A 64Gb/s 1.4pJ/b NRZ Optical-Receiver Data-Path in 14nm CMOS FinFET

Yusuf Leblebici, Alessandro Cevrero, Lukas Kull, Ilter Ozkaya, Thomas Toifl

This work describes a NRZ receiver data-path fabricated in 14nm bulk FinFET technology and characterized in an 850nm VCSEL based optical link up to 64Gb/s. It achieves 1.42pJ/bit energy efficiency while recovering PRBS-7 data (BER< 10-12) modulated by a VC ...

Twin Photon Source: Spatio-temporal Properties

We propose a method to study and characterize the spatial and temporal properties of degenerate photon pairs emitted in SPDC, using a filtering system combined with temperature variation of the nonlinear crystal. The photons can be distinguished. We relate ...

Generation and application of dynamic gratings in optical fibers using stimulated Brillouin scattering

Luc Thévenaz, Nikolay Primerov

Since the invention of optical fiber cable data transmission using light has become ubiquitous in the past years. Nonlinear optical effects, which are hardly noticed in our daily life, have become crucial and highly influential for the design and performan ...

1 Mbps coherent one-way QKD with dense wavelength division multiplexing and hardware key distillation

Andreas Peter Burg, Jeremy Hugues-Felix Constantin, Nicolas Gisin

We present the latest results obtained with a quantum cryptography prototype based on a coherent-one way quantum key distribution (QKD) scheme. To support its continuous high rate secret key generation we developed different low-noise single photon detecto ...

Raman-based distributed temperature sensor with 1 m spatial resolution over 26 km SMF using low-repetition-rate cyclic pulse coding

Marcelo Alfonso Soto Hernandez

We experimentally investigate the benefits of a new optical pulse coding technique for long-range, meter and submeter scale Raman-based distributed temperature sensing on standard single-mode optical fibers. The proposed scheme combines a low-repetition-ra ...
