16-Wavelength DFB Laser Array With High Channel-Spacing Uniformity Based on Equivalent Phase-Shift Technique

IEEE Photonics Journal, 2014
The high accuracy of lasing wavelength spacing is one of the key requirements of a distributed feedback (DFB) semiconductor laser array. However, the nonuniformity of the wavelength spacing is increasingly deteriorating with the increase in the channel ...

Non-absorbing high-efficiency counter for itinerant microwave photons [PDF]

, 2014
Detecting an itinerant microwave photon with high efficiency is an outstanding problem in microwave photonics and its applications. We present a scheme to detect an itinerant microwave photon in a transmission line via the nonlinearity provided by a ...

Itinerant Microwave Photon Detector

Physical Review Letters, 2018
The realization of a high-efficiency microwave single photon detector is a long-standing problem in the field of microwave quantum optics. Here we propose a quantum non-demolition, high-efficiency photon detector that can readily be implemented in present state-of-the-art circuit quantum electrodynamics.

WDM–TDM NG-PON Power Budget Extension by Utilizing SOA in the Remote Node

IEEE Photonics Journal, 2014
Today, even in access networks, data traffic is enormously increasing, a trend that causes existing passive optical network (PON) infrastructures to become bottlenecks in a tele- and data-communication infrastructure, which is aimed to be both broadband ...
