWG) and demonstrate the electro-optical tunability of the device. The transmission of the fabri-cated TFLN AWG near the central wavelength of 1550 nm is. Arrayed waveguide grating is a versatile and scalable integrated light dispersion device, which has been widely adopted in various applications, including, optical communications and optical sensing.
Typically, periodically poled lithium niobate (PPLN) waveguides are very suitable to produce a squeezed state with high bandwidth and high squeezing (5 dB), broadband (GHz-level)
