… In general, we design grating couplers with the intention of coupling an input waveguide
mode to a desired output waveguide (eg an optical fiber) or free-space mode. As is such, the …

… We apply our inverse design approach to the layer stack used in [23] (air-cladded, 220 nm
SOI, 3 μm buried oxide (BOX) layer), operating conditions (1550 nm source), and feature size (…

… Here, we provide a full demonstration of the inverse design technique's power by … -demultiplexing
grating coupler fabricated in silicon-on-insulator (SOI). The grating accepts a vertically …

… in the design of photonic devices, such as grating couplers. We show that PHORCED obtains
better performing grating coupler designs than local gradient-based inverse design via the …

… degree of photonics inverse design which is experimentally realized in this work. … non-intuitive
design methodologies (ie, inverse design) are a fundamentally important design resource …

… In summary, both forward and inverse design approaches based on DNN to design a silicon
photonic grating coupler are studied comparably. To the best of our knowledge, this is the …

… The simulation and inverse design approach used in this paper for modeling and optimization
of the grating coupler wavelength demultiplexer is described in detail in Sideris et al. . …

… designed grating coupler differs from this design in that we have fabricated and experimentally
verified the designed grating coupler. … in both designs, our designed grating coupler was …

… coupling efficiency, polarization and wavelength sensitivity. Finally, we discuss some emerging
research topics on grating couplers… as non-uniform GCs using inverse design [87,88] that …

… an inverse design process to optimize the fin grating coupler and achieve <1 dB loss on 220
nm SOI, which is the lowest loss for grating couplers … the grating coupler performances in the …
