This chapter reviews the status of heterogeneous integration of silicon waveguides and
photodetectors. The most commonly used available fabrication technologies, namely …

We design a resistive heater optimized for efficient and low-loss optical phase modulation in
a silicon-on-insulator (SOI) waveguide and characterize the fabricated devices. Modulation …

We experimentally demonstrate two types of programmable, low-threshold, optically
controlled nonlinear activation functions, which are challenging to realize in photonic neural …

Compact silicon integrated devices, such as micro-ring resonators, have recently been
demonstrated as efficient sources of quantum correlated photon pairs. The mass production …

Complex photonic-integrated circuits (PIC) may have strongly non-planar topologies that
require waveguide crossings (WGX) when realized in single-layer integration platforms. The …

We present designs of all-optical SR, clocked-SR, D and T flip-flops, simultaneous single-bit
comparator-decoder and reconfigurable logic unit based on all-optical switching by two …

Lorentz reciprocity is a direct consequence of Maxwell equations governing the propagation
of light in passive linear media with symmetric permittivity and permeability tensors. Here …

A monolithically integrated multi-channel receiver fabricated on the Silicon-on-Insulator
(SOI) platform is demonstrated experimentally. This receiver is composed of an eight …

Two types of bound states in continuum (BICs), symmetry-protected and Brillouin zone
folding driven, are identified in the hollow Si nanorod arrays. By modulating the direction …

Optical networks‐on‐chip (ONoCs) are gaining momentum as a way to improve energy
consumption and bandwidth scalability in the next generation multicore and many‐core …
