Arrayed waveguide grating (AWG) is one of the primary devices wavelength division multiplexing (WDM) technology with comprehensive advantages stable performance, high resolution, and a large number channels. In this work, we demonstrated low-loss AWG 100 output channels channel spacing 50 pm based on z-cut thin-film lithium niobate platform. The length increment adjacent arrayed waveguides etching depth have been optimized to reduce random phase errors. As far as know, has largest smallest...

Arrayed waveguide grating (AWG) is the core optical device in ultra-large capacity wavelength division multiplexing system, which can be used many fields such as filtering, meter, wave and demultiplexing. In this paper, we propose an 100 channel AWG based on Z-cut lithium niobate platform with intervals of 50 pm insertion loss 13 dB.
Optical resonator-based Kerr frequency combs allow an ultra-precise time and measurements for a wide range of applications including ranging, biosensing, high-capacity communications, quantum information technology.Kerr solitons are coherent that crucial synthesizer chronometric instruments.The behavior the soliton is determined by multiple factors while key challenge stable operation to maintain thermal equilibrium in resonator.In this work, owing stabilizing effect caused neighboring...
Dynamic dual-microcombs are demonstrated in a Si 3 N 4 microresonator using single pump, yielding the microwave signals at ~23.4, ~28.9, and ~34.6 GHz. The results of interest for applications integrated photonics.
We demonstrate various octave-spanning soliton crystals in a Si 3 N 4 microresonator. The conversion efficiency can reach above 50% and the repetition rate (f rep ) be tuned from 6 to 8 THz.
A photonic integrated spatial mode controller was demonstrated, which consisted of a 100-channel arrayed-waveguide-grating (AWG), phase and amplitude modulator array reflector based on the thin-film z-cut lithium niobate platform. The fabricated chip exhibited narrow channel interval about 50 pm. measured response time Mach-Zehnder interferometer (MZI) is less than 0.5 us.
Octave-spanning single-soliton and soliton crystals with repetition rates of 1, 2, 3 THz are demonstrated in a Si N 4 microresonator. A step ~0.09 nm (~11 GHz) is achieved using slow pump tuning.
We demonstrate the steady-state dissipative Kerr soliton with a 33-GHz single-soliton step and 30-GHz existence window, by tuning pump laser at an adiabatic scanning speed (1nm/s) mode, respectively.
