Abstract:

”Silicon photonics, a rapidly evolving field, has gathered substantial attention due to its potential to revolutionize information technology by enabling the integration of photonic and electronic components on a single chip. One of the critical aspects in silicon photonics is the efficient coupling of light to and from the photonic chip. This study delves into the design and analysis of low-loss silicon nitride (SiN) coupling interfaces, recognizing their paramount importance in enhancing the performance of integrated photonics devices.

Efficient coupling interfaces are essential for achieving maximum light throughput and minimizing signal losses. However, coupling interfaces in silicon photonics face significant challenges. These challenges include impedance matching, mode overlap, and propagation losses, all of which directly impact the overall efficiency of the photonic devices. Simulations are used to optimize the design of edge coupling interfaces in silicon photonics, investigating various design parameters to identify the optimal configurations that minimize coupling losses. Subsequently, the reasons behind the discrepancies observed between simulation results and experimental data are explored.”
