Highly efficient ultra-broad beam silicon nanophotonic antenna based on near-field phase engineering
Shahrzad Khajavi, Daniele Melati, Pavel Cheben +3
Optical antennas are a fundamental element in optical phased arrays (OPA) and free-space optical interconnects. An outstanding challenge in optical antenna design lies in achieving…
Broadband behavior of quadratic metalenses with a wide field of view
Yang Liu, Jianhao Zhang, Xavier Le Roux +5
Metalenses are attracting a large interest for the implementation of complex optical functionalities in planar and compact devices. However, chromatic and off-axis aberrations rema…
PCA-Boosted Autoencoders for Nonlinear Dimensionality Reduction in Low Data Regimes
Muhammad Al-Digeil, Yuri Grinberg, Daniele Melati3 +5
Autoencoders (AE) provide a useful method for nonlinear dimensionality reduction but are ill-suited for low data regimes. Conversely, Principal Component Analysis (PCA) is data-eff…
Athermal and tunable echelle grating wavelength demultiplexers using a Mach-Zehnder interferometer launch structure
Daniele Melati, Dan-Xia Xu, Ross Cheriton +5
We present a comparative experimental study of three silicon photonic echelle grating demultiplexers that are integrated with a Mach-Zehnder interferometer (MZI) launch structure.…
