Abstract |
We propose and demonstrate a novel four-channel monolithic polarization-diversity dual-quadrature coherent receiver with balanced detection in InP. It uses an interleave-chirped arrayed waveguide grating that acts simultaneously as a demultiplexer, 90° hybrid, and polarization splitter. |

Abstract |
A multichannel tapered coupler interfacing standard 250-μm-pitch low-NA polarization-maintaining fiber arrays with ultra-dense 20-μm-pitch high-NA silicon waveguides is designed, fabricated, and tested, demonstrating coupling losses below 1 dB and injection bandwidths of 160 Gb/s/channel. |

Abstract |
Мы представляем быстродействующий сверхпроводниковый однофотонный детектор (SSPD) для дальнего инфракрасного диапазона на основе ультратонкой монокристаллической пленки NbN толщиной 3 нм, состоящий из параллельных полосок. QE на длине волны 1,5.μм и 1,3 μм для предложенного SSPD практически одинаковы. SSPD показывает отклик длительностью 200 пс, что открывает путь к детекторам, обладающим скоростью счета свыше 1 ГГц. |

Abstract |
We present the experimental study of the direct emission – detection system based on the THz Quantum Cascade Laser as a source and Hot Electron Bolometer (HEB) detector – in view of its application as an optical communication system. We show that the system can efficiently transmit the QCL Terahertz pulses. We estimate the maximal modulation speed of the system to be about several GHz and show that it is limited only by the QCL pulse power supply, detector amplifier and connection line/wires parameters. |
