Photonic-based dual-chirp microwave waveform generation with multi-carrier frequencies and large time-bandwidth product (TBWP) is proposed. In the approach, a polarization modulator is employed to introduce parabolic phase difference into the injected optical signals. After heterodyne detection in ...
today announced the launch of a 400G DR4 optical transceiver based on Silicon-Photonic (SiPh) technology to support its next-generation data center network. The new transceiver will be deployed inAlibaba Cloud'sglobal data centers starting in 2020 and will increase the network...
Recent developments in chip-based nonlinear photonics offer the tantalizing prospect of realizing many applications that can use optical frequency comb devices that have form factors smaller than 1 cm3 and that require less than 1 W of power. A key featu
In addition, as platforms are reduced in size - such as space-based platforms - these limitations become extremely critical. Optical fiber-based systems can be used to provide both data and RF signal distribution for sensors and avionics. These photonic-based systems are lighter weight, smaller ...
To the best of our knowledge, this work provides the best phase noise performance in the frequency range of 200 Hz to 40 kHz for microcomb-based systems. Importantly, it does so with integrated photonic components that can all be further combined onto a single chip with total volume of...
