As the only method for all-time, all-weather, and long-distance environmental monitoring target detection, radar is considered an essential sensor future intelligent applications. However, electronic radars face critical challenges in terms of frequency range, bandwidth, processing speed, leading to poor resolution, slow response, being easy be interfered. A microwave photonic cognitive with a subcentimeter resolution reported, adaptively utilizing opportunistic spectra potential...
High-power photodiodes (PDs) driving ultrawide antennas directly arises as a promising solution for multi-band, high-efficiency and low-complexity RF front ends since bandwidth-limited electrical power amplifiers are removed. However, high-power performance of PDs is usually hardly to be exerted in simple low-cost directly-modulated photonic link, due the terrible modulation depth laser (DML). This letter proposes demonstrates new method optimize DML photodiodes-driven-antennas link by using...
A dual-band RF receiver with large crosstalk suppression is proposed and demonstrated based on photonic imagereject mixing polarization multiplexing. Dual-band signals in the X- Ku-bands 1-GHz instantaneous bandwidth are simultaneously downconverted to same IF band of than 30 dB.
In this work, three approaches are proposed to implement high-speed 850-nm optical receivers fully in standard bulk 0.18 μm silicon (Si) CMOS technology. the first approach, lateral p-i-n photodiode (PD) with designed block well limit photocarriers being generated from laterally depleted regions is integrated receiver. The receiver consists of TIA, LA, offset-cancellation-network and buffer provide a conversion gain 110 dBΩ data rate 2.5 Gbps operation. second receiver, spatially modulated...
