Numerical and Experimental Methods for Estimating the Propagation Loss in Microphotonic Waveguides
Finite‐element finite‐difference time domain, eigenmode‐expansion, and volume‐current simulations are benchmarked against cut‐back, ring‐resonator, and OFDR measurements to quantify waveguide propagation loss in integrated photonic circuits. Scattering, absorption, leakage, and back‐reflection contributions are dissected; error sources are ranked; and ...

Channel control and dispersion compensation using active arrayed waveguide grating (AWG)
The role of active Arrayed-Waveguide Grating (AWG) in future dynamic Wavelength Division Multiplexing (WDM) networking and routing was investigated. Simulations were done using the Beam Propagation Method (BPM). The results of this study indicate that active AWG can be used in multiple channel control with SNR up to 19 dB and dynamic dispersion ...

Tightly‐Confined and Long Z‐Cut Lithium Niobate Waveguide with Ultralow‐Loss
A z‐cut lithium niobate waveguide is demonstrated with ultra‐low loss of 5.8 dB/m in a decimeter‐long LN spiral waveguide. This study is focused on Z‐cut LN waveguides with TE mode to avoid the material birefringence. Utilizing the third order nonlinearity, it is demonstrated that the first all‐normal‐dispersion coherent supercontinuum frequency comb ...

Mid‐infrared wavelength multiplexers on an InP platform
Abstract We demonstrate mid‐infrared multiplexers based on evanescent couplers in In0.53Ga0.47As/InP ridge waveguides. Multiplexing of λ = 5.2 µm and λ = 8 µm input wavelengths in TM00 modes to a single TM00 output was achieved with 0.7 dB insertion loss.

Improving Channel Uniformity of Multiplexer with High-Degree-of-Freedom Auxiliary Waveguides
In order to further mitigate the channel non-uniformity at the junction between the input slab and the arrayed waveguide grating in traditional AWG structures, we design a highly flexible, structurally adaptive linear auxiliary waveguide.
