A packaged phase modulator that has 3dB optical insertion loss and 7.5V Vπ at 40GHz has been successfully tested for >1W optical input power. A high-power, 40GHz modified uni-carrier traveling (MUTC) photodiode is fabricated and packaged. The developed components are discussed for analog photonic links.
A 10 GHz bandwidth photoreceiver is demonstrated. The photoreceiver consists of two photodiodes (PD) in a balanced configuration to generate a single-ended input to the transimpedance amplifier (TIA). The PDs achieves a responsivity of 0.48 A/W, and a 15 GHz bandwidth while driving a 50 D load under the designed biasing. The regulated cascode TIA is implemented in a 130 nm RF CMOS process. The TIA...
This paper is focused on the asymptotical synchronization of memristor-based neural networks with time-varying delays via adaptive controllers. In existing investigations, most results about synchronization of MNNs can only be applied to some specific MNNs. Thus, we introduce a new simple adaptive controller to synchronize two MNNs with time-varying delays asymptotically. Furthermore, some new conditions...
A phase modulated analog photonic link with interferometric detection is experimentally demonstrated. A link gain of 15 dB at 100 mA photocurrent and 10 GHz modulation frequency is achieved.
We demonstrate InP-based high power modified uni-traveling carrier photodiodes heterogeneously integrated on silicon on diamond (SOD) waveguides. These photodiodes reach 20 nA dark current at −5 V bias voltage. A 50 μm long device exhibits an internal responsivity of 1.07 A/W. The bandwidths of the devices with 14×25 μm2, 14×50 μm2, 14×100 μm2 and 14×150 μm2 area are 22 GHz, 16 GHz, 10 GHz and 7 GHz,...
We demonstrate 16.2 dB gain in a high-linearity 20 GHz IM/DD analog photonic link by utilizing a quadrature-biased dual-output Mach-Zehnder modulator and a high-power balanced photodiode.
We demonstrate InP-based modified uni-traveling carrier balanced photodiodes integrated on silicon-on-insulator (SOI) waveguides with an internal responsivity of 0.78 A/W, 14 GHz bandwidth, and >20 dB common-mode rejection ratio (CMRR). The unsaturated RF output power reaches 15.2 dBm at 20 GHz.
