Integrated photonic circuits are one of the most promising platforms for large-scale photonic quantum information systems due to their small physical size and stable interferometers with near-perfect lateral-mode overlaps. Since many quantum information protocols are based on qubits defined by the polarization of photons, we must develop integrated building blocks to generate, manipulate, and m...

We present a numerical study of a passive integrated photonics reservoir computing platform based on multimodal Y-junctions. We propose a novel design of this junction where the level of adiabaticity is carefully tailored to capture the radiation loss in higher-order modes, while at the same time providing additional mode mixing that increases the richness of the reservoir dynamics. With this d...

The integration scale in Photonic Integrated Circuits will be pushed to VLSI-level in the coming decade. Key technologies for reduction of device dimensions are high resolution lithography and deep waveguide etching technology. In this paper developments in Photonic Integration are reviewed and the limits for reduction of device dimensions are discussed. ©2004 Optical Society of America OCIS co...

The optical logic unit cell is the photonic analog to transistor-transistor logic in electronic devices. Active devices such as InP-based semiconductor optical amplifiers (SOA) emitting at 1550 nm are vertically integrated with passive waveguides using the asymmetric twin waveguide technique and the SOAs are placed in a Mach-Zehnder interferometer (MZI) configuration. By sending in high-intensi...

Silicon-based photonic components are especially attractive for realizing low-cost photonic integrated circuits (PICs) using high-volume manufacturing processes (Heck et al., 2013). Due to its transparency in the telecommunications wavelength bands near 1310 and 1550 nm, silicon is an excellent material for realizing low-loss passive optical components. For the same reason, it is not a strong c...
