Inverse design of efficient waveguide crossing with phase correction
Abstract:
We designed, fabricated, and experimentally characterized a waveguide crossing with phase-correction functionality. Implemented on a silicon-on-insulator (SOI) platform with an 8 × 8 µm2 footprint, it achieves simultaneous optimization of transmission efficiency and phase response via an objective function incorporating insertion loss (IL) and phase error. Experimental results show that, over the wavelength range of 1535-1565 nm, the proposed device exhibits an average IL below 0.11 dB and a phase error of 1.86∘ for the TE0 mode.

Two special sources may be considered when they are in phase. This can be easily achieved by feeding the two sources from the same source. An example would be synchronizing the two speakers by feeding them with the same source, such as the sound waves produced by a tuning fork. This setup ensures that the two sources have the same frequency and are...
