A new generation of photonic integrated circuits (PICs) is being developed for application in quantum communications and quantum simulations. While the passive functionalities needed in these quantum PICs are very similar to those of their classical counterparts, light generation and detection must be controlled at the single‐photon level. III‐V semiconductors are very well suited for quantum PICs in view of their direct bandgap and corresponding ability to produce single photons by radiative recombination of excitonic states in nanostructures . In this talk I will review our recent progress in the development of multifunctional quantum PICs, including the demonstration of fully‐tuneable waveguide‐coupled single‐photon sources and of efficient waveguide single‐photon detectors on nanobeams.

In a large number of experiments or devices, noise is usually viewed as an undesirable disturbance, hindering the measurement sensitivity or device performances. In some circumstances however, noise-induced phenomena can help, as in the case of stochastic resonance whereby a weak coherent signal, compared to the barrier height of a doublewell potential, gets amplified resonantly by application of external noise. Stochastic resonance occurs in a wide class of nonlinear systems, in neurobiology, mesoscopic physics, photonics, atomic physics, mechanics…

Abstract – A long standing problem in integrated photonics is the attachment of optical fibers to an integrated photonic IC. The EU-funded project PHASTFlex takes an innovative approach to this and uses micro-electro-mechanical systems that actuate the silicon oxide-nitride optical waveguides to provide the required sub-micron alignment accuracy. Here we report on the measured movement range and coupling efficiency.

Photonic biosensors have in recent years progressed rapidly towards the goal of mobile biochemical analysis, which will enable new applications such as field-deployable medical diagnostics, mobile environmental monitoring, and distributed health-care. This progress has been achieved by leveraging the capability of photonics for precise optical metrology, and by using wafer-scale micro- and nanofabrication for massproducing sensors, in particular from silicon and related materials. However, to deliver on the full promise of photonic biosensors, remaining challenges include the handling of liquids on the microscale and the on-chip integration of light sources and detectors. Here, we discuss our recent work on these two fronts.
